A plant genus of the family BRASSICACEAE. Member species are ornamentals grown for their numerous small white, yellow, pink, or purplish flowers.
A genus of polyhedral plant viruses of the family COMOVIRIDAE causing ringspots and spotting on leaves or sometimes symptomless infection. Transmission occurs by seeds, soil nematodes, or experimentally by mechanical inoculation. Tobacco ringspot virus is the type species.
Small, linear single-stranded RNA molecules functionally acting as molecular parasites of certain RNA plant viruses. Satellite RNAs exhibit four characteristic traits: (1) they require helper viruses to replicate; (2) they are unnecessary for the replication of helper viruses; (3) they are encapsidated in the coat protein of the helper virus; (4) they have no extensive sequence homology to the helper virus. Thus they differ from SATELLITE VIRUSES which encode their own coat protein, and from the genomic RNA; (=RNA, VIRAL); of satellite viruses. (From Maramorosch, Viroids and Satellites, 1991, p143)

DNA variation in the acidic chitinase locus (ChiA) region in Arabis gemmifera and its related species. (1/17)

We analyzed DNA variation at the acidic chitinase (ChiA) locus of Arabis gemmifera and among its eight related species. Nucleotide diversity (pi) of the entire locus in A. gemmifera was 0.0032, which was one third that of A. thaliana. In A. gemmifera, an excess of unique polymorphisms yielded significantly negative results with the tests of Tajima and Fu and Li. The McDonald and Kreitman test revealed that the ratio of nucleotide replacement to synonymous changes in A. gemmifera was significantly greater than those between A. gemmifera and A. glabra, A. gemmifera and A. griffithiana, A. gemmifera and A. korshinskyi, A. gemmifera and A. wallichii, and A. gemmifera and A. himalaica. These results indicated that the neutrality assumption, the equilibrium population assumption, or both, could not be applied to the ChiA locus of A. gemmifera. The small size and relative isolation of local subpopulations of A. gemmifera could explain the excess of unique polymorphisms and the high proportion of replacement changes. The specific sampling scheme of this study, where one strain each was sampled from each local subpopulation might also have led to an excess of singletons. Interspecific comparison among Arabidopsis, Arabis and Cardaminopsis species showed that Ka was always lower than Ks, providing evidence against the adaptive evolution of ChiA. However, Ka/Ks was greater between closely related species than between more distant related species. ChiA had a higher level of replacement divergence and a lower level of synonymous divergence compared than did Adh. We suggest that both the mutation rate at the nucleotide level and the selective constraints at the protein level are lower in ChiA than in Adh.  (+info)

Intra- and interspecific DNA variation and codon bias of the alcohol dehydrogenase (Adh) locus in Arabis and Arabidopsis species. (2/17)

Sequence variation at the alcohol dehydrogenase (Adh) locus was analyzed for six species each of the genera Arabis and Arabidopsis. Phylogenetic analysis showed that investigated species were grouped into three clusters, and the generic classification did not correspond to the clusterings. The results indicated that the genera could not be distinguished on the basis of the Adh variation. A significant difference in the ratio of silent to replacement sites was detected by MK test in two comparisons, with Arabidopsis thaliana polymorphism due to excess silent divergence. Silent changes were predominant in the evolution of the Adh locus in Arabis and Arabidopsis. To infer evolutionary significance of silent substitutions, codon bias was studied. The degree of codon bias of the Adh region was relatively constant over Arabis and Arabidopsis species. "Preferred" codons of A. thaliana were determined. No evidence of natural selection on codon change was detected in the Adh regions of A. thaliana and Arabis gemmifera.  (+info)

Multiple hybrid formation in natural populations: concerted evolution of the internal transcribed spacer of nuclear ribosomal DNA (ITS) in North American Arabis divaricarpa (Brassicaceae). (3/17)

DNA sequence variation of the internal transcribed spacer (ITS) region of nuclear ribosomal DNA from Arabis holboellii, A. drummondii, and its putative hybrid A. divaricarpa was analyzed to study hybrid speciation in a species system geographically covering nearly the entire North American continent. Based on molecular systematics the investigated species are better combined under the genus Boechera. Multiple intraindividual ITS copies were detected in numerous accessions of A. divaricarpa, and, to a minor extent, in the parental taxa. Comparative phylogenetic analysis demonstrates that reticulate evolution is common. Consequently, concerted evolution of ITS regions resulted in different types of ITS fragments not only in hybrid populations but also in one of the parental taxa, A. holboellii. Hybrid formation often occurred independently at different sites and at different times, which is reflected by ITS copies resampling the original parental sequence variation in different ways. Some biogeographic structuring of genetic diversity is apparent and mirrors postglacial migration routes. Hybridization, reticulation, and apomixis are assumed to be the major forces driving speciation processes in this species complex. Analysis of conserved regions and secondary structures of the ITS region provided no evidence that, in this system, hybrid ITS evolution is predominantly driven in a particular direction. However, two regions in the ITS1 and ITS2, respectively, show higher mutation rates than expected from outgroup comparisons. Strong evidence for the occurrence of apomixis in A. holboellii and A. divaricarpa has come from pollen size measurements and estimations of pollen quality, which favor the hypothesis that A. drummondii served as paternal hybridization partner more frequently than A. holboellii.  (+info)

