Cavitation fatigue. Embolism and refilling cycles can weaken the cavitation resistance of xylem. (1/566)

Although cavitation and refilling cycles could be common in plants, it is unknown whether these cycles weaken the cavitation resistance of xylem. Stem or petiole segments were tested for cavitation resistance before and after a controlled cavitation-refilling cycle. Cavitation was induced by centrifugation, air drying of shoots, or soil drought. Except for droughted plants, material was not significantly water stressed prior to collection. Cavitation resistance was determined from "vulnerability curves" showing the percentage loss of conductivity versus xylem pressure. Two responses were observed. "Resilient" xylem (Acer negundo and Alnus incana stems) showed no change in cavitation resistance after a cavitation-refilling cycle. In contrast, "weakened" xylem (Populus angustifolia, P. tremuloides, Helianthus annuus stems, and Aesculus hippocastanum petioles) showed considerable reduction in cavitation resistance. Weakening was observed whether cavitation was induced by centrifugation, air dehydration, or soil drought. Observations from H. annuus showed that weakening was proportional to the embolism induced by stress. Air injection experiments indicated that the weakened response was a result of an increase in the leakiness of the vascular system to air seeding. The increased air permeability in weakened xylem could result from rupture or loosening of the cellulosic mesh of interconduit pit membranes during the water stress and cavitation treatment.  (+info)

How aphids lose their marbles. (2/566)

Insects provide examples of many cunning stratagems to cope with the challenges of living in a world dominated by surface forces. Despite being the current masters of the land environment, they are at constant risk of being entrapped in liquids, which they prevent by having waxy and hairy surfaces. The problem is particularly acute in an enclosed space, such as a plant gall. Using secreted wax to efficiently parcel and transport their own excrement, aphids were able to solve this problem 200 Myr ago. Here, we report on the physical and physiological significance of this ingenious solution. The secreted powdery wax has three distinct roles: (i) it is hydrophobic, (ii) it creates a microscopically rough inner gall surface made of weakly compacted wax needles making the gall ultra-hydrophobic, and (iii) it coats the honeydew droplets converting them into liquid marbles, that can be rapidly and efficiently moved.  (+info)

A hierarchical statistical model for estimating population properties of quantitative genes. (3/566)

BACKGROUND: Earlier methods for detecting major genes responsible for a quantitative trait rely critically upon a well-structured pedigree in which the segregation pattern of genes exactly follow Mendelian inheritance laws. However, for many outcrossing species, such pedigrees are not available and genes also display population properties. RESULTS: In this paper, a hierarchical statistical model is proposed to monitor the existence of a major gene based on its segregation and transmission across two successive generations. The model is implemented with an EM algorithm to provide maximum likelihood estimates for genetic parameters of the major locus. This new method is successfully applied to identify an additive gene having a large effect on stem height growth of aspen trees. The estimates of population genetic parameters for this major gene can be generalized to the original breeding population from which the parents were sampled. A simulation study is presented to evaluate finite sample properties of the model. CONCLUSIONS: A hierarchical model was derived for detecting major genes affecting a quantitative trait based on progeny tests of outcrossing species. The new model takes into account the population genetic properties of genes and is expected to enhance the accuracy, precision and power of gene detection.  (+info)

A preliminary investigation of the role of auxin and cytokinin in sylleptic branching of three hybrid poplar clones exhibiting contrasting degrees of sylleptic branching. (4/566)

Sylleptic branches grow out from lateral buds during the same growing season in which the buds are formed. This type of branching is present in poplar and in many tropical species. It results in the production of more branches, more leaves and expanded photosynthetic capacity and is thought to assist in increasing the overall growth and biomass of the tree at a young age. However, very little is known about the physiology of sylleptic branching in poplar, which is an extremely important source of fibre and fuel. In the present study of three hybrid poplar clones (11-11, 47-174 and 49-177) of Populus trichocarpa x P. deltoides exhibiting contrasting degrees of sylleptic branching, an analysis was carried out on parent shoot elongation and sylleptic branching, together with a preliminary comparison of the parent shoots' sensitivity to auxin (naphthaleneacetic acid) as a repressor of lateral bud outgrowth, and cytokinin (benzyladenine) as a promoter. Suggestive evidence was found for an inverse correlation between parent shoot sensitivity to auxin and the degree of sylleptic branching, as well as a partially positive correlation with respect to sensitivity to cytokinin. The present data are consistent with the hypothesis that auxin and cytokinin may play repressive and promotive roles, respectively, in the sylleptic branching of hybrid poplar.  (+info)

