Salix caprea is widely used in folk medicine for rheumatoid arthritis, malaria, various hemorrhages, gout, neuralgia and intestinal diseases as an antipyretic, analgesic, anti-inflammatory, antibacterial, hemostatic, sedative, and antihelminthic agent However, There are no critical reports available about anti diabetic potential of Salix caprea flowers. So anti diabetic effect of methanol extra...

Differences among populations in the intensity of sexual selection resulting from distinct genetic mating systems can lead to divergent morphological evolution and speciation. However, little is known about how genetic mating systems vary between populations and what factors may contribute to this variation. In this study, we compare the genetic mating systems of two geographically distinct pop...

Current taxonomy places all rust fungi that occur on willow (Salix spp.) in North America in one species complex, Melampsora epitea Thüm. Characteristics of M. epitea isolates from the Canadian arctic were compared to M. epitea isolates from temperate regions of North America. Sequences from internal transcribed spacer (ITS) regions of rDNA were obtained from urediniospores from rust-infected S...

The success of using Populus and Salix for phytoremediation has prompted further use of leachate as a combination of irrigation and fertilization for the trees. A common protocol for such efforts has been to utilize a limited number of readily-available genotypes with decades of deployment in other applications, such as fiber or windbreaks. However, it may be possible to increase phytoremediati...

miR1444s are functionally significant miRNAs targeting polyphenol oxidase (PPO) genes for cleavage. MIR1444 genes were reported only in Populus trichocarpa. Through the computational analysis of 215 RNA-seq data, four whole genome sequences of Salicaceae species and deep sequencing of six P. trichocarpa small RNA libraries, we investigated the origin and evolution history of MIR1444s. A total o...

Salix L. is the largest genus in the family Salicaceae (450 species). Several classifications have been published, but taxonomic subdivision has been under continuous revision. Our goal is to establish the phylogenetic structure of the genus using molecular data on all American willows, using three DNA markers. This complete phylogeny of American willows allows us to propose a biogeographic fra...

We investigated species divergence, present and past gene flow, levels of nucleotide polymorphism, and linkage disequilibrium in two willows from the plant genus Salix. Salix belongs together with Populus to the Salicaceae family; however, most population genetic studies of Salicaceae have been performed in Populus, the model genus in forest biology. Here we present a study on two closely relat...

Roles of the vegetation to mitigate the erosion of the stream bed or to facilitate the deposition of the fine sediments by the species of the aquatic plants were presented. Field investigation on the estimation of the change of the bed level and the estimation of the flow characteristics were performed. The results showed that Phragmites japonica has the mitigation function of 0.3m-0.4m of the ...