Trimorphic DNA variation in the receptor-like protein kinase gene in the F18L15-130 region of the wild plant Arabidopsis thaliana. (4/17)

DNA variation in the F18L15-130 region, which contains a receptor-like protein kinase gene, was analyzed for the wild plants Arabidopsis thaliana and Arabis gemmifera. In A. thaliana, at least three divergent sequence types were observed (trimorphism), instead of two distinct sequence types (dimorphism) detected in most of other nuclear gene regions studied for this plant species. Intragenic recombinations among the divergent sequence types generated four recombinant sequence types, although pattern of intragenic recombinations was complex. The estimated nucleotide variation in A. thaliana was the highest (pi = 0.0226 and theta = 0.0228) among genes investigated in this plant so far. The high level of nucleotide variation is due to divergence among the three distinct sequence types, each of which has a low level of nucleotide variation. Tests of Tajima, and Fu and Li did not detected deviation from neutrality, except for replacement sites, for which significantly negative Fu and Li's test value was detected. These results suggest that the receptor-like protein kinase gene in this region is functional. Possible causes for the trimorphic pattern of DNA polymorphism was discussed.  (+info)

Pleistocene colonization of afro-alpine 'sky islands' by the arctic-alpine Arabis alpina. (5/17)

The afro-alpine region comprises the high mountains of Ethiopia and tropical East Africa, which represent biological 'sky islands' with high level of endemism. However, some primarily arctic-alpine plants also occur in the afro-alpine mountains. It has been suggested that these plants are Tertiary relicts, but a recent worldwide study of Arabis alpina suggests that this species colonized the region twice during the Pleistocene. Here we investigate the detailed colonization history of A. alpina in the afro-alpine region based on chloroplast DNA sequences from 11 mountain systems. The results confirm the twice-into-Africa scenario. The Asian lineage is confined to the mountains closest to the Arabian Peninsula, on opposite sides of the Rift Valley (Simen Mts and Gara Muleta in Ethiopia), suggesting long-distance dispersal of this lineage. The African lineage is divided into two phylogeographic groups with distinct geographic distribution. The observed pattern is consistent with isolation of the African lineage in at least two interglacial refugia, located on separated highlands, followed by range expansion in cooler period(s), when the afro-alpine habitat extended further down the mountains. Several long-distance dispersal events, also across the Rift Valley, are suggested by single haplotypes observed outside the area occupied by the phylogeographic groups they belonged to.  (+info)

Frequent long-distance plant colonization in the changing Arctic. (6/17)

The ability of species to track their ecological niche after climate change is a major source of uncertainty in predicting their future distribution. By analyzing DNA fingerprinting (amplified fragment-length polymorphism) of nine plant species, we show that long-distance colonization of a remote arctic archipelago, Svalbard, has occurred repeatedly and from several source regions. Propagules are likely carried by wind and drifting sea ice. The genetic effect of restricted colonization was strongly correlated with the temperature requirements of the species, indicating that establishment limits distribution more than dispersal. Thus, it may be appropriate to assume unlimited dispersal when predicting long-term range shifts in the Arctic.  (+info)

Arabis macdonaldiana is a species of flowering plant in the mustard family known by the common name MacDonalds rockcress. It is native to northern California and Oregon, where it grows on newly exposed, barren serpentine soils in openings in temperate coniferous forest habitat. It is a rare and endangered plant known from several sites in California and approximately two occurrences in Oregon, where it is threatened mainly by mining, particularly of nickel, which is one of several metals plentiful in the serpentine.[1] On September 29, 1978, this was the second plant to be federally listed as an endangered species.[1] This is a perennial herb growing one or more slender stems from a small, branching caudex, reaching 10 to 30 centimeters tall. There is a basal patch of leaves with edges lined in small, widely spaced teeth which are sometimes tipped with spines. The leaves may lack teeth and have wavy margins. There may also be a few smaller leaves along the stem. The top of the stem forms an ...

