Plant culture: thirteen seasonal pieces. February--constructing a corymb. (1/23)
According to Robert Graves' mythological interpretation of the seasonal cycle, February is associated with the rowan tree. Corymb is the systematic name for the rowan inflorescence that produces the distinctive group of orange berries. The corymb, a gently domed cluster, is related to a panicle and an anthela, differing from them in the extent of upgrowth of the inflorescence branches. Soon, molecular biology will provide a gene-driven description of each inflorescence structure. This advance illustrates the progress of science: previous issues of inflorescence classification are not resolved, but a new system, reflecting the availability of new technology, is established. The artist and poet William Blake remarked that it is better to invent a system, than be enslaved by that of another. He also railed against science for its improper restriction to the imagination. (+info)Breeding systems and continuing evolution in the endemic Sorbus taxa on Arran. (2/23)
The Arran whitebeams Sorbus arranensis and S. pseudofennica are two endemic woody plant taxa that have evolved on Arran through hybridisation. S. arranensis is a triploid hybrid between the widespread diploid S. aucuparia and the rare tetraploid S. rupicola. S. pseudofennica is a tetraploid formed by crossing between S. arranensis and S. aucuparia. In order to determine the mating systems of the two endemic species six maternal trees of each taxon together with 10-12 of their seed offspring were scored for their phenotype at three microsatellite loci and one nuclear intron locus. All seeds of S. arranensis were identical in phenotype to their maternal parents. In S. pseudofennica, 17.5% of all seeds differed in marker phenotype from their maternal parent. The proportion of seed with nonmaternal phenotypes varied significantly among maternal trees of S. pseudofennica. The results suggest that the triploid S. arranensis is an obligate apomict, whereas the tetraploid S. pseudofennica is a facultative apomict. Molecular marker analysis of three trees from Arran with an unusual leaf morphology indicates that they are the product of sexual reproduction by S. pseudofennica, and may originate from hybridisation with S. aucuparia. This research demonstrates that the Sorbus taxa on Arran are participants in an active evolutionary process generating novel biodiversity. Conservation programmes for these taxa should aim to preserve this evolutionary process rather than the individual taxonomic entities that it produces. (+info)Vascular relaxation by the methanol extract of Sorbus cortex via NO-cGMP pathway. (3/23)
The methanol extract of Sorbus commixta cortex (MSC) induced relaxation of the phenylephrine-precontracted aorta in a dose-dependent manner, which was disappeared by removal of functional endothelium. Pretreatment of the aortic tissues with N(G)-nitro-L-arginine methyl ester (L-NAME), methylene blue, or 1H-[1,2,4]-oxadiazole-[4,3-alpha]-quinoxalin-1-one (ODQ) inhibited the vascular relaxation induced by MSC. MSC-induced vascular relaxations were also markedly attenuated by addition of verapamil or diltiazem, while the relaxant effect of MSC was not blocked by pretreatment with indomethacine, glibenclamide, tetraethylammonium (TEA), atropine, or propranolol, respectively. Incubation of endothelium-intact carotid arteries or of human umbilical vein endothelial cells (HUVECs) with MSC increased the production of guanosine 3',5'-cyclic monophosphate (cGMP). Moreover, MSC-induced cGMP production was effect was blocked by pretreatment with L-NAME or ODQ. These results suggest that MSC dilates vascular smooth muscle via endothelium-dependent nitric oxide-cGMP signaling pathway, possible involvement of L-type Ca(2+) channel. (+info)Effect of methanol extract of Sorbus cortex in a rat model of L-NAME-induced atherosclerosis. (4/23)
Chronic inhibition of nitric oxide (NO) synthesis by administration of high dose of N(G)-nitro-L-arginine methylester (L-NAME) induces vascular inflammation and subsequent atherosclerosis. We aimed to investigate whether the methanol extract of Sorbus commixta cortex (MSC) is able to prevent inflammatory process in a rat model of L-NAME-induced atherosclerosis. Chronic treatment with low or high doses of MSC prevented the L-NAME-induced increase in monocyte chemoattractant protein-1 (MCP-1) and nuclear factor-kappaB (NF-kappaB) p65 expressions as well as adhesion molecules including intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1), and E-selectin in aorta. In addition, increased endothelin-1 (ET-1) and angiotensin converting enzyme (ACE) expressions and decreased endothelial cell NO synthase (ecNOS) expression in aorta from L-NAME treated group was reversed by treatment with MSC. From the histological examination, aortic segment from the L-NAME-treated rats revealed a thickening of intima and media, which was ameliorated by treatment with MSC. In conclusion, our results indicate that MSC can prevent atherosclerosis by inhibiting vascular over-expressions of vasoactive materials, pro-inflammatory transcription factor, and adhesion molecules and by augmenting ecNOS in chronic L-NAME-treated rat model. (+info)Anti-atherogenic effects of the methanol extract of Sorbus cortex in atherogenic-diet rats. (5/23)