Differential expression of two distinct phenylalanine ammonia-lyase genes in condensed tannin-accumulating and lignifying cells of quaking aspen. (5/566)

Lignins, along with condensed tannins (CTs) and salicylate-derived phenolic glycosides, constitute potentially large phenylpropanoid carbon sinks in tissues of quaking aspen (Populus tremuloides Michx.). Metabolic commitment to each of these sinks varies during development and adaptation, and depends on L-phenylalanine ammonia-lyase (PAL), an enzyme catalyzing the deamination of L-phenylalanine to initiate phenylpropanoid metabolism. In Populus spp., PAL is encoded by multiple genes whose expression has been associated with lignification in primary and secondary tissues. We now report cloning two differentially expressed PAL cDNAs that exhibit distinct spatial associations with CT and lignin biosynthesis in developing shoot and root tissues of aspen. PtPAL1 was expressed in certain CT-accumulating, non-lignifying cells of stems, leaves, and roots, and the pattern of PtPAL1 expression varied coordinately with that of CT accumulation along the primary to secondary growth transition in stems. PtPAL2 was expressed in heavily lignified structural cells of shoots, but was also expressed in non-lignifying cells of root tips. Evidence of a role for Pt4CL2, encoding 4-coumarate:coenzyme A ligase, in determining CT sink strength was gained from cellular co-expression analysis with PAL1 and CTs, and from experiments in which leaf wounding increased PAL1 and 4CL2 expression as well as the relative allocation of carbon to CT with respect to phenolic glycoside, the dominant phenolic sink in aspen leaves. Leaf wounding also increased PAL2 and lignin pathway gene expression, but to a smaller extent. The absence of PAL2 in most CT-accumulating cells provides in situ support for the idea that PAL isoforms function in specific metabolic milieus.  (+info)

Characterization of SP1, a stress-responsive, boiling-soluble, homo-oligomeric protein from aspen. (6/566)

sp1 cDNA was isolated from aspen (Populus tremula) plants by immunoscreening an expression library using polyclonal antibodies against BspA protein. BspA, which is a boiling-stable protein, accumulates in aspen plants in response to water stress and abscisic acid application (Pelah et al., 1995). The sp1 cDNA was found to encode a 12.4-kD generally hydrophilic protein with a hydrophobic C terminus, which is different from the BspA protein and was termed SP1 (stable protein 1). Northern-blot analysis revealed that sp1 encodes a small mRNA (about 0.6 kb) that is expressed in aspen plants under non-stress conditions and is accumulated after salt, cold, heat, and desiccation stress, and during the recovery from stress. The SP1 detected in plants remained soluble upon boiling, migrated both as a 12.4-kD band and a much higher mass of 116 kD on a 17% (w/v) Tricine-sodium dodecyl sulfate-polyacrylamide gel. Comparative protease digestion patterns, amino acid analyses, and the N-terminal sequences of the 12.4- and 116-kD proteins revealed that SP1 is homo-oligomeric. Furthermore, gel filtration chromatography analysis indicated that SP1 exists in aspen plants as a complex, composed of 12 subunits of 12.4 kD. A large number of sequences deduced from expressed sequence tags and genomic sequences of other organisms with unknown function show high homology to SP1. Thus, SP1 may represent a new protein family. Here, we present the first report on this putative protein family: the cloning, isolation, and characterization of SP1, a stress-responsive, boiling-soluble, oligomeric protein.  (+info)

Populus: arabidopsis for forestry. Do we need a model tree? (7/566)

