جنس elymus از قبیله triticeae جزو گیاهان تک لپه ای، از راسته glumales ، تیره ی gramineae (poaceae)، می باشد. این جنس بزرگترین جنس قبیله triticeaeبوده و شامل حدود180 گونه علفی چندساله در جهان است. به دلیل خصوصیاتی چون؛ دایمی بودن، ارزش غذایی خوب، خوشخوراکی برای دام، مقاومت به خشکی و گرمای زیاد، مقاومت به شوری، توانایی تحمل خاک های فقیر و قلیایی و ریزوم دار بودن علاوه بر تولید علوفه، جهت حفاظت خا...
Elymus sibiricus as an important forage grass and gene pool for improving cereal crops, that is widely distributed in West and North China. Information on its genetic diversity and relationships is limited but necessary for germplasm collection, conservation and future breeding. Start Codon Targeted (SCoT) markers were used for studying the genetic diversity and relationships among 53 E. sibiri...
Pseudoroegneria spicata (Poaceae: Triticeae) is an abundant, allogamous species widely adapted to the temperate, semiarid steppe and open woodland regions of western North America. Amplified fragment length polymorphism (AFLP), model-based Bayesian clustering, and other methods of hypothesis testing were used to investigate genetic diversity and population structure among 565 P. spicata plants ...
BACKGROUND Previous cytological and single copy nuclear genes data suggested the St and Y genome in the StY-genomic Elymus species originated from different donors: the St from a diploid species in Pseudoroegneria and the Y from an unknown diploid species, which are now extinct or undiscovered. However, ITS data suggested that the Y and St genome shared the same progenitor although rather few S...
A total of 519 wild animals belonging to eleven species were collected during a two year study in a cutaneous leishmaniasis endemic area in Venezuela (La Matica, Lara State). The animals were captured in home-made Tomahawk-like traps baited with maize, bananas or other available local fruits, and parasites were isolated from 27 specimens. Two different species were found naturally infected with...
Theories based on competition for resources predict a monotonic negative relationship between population density and individual biomass in plant populations. They do not consider the role of facilitative interactions, which are known to be important in high stress environments. Using an individual-based 'zone-of-influence' model, we investigated the hypothesis that the balance between facilitat...
زیر گونه elymuslazicus subsp. attenuatiglumis که در مسافرت علمی به استان اردبیل و در مسیر خلخال به اسالم جمع آوری گردید، برای اولین بار از ایران گزارش می شود.
