Isoenzyme variation and genetic relationships between Elymus repens, E. hispidus and E. ×mucronatus (Triticeae, Poaceae)
Polyacrylamide gel electrophoresis (PAGE) was employed to examine the variation of ten isoenzyme markers in an attempt to assess the systematic and genetic relationships between Elymus repens, E. hispidus and their hybrid E. ×mucronatus. It was found that the hybrid shared most isoenzyme profiles and isoforms of its parents and high genetic affinity among the studied taxa was revealed. The isoe...
متن کاملthe speech act of advice and the introvert/extrovert distinction among iranian efl university students
the aim of this study is to examine the difference between the introverts and extroverts in preferred advice-giving style. furthermore, it explores the difference between l1 (persian) and l2 (english) regarding the giving of advice for the extroverts and introverts separately. it investigates whether an extrovert or introvert gives advice in the same manner in his l1 (persian) and l2 (english) ...
Phylogenetic relationships and reticulation among Asian Elymus (Poaceae) allotetraploids: analyses of three nuclear gene trees.
This phylogenetic study focuses on a subset of the species in Elymus-specifically, the endemic Asian tetraploids presumed to combine the St genome from Pseudoroegneria with the Y genome from an unknown donor. The primary goals were to (1) determine whether the St and Y genomes are derived from phylogenetically distinct donors; (2) identify the closest relative, and potentially the likely donor,...
متن کاملAllopolyploids of the Genus Elymus (Triticeae, Poaceae): a Phylogenetic Perspective
The wheat tribe, Triticeae, includes many genomically distinct polyploid taxa. Elymus is an entirely allopolyploid genus, with all species containing the St genome of Pseudoroegneria. The St genome may be combined with one or more distinct genomes representing multiple, diverse diploid donors from throughout the tribe. This study includes a simultaneous phylogenetic analysis of new and previous...
متن کاملPhylogenetic analysis of Elymus (Poaceae) in western China.
Elymus L. is often planted in temperate and subtropical regions as forage. Species in the genus have 5 allopolyploid genomes that are found in the grass tribe Triticeae. To determine the phylogenetic relationships in Elymus species from western China, we estimated phylogenetic trees using sequences from the nuclear ribosomal internal transcribed spacer and non-coding chloroplast DNA sequences f...