ARABIS KOEHLERI SEEDS (Koehlers Rock Cress) - Plant World Seeds. This very rare, tough, tufted endemic lives only on a few dry hills, high above the rushing Umpqua River on the Pacific coast of Oregon. Cruciform flowers of bright purple open on compact, rounded shrubby domes which cling tenaciously to the rocky outcrops. In 2001, to reduce chances of extinction, researchers grew hundreds of plants in the Berry Botanic Garden greenhouse using seeds collected from the wild. During the autumn rains, researchers battled the slippery slopes and clung to the steep cliffs to place plants and directly sow seeds into appropriate habitat near existing Koehlers rockcress plants. Very few seeds available from cultivated plants.

Phylogenetic trees constructed from the conserved genes of the seven A. thaliana and Arabis alpina mitogenomes (Table 1) show that four East Asian Arabidopsis including 180404IB4 were clustered with the Col-0 (USA) with high supportive values and Ler-0 (Germany) and C-24 (Tanzania) were clustered in an independent clade (Fig. 1B). It is different from the phylogenetic tree constructed from the complete chloroplast genomes, displaying the intraspecific topology of the six A. thaliana ecotypes except for C-24 with high supportive values (Park et al., 2020a). It might be caused by the low coverage of the 30 conserved genes (6.98%) against the complete mitogenome in comparison to that of the chloroplast genomes. To improve the resolution of phylogenetic analysis using mitogenomes, more conserved areas except genic regions should be rescued and addition mitogenomes of East Asian A. thaliana are needed to be assembled to investigate their phylogenetic relationship.

The pathophysiologic mechanism underlying neuropathic pain may differ depending on the site of injury. Previous studies have demonstrated differences in behavioral responses to the more peripheral injury of partial sciatic nerve ligation (PSL) compared with the more proximal SNL model.4-6 Although both models involve direct injury and insertion of a foreign body (suture) around the nerve, the SNL has been shown to produce a more profound mechanical hypersensitivity.5 There are differences in sympathetic fiber growth after the different injuries, which may play a role in the differential behavioral responses.6,7 Furthermore, the dependence of the sympathetic growth is influenced by the growth factor production induced by the injury. The SNL model with a more proximal injury is different in that it is more uniform with all fibers in the L5-L6 nerve distribution being affected. This may deprive the cell body in dorsal root ganglia of a greater amount of the nerve axon, possibly reducing expression ...

The Arabis class was the third, and largest, of the five sub-classes of minesweeping sloops completed under the Emergency War Programme for the Royal Navy in World War I. They were part of the larger Flower Class shipbuilding project, which were also referred to as the Cabbage Class, or Herbaceous Borders. The ships were also used outside their minesweeping duties as patrol vessels, tugs, and personnel and cargo transports. The design for the Arabis class was made at the end of 1914. All 36 British vessels were ordered in July 1915, and were built in three batches, averaging 12 vessels. A further 8 vessels were later built in British shipyards for the French Navy. The design was highly appealing, as most shipyards were capable of building them, and construction could be completed in five months. Like the preceding Acacia and Azalea class sloops, these were single-screw Fleet Sweeping Vessels (Sloops) with triple hulls at the bows to give extra protection against loss when working. HMS ...

just below the pass. There are many good places to camp and fish in the lower valley before a strenuous climb up the headwall. The North Fork Trailhead is located 4.5 miles east of Independence Pass on Highway 82 between Aspen and Leadville, just far enough away from each to be overlooked. Visitors will enjoy lighter crowds and stunning alpine landscapes on the North Fork Trail:. The trail begins on a flat road bed that narrows up to a stream and the Mount Massive Wilderness Boundary (.71 miles : 11,018). Hop the stream and continue on mild grades between thin bands of timber and the North Fork of Lake Creek. It levels from 1.3 - 2.4 miles across broad meadows under steep, open slopes ideal for glassing wildlife. The trail weaves through willow leading to the west branch of the creek, which youll cross (right) and rise up a subtle ridge between branches of the North Fork (2.4 miles : 11,540). Note that after a brief time the route will follow the east branch up to the pass.. Grades steepen ...
Within a population, the pseudogenization of a gene does not happen instantaneously. Rather, after a disruptive mutation occurs, the alleles at the locus undergo a fixation process. Depending on the outcome, such a mutation is either fixed or lost. Thus, every gene loss goes through two stages: a polymorphic stage in the contemporary population subject to evolutionary forces; and a fixed stage freed from selective pressure. The fixed mutation becomes the base substitution in the species under study relative to the other and is identified through comparison of the genomes of two species. By comparing the human and the mouse genomes, we identify 76 fixed unitary pseudogenes. In addition, we identify 11 human genes with pseudogenic alleles, whose disruptive mutations include nonsense mutations and frameshifts. Our identification of polymorphic pseudogenes is by no means comprehensive as we search in the reference genome sequence for only the loci that are associated with both CDS disruptions and ...
