Antioxidant properties of Mediterranean food plant extracts: geographical differences. (1/15)
Locally grown, wild food plants seasonally contribute a considerable portion of the daily diet in certain Mediterranean areas and it has been suggested that the beneficial effects of the Mediterranean diet on human health partly originate from the antioxidant effect of flavonoid-rich food plants. The nutrient content of most wild plants is higher than that of cultivated ones and may vary depending on the prevailing environmental conditions. Accordingly, three local Mediterranean plant foods (i.e. Cichorium intybus, Sonchus oleraceus, Papaver rhoeas) were collected in Greece (Crete), southern Italy, and southern Spain in order to assess possible differences in their in vitro antioxidant potential. The biological assays revealed diverse intra-plant specific antioxidant effects for the tested extracts ranging from no activity to almost complete protection. Furthermore, substantial differences in the polyphenol content were found for the nutritionally used part of the same plant originating from different locations. However, no clear correlations between the polyphenol content and the extracts' antioxidant activities were found. Taken together, the data suggest that certain local Mediterranean plant foods possess promising antioxidant activity and that the observed biological effects are possibly influenced by the geographically-dependent environmental conditions prevailing during plant growth. (+info)Role of the sonchus yellow net virus N protein in formation of nuclear viroplasms. (2/15)
Sonchus yellow net virus is a plant nucleorhabdovirus whose nucleocapsid (N), phosphoprotein (P), and polymerase (L) proteins form large viroplasms in the nuclei of infected plants (C. R. F. Martins, J. A. Johnson, D. M. Lawrence, T. J. Choi, A. Pisi, S. L. Tobin, D. Lapidus, J. D. O. Wagner, S. Ruzin, K. McDonald, and A. O. Jackson, J. Virol. 72:5669-5679, 1998). When expressed alone, the N protein localizes to the nuclei of plant and yeast (Saccharomyces cerevisiae) cells and the P protein is distributed throughout the cells, but coexpression of N and P results in formation of subnuclear viroplasm-like foci (M. M. Goodin, J. Austin, R. Tobias, M. Fujita, C. Morales, and A. O. Jackson, J. Virol. 75:9393-9406, 2001; M. M. Goodin, R. G. Dietzgen, D. Schichnes, S. Ruzin, and A. O. Jackson, Plant J. 31:375-383, 2002). We now show that the N protein and various fluorescent derivatives form similar subnuclear foci in plant cells and that homologous interactions mediated by a helix-loop-helix region near the amino terminus are required for formation of the foci. Mutations within the helix-loop-helix region also interfere with N- and P-protein interactions that are required for N and P colocalization in the subnuclear foci. Affinity purification of N proteins harboring single mutations within the motif revealed that Tyr40 is critical for N-N and N-P interactions. Additional in vitro binding assays also indicated that the N protein binds to yeast and plant importin alpha homologues, whereas mutations in the carboxy-terminal nuclear localization signal abrogate importin alpha binding. The P protein did not bind to the importin alpha homologues, suggesting that the N and P proteins use different pathways for nuclear entry. Our results in toto support a model suggesting that during infection, the N and P proteins enter the nucleus independently, that viroplasm formation requires homologous N-protein interactions, and that P protein targeting to the viroplasm requires N-P protein interactions that occur after N and P protein import into the nucleus. (+info)Mapping unexplored genomes: a genetic linkage map of the woody sonchus alliance (Asteraceae: Sonchinae) in the Macaronesian Islands. (3/15)
As an initial step to mapping quantitative trait loci for species differences and adaptive radiation of insular endemics in Macaronesia, a genetic linkage map was constructed from an intergeneric backcross between Lactucosonchus webbii and Sonchus radicatus, core members of the tree lettuces in the Macaronesian Islands. A total of 152 amplified fragment length polymorphism markers were mapped into 10 major and 3 minor linkage groups for a total map length of 644 cM with an average distance of 4.53 cM for the 10 major groups. The genetic linkage map length is considerably less than the estimated, and this may reflect incomplete genomic coverage in the current study or reduced recombination, which is a common feature of maps for hybrids of divergent taxa. Segregation distortion occurred in 34% of the mapped markers, and they were located primarily in 4 linkage groups. Segregation distortion in the current BC(1) intergeneric population is slightly lower than average (40%) for BC(1) interspecific populations. This level of segregation distortion implies that unlike what we normally assume no to few reproductive barriers, oceanic island plant taxa do exhibit some degree of postmating reproductive isolation. (+info)Mutual feedbacks maintain both genetic and species diversity in a plant community. (4/15)
The forces that maintain genetic diversity among individuals and diversity among species are usually studied separately. Nevertheless, diversity at one of these levels may depend on the diversity at the other. We have combined observations of natural populations, quantitative genetics, and field experiments to show that genetic variation in the concentration of an allelopathic secondary compound in Brassica nigra is necessary for the coexistence of B. nigra and its competitor species. In addition, the diversity of competing species was required for the maintenance of genetic variation in the trait within B. nigra. Thus, conservation of species diversity may also necessitate maintenance of the processes that sustain the genetic diversity of each individual species.

