Homalium glandulosum Tagane & V. H. Nguyen, from Vu Quang National Park in northern Vietnam, is newly described. This species is characterized by distinct glands, often stalked, at the base of the lamina and along the margin of the stipules and bracteoles. Illustrations, DNA barcodes of the two regions of rbcL and matK, and a key to the species of Homalium in Vietnam are also provided.
Although, the Abaso section is widely accepted as an independent section, the taxonomic status of Populus mexicana (section Abaso) has not yet been resolved due to the limited availability markers and/or the lack of P. mexicana specimens in previous studies. Thirty-one poplar species that represent six sections of the Populus genus were sampled, and 23 single-copy nuclear DNA and 34 chloroplast...
The conditions required by rare species are often only approximately known. Monitoring such species over time can help refine management of their protected areas. We report population trends of a rare moth, the Dark Bordered Beauty Epione vespertaria (Linnaeus, 1767) (Lepidoptera: Geometridae) at its last known English site on a protected lowland heath, and those of its host-plant, Salix repens...
این مطالعه آنالیز فیلوژنتیکی داده های توالی های nrdna its برای 62 تاکسون شامل 55 گونه salix و دو گونه ی populus به عنوان برون گروه و توالی های trnl-f کلروپلاستی برای 14 گونه salix استفاده شد. آنالیز فیلوژنتیکی با استفاده از روشهای بیشینه ی صرفه جوئی (maximum parsimony) و bayesianانجام گرفت. فیلوژنی حاصل از توالی های nrdna its نشان داد که همه ی پنج زیرجنس رایج salix به استثنای زیرجنس مونوتیپیکl...
(Phytochemistry, 26, 2418 (1987)) Acylated Luteolin Glucosides from Salix gitgiana. MIzuo MIzuNo*, MAsAyA KATo, MuNEKAzu IINuMA, TosHIyuKI TANAKA, ' ARIKA KIMuRA, HIRoyosHI OHAsHI, HIDEKI SAKAi Besides apigenin and luteolin 7-glucoside, four novel glucosides acylated with acetic, trans-cinnamic, P-coumaric and ferulic acids, respectively were isolated from the leaves of Salix gitgiana (Salicace...
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...
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...