Trees are used to produce a variety of wood-based products including timber, pulp and paper. More recently, their use as a source of renewable energy has also been highlighted, as has their value for carbon mitigation within the Kyoto Protocol. Relative to food crops, the domestication of trees has only just begun; the long generation time and complex nature of juvenile and mature growth forms are contributory factors. To accelerate domestication, and to understand further some of the unique processes that occur in woody plants such as dormancy and secondary wood formation, a 'model' tree is needed. Here it is argued that Populus is rapidly becoming accepted as the 'model' woody plant and that such a 'model' tree is necessary to complement the genetic resource being developed in arabidopsis. The genus Populus (poplars, cottonwoods and aspens) contains approx. 30 species of woody plant, all found in the Northern hemisphere and exhibiting some of the fastest growth rates observed in temperate trees. Populus is fulfilling the 'model' role for a number of reasons. First, and most important, is the very recent commitment to sequence the Populus genome, a project initiated in February 2002. This will be the first woody plant to be sequenced. Other reasons include the relatively small genome size (450-550 Mbp) of Populus, the large number of molecular genetic maps and the ease of genetic transformation. Populus may also be propagated vegetatively, making mapping populations immortal and facilitating the production of large amounts of clonal material for experimentation. Hybridization occurs routinely and, in these respects, Populus has many similarities to arabidopsis. However, Populus also differs from arabidopsis in many respects, including being dioecious, which makes selfing and back-cross manipulations impossible. The long time-to-flower is also a limitation, whilst physiological and biochemical experiments are more readily conducted in Populus compared with the small-statured arabidopsis. Recent advances in the development of large expressed sequence tagged collections, microarray analysis and the free distribution of mapping pedigrees for quantitative trait loci analysis secure Populus as the ideal subject for further exploitation by a wide range of scientists including breeders, physiologists, biochemists and molecular biologists. In addition, and in contrast to other model plants, the genus Populus also has genuine commercial value as a tree for timber, plywood, pulp and paper.  (+info)

Xyloglucan endotransglycosylases have a function during the formation of secondary cell walls of vascular tissues. (8/566)

Xyloglucan transglycosylases (XETs) have been implicated in many aspects of cell wall biosynthesis, but their function in vascular tissues, in general, and in the formation of secondary walls, in particular, is less well understood. Using an in situ XET activity assay in poplar stems, we have demonstrated XET activity in xylem and phloem fibers at the stage of secondary wall formation. Immunolocalization of fucosylated xylogucan with CCRC-M1 antibodies showed that levels of this species increased at the border between the primary and secondary wall layers at the time of secondary wall deposition. Furthermore, one of the most abundant XET isoforms in secondary vascular tissues (PttXET16A) was cloned and immunolocalized to fibers at the stage of secondary wall formation. Together, these data strongly suggest that XET has a previously unreported role in restructuring primary walls at the time when secondary wall layers are deposited, probably creating and reinforcing the connections between the primary and secondary wall layers. We also observed that xylogucan is incorporated at a high level in the inner layer of nacreous walls of mature sieve tube elements.  (+info)

I'm sorry for any confusion, but "Populus" is not a medical term. It is actually the genus name for a group of trees commonly known as poplars, aspens, and cottonwoods. If you have any medical terms or concepts that you would like me to define or explain, I would be happy to help!

I apologize for any confusion, but "Salicaceae" is not a medical term. It is a taxonomic category in botany, specifically a family of flowering plants that includes willows, poplars, and sallows. The plants in this family are known for their production of salicylic acid, which is a precursor to aspirin. If you have any questions related to medical terminology or concepts, I would be happy to help with those instead!

I'm sorry for any confusion, but "Wood" is not a medical term. It is a common name for various hard, fibrous tissues that make up the trunks and branches of trees and shrubs, as well as a term used for a wide range of items made from these materials. If you have any medical concerns or questions, I would be happy to try and help answer those for you.

I'm sorry for any confusion, but "trees" is not a medical term. It is a common term used in various fields, including biology, ecology, and dendrology, to refer to a woody perennial plant with a single stem or trunk that supports branches and leaves in most species.