The present study was designed to examine whether the methanol extract of Sorbus commixta cortex (MSC) could prevent the development of atherosclerosis through regulating the vascular nitric oxide (NO) and endothelin-1 (ET-1) systems in atherogenic-diet rats. Our findings show that aortic NO production as well as endothelial nitric oxide synthase (ecNOS) expression was significantly decreased in atherogenic-diet rats compared with those in the control group. Aortic ET-1 expression was augmented in rats fed an atherogenic-diet while NF-kappaB p65 was upregulated. Treatment of atherogenic-diet rats with either low (100 mg/kg/d) or high (200 mg/kg/d) doses of MSC led not only to significant increases in the aortic NOS/NO system, but also to decreases in aortic ET-1 expression. The aortic expression level of NF-kappaB p65 was also attenuated in atherogenic-diet rats by chronic treatment with low or high doses of MSC. Atherogenic-diet induced increases in the expression of adhesion molecules including intercellular adhesion molecules-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin were markedly decreased by treatment with MSC. From the histopathological examination, MSC treatment was shown to lessen the thickening noted in the aortic intima and media of the atherogenic-diet rats. These results suggest that MSC affects the atherogenic process via the suppression of proinflammatory and adhesion molecules in atherogenic-diet rats, which may be, at least in part, causally related with the regulation of vasoactive systems such as the NO and ET-1 systems. (+info)Notes on a plant parasite fungus in Portugal: Gymnosporangium cornutum. (6/23)
A rust fungus identified as Gymnosporangium cornutum was found on Sorbus aucuparia in Serra da Estrela (Manteigas), and the disease was severe at that location. Despite the abundance and worldwide occurrence of the genus Gymnosporangium, studies in Portugal are still limited. (+info)A novel, multipartite, negative-strand RNA virus is associated with the ringspot disease of European mountain ash (Sorbus aucuparia L.). (7/23)
Four RNAs from a new plant-pathogenic virus, which we have tentatively named European mountain ash ringspot-associated virus (EMARAV), were identified and sequenced completely. All four viral RNAs could be detected in previous double-stranded RNA preparations. RNA 1 (7040 nt) encodes a protein with similarity to the RNA-dependent RNA polymerase of different members of the Bunyaviridae, a family containing five genera with viruses infecting invertebrates, vertebrates and plants. RNA 2 (2335 nt) encodes a 75 kDa protein containing a conserved motif of the glycoprotein precursor of the genus Phlebovirus. Immunological detection indicated the presence of proteins with the expected size of the precursor and one of its processing products. The amino acid sequence of protein p3 (35 kDa) encoded by RNA 3 shows similarities to a putative nucleocapsid protein of two still unclassified plant viruses. The fourth viral RNA encodes a 27 kDa protein that has no significant homology to any known protein. As is typical for members of the family Bunyaviridae, the 5' and 3' ends of all viral RNAs are complementary, which allows the RNA to form a panhandle structure. Comparison of these sequences demonstrates a conserved terminal part of 13 nt, similar to that of the bunyaviral genus Orthobunyavirus. Despite the high agreement of the EMARAV genome with several characteristics of the family Bunyaviridae, there are a few features that make it difficult to allocate the virus to this group. It is therefore more likely that this plant pathogen belongs to a novel virus genus. (+info)Aphids do not attend to leaf colour as visual signal, but to the handicap of reproductive investment. (8/23)
The evolution of visual warning signals is well known in animals but has received scant attention in plants. The coevolutionary hypothesis is the most influential hypothesis on warning signals in plants proposing that red and yellow leaf colours in autumn signal defensive strength to herbivores. So far, evidence in support of the hypothesis, which assumes a coevolutionary origin of autumnal leaf colours, is correlative and open to alternative explanations. We therefore tested the coevolutionary hypothesis experimentally by colouring the leaves either red or green of same-aged mountain ash (Sorbus aucuparia) individuals. We monitored the response of winged aphids to leaf colour using insect glue on branches with natural and artificial leaf colours in each individual. In contrast to the prediction of the coevolutionary hypothesis, aphid numbers did not differ between the individuals with artificial green or artificial red leaves. Likewise, at the within-plant level, aphids did not colonize branches with natural green leaves preferentially. However, we suggest that plants emitted warning signals because aphids colonized the hosts non-randomly. We found a strong positive correlation between aphid numbers and fruit production, suggesting an allocation trade-off between investment in plant defence and reproduction. Our study demonstrates that aphids use warning signals or cues in host selection, probably volatiles, but that they did not use leaf colour. (+info)"Sorbus" is a term used in botanical nomenclature, not in medical definitions. It refers to a genus of trees and shrubs in the rose family (Rosaceae), which includes plants like rowans, whitebeams, and serviceberries. These plants have various medicinal uses, with their fruits, barks, and leaves containing compounds that have been used in traditional medicine to treat conditions such as diarrhea, fever, and skin irritations. However, it is essential to note that the medical application of these plants should be based on scientific research and under the guidance of a healthcare professional, as some parts of these plants may also contain toxic compounds.
Self-fertilization is not a term typically used in human or animal medicine, but it is a concept in botany. It refers to the fertilization of an ovule (a structure in plants that develops into a seed after fertilization) with pollen from the same plant. This can occur in hermaphroditic flowers, which have both male and female reproductive organs. Self-fertilization can increase genetic similarity within a population of plants, which can have implications for their evolution and survival.