(+info)"Sonchus" is a genus name that refers to a group of plants commonly known as sowthistles. These plants belong to the family Asteraceae and are found worldwide. While "Sonchus" itself is not a medical term, some species have been used in traditional medicine. For instance, the leaves of some Sonchus species have been used as a food source or for their supposed medicinal properties, such as being diuretic, expectorant, or anti-inflammatory. However, it's important to note that these uses are not supported by extensive scientific research and should not be considered medical advice. Always consult with a healthcare professional before starting any new treatment or therapy.
Rhabdoviridae is a family of negative-sense, single-stranded RNA viruses that include several important human and animal pathogens. The name "Rhabdoviridae" comes from the Greek word "rhabdos," meaning rod, which refers to the characteristic bullet shape of these virions.
The family Rhabdoviridae is divided into six genera: Vesiculovirus, Lyssavirus, Ephemerovirus, Novirhabdovirus, Cytorhabdovirus, and Sphericalvirus. The most well-known member of this family is the rabies virus, which belongs to the genus Lyssavirus.
Rhabdoviruses have a simple structure, consisting of an envelope surrounding a helical nucleocapsid that contains the RNA genome. The virions are typically 100-430 nm in length and 45-100 nm in diameter, with a central electron-dense core surrounded by a less dense matrix protein layer.
Rhabdoviruses infect a wide range of hosts, including mammals, birds, fish, reptiles, and insects. They typically cause acute infections characterized by fever, lethargy, and other nonspecific symptoms. In severe cases, rhabdovirus infections can lead to serious neurological disorders, such as encephalitis or meningitis, and can be fatal if left untreated.
Transmission of rhabdoviruses occurs through various routes, depending on the specific virus and host. For example, rabies virus is typically transmitted through the bite of an infected animal, while other rhabdoviruses may be spread through contact with contaminated bodily fluids or aerosols.
Prevention and control measures for rhabdovirus infections depend on the specific virus and host. For example, rabies vaccination is effective in preventing infection in humans and animals, while other rhabdoviruses may be controlled through quarantine measures, insect control, or antiviral therapy.
The term "Atlantic Islands" generally refers to the islands located in the Atlantic Ocean. However, there is no specific or official medical definition for this term. It may include various island groups such as:
* The Azores and Madeira (Portugal)
* The Canary Islands (Spain)
* Cape Verde Islands
* Bermuda
* The British Isles (UK)
In a medical context, the term might be used to describe health issues or characteristics specific to these island populations. For example, studies may examine the prevalence of certain genetic disorders, lifestyle diseases, or environmental health factors in Atlantic Island populations compared to mainland populations.
In the context of medicine and toxicology, protective agents are substances that provide protection against harmful or damaging effects of other substances. They can work in several ways, such as:
1. Binding to toxic substances: Protective agents can bind to toxic substances, rendering them inactive or less active, and preventing them from causing harm. For example, activated charcoal is sometimes used in the emergency treatment of certain types of poisoning because it can bind to certain toxins in the stomach and intestines and prevent their absorption into the body.
2. Increasing elimination: Protective agents can increase the elimination of toxic substances from the body, for example by promoting urinary or biliary excretion.
3. Reducing oxidative stress: Antioxidants are a type of protective agent that can reduce oxidative stress caused by free radicals and reactive oxygen species (ROS). These agents can protect cells and tissues from damage caused by oxidation.
4. Supporting organ function: Protective agents can support the function of organs that have been damaged by toxic substances, for example by improving blood flow or reducing inflammation.
Examples of protective agents include chelating agents, antidotes, free radical scavengers, and anti-inflammatory drugs.
A plant virus is not defined in medical terms, as viruses are typically considered within the context of living organisms and plants are not classified as such. However, I can provide a general virology definition for you:
Plant viruses are small infectious agents that consist of nucleic acid (DNA or RNA) enclosed in a protein coat. They infect various plant species, causing a wide range of symptoms and diseases, which can result in significant economic losses in agriculture and horticulture. Plant viruses lack the ability to replicate outside a host cell, and they rely on the host's metabolic machinery for their reproduction. They can be transmitted through various means, such as insect vectors, seeds, or mechanical contact.