If you have any questions related to medical terminology or health-related topics, please provide more context so I can offer an accurate and helpful response.

Xylem is a term used in the field of botany and plant anatomy, but I understand you're asking for a medical definition. In human anatomy, there isn't a direct structure equivalent to xylem. However, I can provide the general definition of xylem from its botanical context:

Xylem is one of the two types of vascular tissues in plants (the other being phloem). It is responsible for transporting water and dissolved nutrients from the roots to various parts of the plant, including stems, leaves, and flowers. Xylem consists of several types of cells, including vessels, tracheids, xylem fibers, and xylem parenchyma. The transportation in xylem occurs due to the cohesion-tension mechanism, where water is pulled up through the plant via transpiration pull.

A plant stem is not typically defined in a medical context, but rather in the field of botany. However, I can certainly provide a general biological definition for you.

In plants, stems are organs that serve primarily as support structures, holding leaves, flowers, and fruits aloft where they can receive sunlight and exchange gases. They also act as conduits, transporting water, nutrients, and sugars made during photosynthesis between the roots and shoots of a plant.

The stem is usually composed of three main tissue systems: dermal, vascular, and ground. The dermal tissue system forms the outermost layer(s) of the stem, providing protection and sometimes participating in gas exchange. The vascular tissue system contains the xylem (which transports water and nutrients upward) and phloem (which transports sugars and other organic compounds downward). The ground tissue system, located between the dermal and vascular tissues, is responsible for food storage and support.

While not a direct medical definition, understanding the structure and function of plant stems can be relevant in fields such as nutrition, agriculture, and environmental science, which have implications for human health.

A gene in plants, like in other organisms, is a hereditary unit that carries genetic information from one generation to the next. It is a segment of DNA (deoxyribonucleic acid) that contains the instructions for the development and function of an organism. Genes in plants determine various traits such as flower color, plant height, resistance to diseases, and many others. They are responsible for encoding proteins and RNA molecules that play crucial roles in the growth, development, and reproduction of plants. Plant genes can be manipulated through traditional breeding methods or genetic engineering techniques to improve crop yield, enhance disease resistance, and increase nutritional value.

I'm sorry for any confusion, but "Lignin" is not a medical term. It is a term used in the field of biology and chemistry, particularly in botany and wood science. Lignin is a complex organic polymer that binds cellulose fibers together, providing strength and rigidity to the cell walls of plants. It is a major component of wood and bark.

If you have any medical terms you would like defined or any other questions, please let me know!

I believe there may be a slight misunderstanding in your question. "Plant leaves" are not a medical term, but rather a general biological term referring to a specific organ found in plants.

Leaves are organs that are typically flat and broad, and they are the primary site of photosynthesis in most plants. They are usually green due to the presence of chlorophyll, which is essential for capturing sunlight and converting it into chemical energy through photosynthesis.

While leaves do not have a direct medical definition, understanding their structure and function can be important in various medical fields, such as pharmacognosy (the study of medicinal plants) or environmental health. For example, certain plant leaves may contain bioactive compounds that have therapeutic potential, while others may produce allergens or toxins that can impact human health.

A plant genome refers to the complete set of genetic material or DNA present in the cells of a plant. It contains all the hereditary information necessary for the development and functioning of the plant, including its structural and functional characteristics. The plant genome includes both coding regions that contain instructions for producing proteins and non-coding regions that have various regulatory functions.

The plant genome is composed of several types of DNA molecules, including chromosomes, which are located in the nucleus of the cell. Each chromosome contains one or more genes, which are segments of DNA that code for specific proteins or RNA molecules. Plants typically have multiple sets of chromosomes, with each set containing a complete copy of the genome.

The study of plant genomes is an active area of research in modern biology, with important applications in areas such as crop improvement, evolutionary biology, and medical research. Advances in DNA sequencing technologies have made it possible to determine the complete sequences of many plant genomes, providing valuable insights into their structure, function, and evolution.

