Within-population genetic structure and clonal diversity of a threatened endemic metallophyte, Viola calaminaria (Violaceae).
We studied the within-population genetic structure and the clonality extent of Viola calaminaria, a rare endemic species of calamine soils, by means of RAPD markers in two populations (one recent and one ancient) with expected harsh and heterogeneous heavy-metal stress. At a very local scale (0.2-3 m), clonal propagation was detected in both populations, but the levels of clonal diversity were ...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Alteration of Sexual Reproduction and Genetic Diversity in the Kelp Species Laminaria digitata at the Southern Limit of Its Range
Adaptation to marginal habitats at species range-limits has often been associated with parthenogenetic reproduction in terrestrial animals and plants. Laboratory observations have shown that brown algae exhibit a high propensity for parthenogenesis by various mechanisms. The kelp Laminaria digitata is an important component of the ecosystem in Northern European rocky intertidal habitats. We stu...
متن کاملPharmacognostic Research on Viola Declinata Waldst. Et Kit. (violaceae)
In order to continue our previous studies on some Viola species from Romania, we have analysed for the first time some active principles from aerial parts of V. declinata Waldst. et Kit. We have performed gravimetric methods for saponins and mucilages, and spectrophotometric determinations and HPLC analysis of carotenoids. We established the content in saponins (4.40%), mucilages (10.26%), and ...
متن کاملEvaluation of Genetic Diversity in Iranian Violet (Viola spp) Populations Using Morphological and RAPD Molecular Markers
Recognition of genetic reserves and desirable genes is the basis of breeding programs. So far, in Iran, due to the lack of recognition of genetic resources, a considerable breeding program has not been done on native plants. The study of the genetic diversity of violets as a native plant with ornamental and medicinal uses is the great importance in advancing the breeding goals of this plant. So...