Gene expression regulation in plants refers to the processes that control the production of proteins and RNA from the genes present in the plant's DNA. This regulation is crucial for normal growth, development, and response to environmental stimuli in plants. It can occur at various levels, including transcription (the first step in gene expression, where the DNA sequence is copied into RNA), RNA processing (such as alternative splicing, which generates different mRNA molecules from a single gene), translation (where the information in the mRNA is used to produce a protein), and post-translational modification (where proteins are chemically modified after they have been synthesized).

In plants, gene expression regulation can be influenced by various factors such as hormones, light, temperature, and stress. Plants use complex networks of transcription factors, chromatin remodeling complexes, and small RNAs to regulate gene expression in response to these signals. Understanding the mechanisms of gene expression regulation in plants is important for basic research, as well as for developing crops with improved traits such as increased yield, stress tolerance, and disease resistance.

"Plant proteins" refer to the proteins that are derived from plant sources. These can include proteins from legumes such as beans, lentils, and peas, as well as proteins from grains like wheat, rice, and corn. Other sources of plant proteins include nuts, seeds, and vegetables.

Plant proteins are made up of individual amino acids, which are the building blocks of protein. While animal-based proteins typically contain all of the essential amino acids that the body needs to function properly, many plant-based proteins may be lacking in one or more of these essential amino acids. However, by consuming a variety of plant-based foods throughout the day, it is possible to get all of the essential amino acids that the body needs from plant sources alone.

Plant proteins are often lower in calories and saturated fat than animal proteins, making them a popular choice for those following a vegetarian or vegan diet, as well as those looking to maintain a healthy weight or reduce their risk of chronic diseases such as heart disease and cancer. Additionally, plant proteins have been shown to have a number of health benefits, including improving gut health, reducing inflammation, and supporting muscle growth and repair.

I'm sorry for any confusion, but "Pentanes" is not a medical term. It is a chemical term that refers to a group of five-carbon alkane hydrocarbons, including n-pentane and iso-pentane. These substances can be used in medical settings as anesthetics or for medical research, but "Pentanes" itself does not have a specific medical definition.

In the context of medicine and biology, cambium is not a term that is commonly used. However, in botany, cambium refers to a thin layer of cells found between the bark and the wood of a tree or shrub. This tissue is responsible for the growth of the stem by producing new cells that become part of the wood (xylem) or the inner bark (phloem).

The vascular cambium is a meristematic tissue, which means it contains undifferentiated cells that can divide and differentiate into specialized cell types. In addition to the vascular cambium, there is also a cork cambium or phellogen, which produces the outermost layers of the bark.

While not a medical term per se, an understanding of cambium is important in fields such as dendrology (the study of trees) and plant physiology, which have applications in medicine and health.

"Drought" is not a medical term. It is a term used in meteorology and environmental science to refer to a prolonged period of abnormally low rainfall, leading to water shortage and scarcity in the affected areas. Droughts can have various impacts on human health, including dehydration, heat-related illnesses, reduced air quality, increased transmission of waterborne diseases, and mental health issues related to stress and displacement. However, drought itself is not a medical condition.

"Laccaria" is a genus of fungi in the family Hydnangiaceae. These mushrooms are commonly known as "deer shields" or "coral deershrooms." They are characterized by their distinctive cap, which is often brightly colored in shades of orange, red, or brown and has a sticky surface. The gills are decurrent, meaning they extend down the stem, and the spores are pinkish-brown. These fungi form mycorrhizal relationships with the roots of trees and other plants, helping to facilitate nutrient uptake. They are found in wooded areas throughout the world and are considered edible, although some species may cause digestive upset in sensitive individuals.

Phylogeny is the evolutionary history and relationship among biological entities, such as species or genes, based on their shared characteristics. In other words, it refers to the branching pattern of evolution that shows how various organisms have descended from a common ancestor over time. Phylogenetic analysis involves constructing a tree-like diagram called a phylogenetic tree, which depicts the inferred evolutionary relationships among organisms or genes based on molecular sequence data or other types of characters. This information is crucial for understanding the diversity and distribution of life on Earth, as well as for studying the emergence and spread of diseases.

"Salix" is the genus name for a group of plants commonly known as willows. These are deciduous trees and shrubs that belong to the family Salicaceae. While "Salix" is not a medical term itself, certain species of willow have been used in medicine for their medicinal properties.

For instance, the bark of white willow (Salix alba) contains salicin, which has anti-inflammatory and analgesic effects similar to aspirin. The use of willow bark extract as a natural pain reliever and fever reducer dates back thousands of years in various traditional medicine systems.

However, it's important to note that the modern medical definition of "salicylate" refers to a group of compounds that includes both naturally occurring substances like salicin found in willow bark and synthetic derivatives such as aspirin (acetylsalicylic acid). These compounds share similar therapeutic properties and are used to treat pain, inflammation, and fever.

Ribonucleic acid (RNA) in plants refers to the long, single-stranded molecules that are essential for the translation of genetic information from deoxyribonucleic acid (DNA) into proteins. RNA is a nucleic acid, like DNA, and it is composed of a ribose sugar backbone with attached nitrogenous bases (adenine, uracil, guanine, and cytosine).

In plants, there are several types of RNA that play specific roles in the gene expression process:

1. Messenger RNA (mRNA): This type of RNA carries genetic information copied from DNA in the form of a sequence of three-base code units called codons. These codons specify the order of amino acids in a protein.
2. Transfer RNA (tRNA): tRNAs are small RNA molecules that serve as adaptors between the mRNA and the amino acids during protein synthesis. Each tRNA has a specific anticodon sequence that base-pairs with a complementary codon on the mRNA, and it carries a specific amino acid that corresponds to that codon.
3. Ribosomal RNA (rRNA): rRNAs are structural components of ribosomes, which are large macromolecular complexes where protein synthesis occurs. In plants, there are several types of rRNAs, including the 18S, 5.8S, and 25S/28S rRNAs, that form the core of the ribosome and help catalyze peptide bond formation during protein synthesis.
4. Small nuclear RNA (snRNA): These are small RNA molecules that play a role in RNA processing, such as splicing, where introns (non-coding sequences) are removed from pre-mRNA and exons (coding sequences) are joined together to form mature mRNAs.
5. MicroRNA (miRNA): These are small non-coding RNAs that regulate gene expression by binding to complementary sequences in target mRNAs, leading to their degradation or translation inhibition.

Overall, these different types of RNAs play crucial roles in various aspects of RNA metabolism, gene regulation, and protein synthesis in plants.

Genetically modified plants (GMPs) are plants that have had their DNA altered through genetic engineering techniques to exhibit desired traits. These modifications can be made to enhance certain characteristics such as increased resistance to pests, improved tolerance to environmental stresses like drought or salinity, or enhanced nutritional content. The process often involves introducing genes from other organisms, such as bacteria or viruses, into the plant's genome. Examples of GMPs include Bt cotton, which has a gene from the bacterium Bacillus thuringiensis that makes it resistant to certain pests, and golden rice, which is engineered to contain higher levels of beta-carotene, a precursor to vitamin A. It's important to note that genetically modified plants are subject to rigorous testing and regulation to ensure their safety for human consumption and environmental impact before they are approved for commercial use.

Mesophyll cells are photosynthetic cells located in the interior tissue of a leaf, specifically within the chloroplast-containing portion called the mesophyll. These cells are responsible for capturing sunlight and converting it into chemical energy through the process of photosynthesis. They can be further divided into two types: palisade mesophyll cells and spongy mesophyll cells.

Palisade mesophyll cells are columnar-shaped cells that contain many chloroplasts and are located closer to the upper epidermis of the leaf. They are arranged in one or more layers and are primarily responsible for capturing light during photosynthesis.

Spongy mesophyll cells, on the other hand, are loosely arranged and have a sponge-like structure. They contain fewer chloroplasts than palisade mesophyll cells and are located closer to the lower epidermis of the leaf. These cells facilitate gas exchange between the plant and the environment by allowing for the diffusion of carbon dioxide into the leaf and oxygen out of the leaf.

Overall, mesophyll cells play a critical role in photosynthesis and help to maintain the health and growth of the plant.
