Relationships among Agropyron, Dasypyrum and Lophopyrum (Triticeae: Poaceae) viewed from isoenzyme variation of esterase, peroxidase and acid phosphatase
Isoenzyme variation of esterase, peroxidase and acid phosphatase was examined in individual plants from natural populations of A. cristatum, D. villosum and L. elongatum. Four indices of phenotypic similarity (SI, S, D, Ih) were calculated in an attempt to assess relationships among the taxa studied. All indices have their lowest estimates in the comparison between L. elongatum and D. villosum....
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 کاملیادداشتهایی بر Aegilops cylindrica (Triticeae, Poaceae) در ایران
تحقیق حاضر مبتنی بر مطالعه تاکسونومی 100 نمونه جمعیتی از گونه Aegilops cylindrica جمع‌آوری شده از سرتاسر کشور و همچنین مطالعه نمونه‌های تیپ و نمونه‌های مربوط موجود در هرباریوم‌های موزه تاریخ طبیعی وین و برلین است. نتایج این مطالعه نشان داد که صفات ریخت‌شناختی نظیر: طول سنبله، طول سیخک، تعداد سنبلک‌ها در هر سنبله، حضور/غیبت کُرک روی سنبلک‌ها و محور در بین نمونه‌های جمعیتی مطالعه شده تنوع بالایی د...
متن کاملDiversification of the P genome among Agropyron Gaertn. (Poaceae) species detected by FISH
The genomes of five Agropyron Gaertner, 1770 species were characterized using all potential di- or trinucleotide simple sequence repeat (SSR) motifs and four satellite DNA repeats as fluorescence in situ hybridization (FISH) probes. The sites of 5S and 45S rDNA were relatively conserved among the diploid and tetraploid species. A number of sites for the dinucleotide SSRs AC, AG, and pSc119.2 wa...
متن کاملIntergenomic Rearrangements after Polyploidization of Kengyilia thoroldiana (Poaceae: Triticeae) Affected by Environmental Factors
Polyploidization is a major evolutionary process. Approximately 70-75% species of Triticeae (Poaceae) are polyploids, involving 23 genomes. To investigate intergenomic rearrangements after polyploidization of Triticeae species and to determine the effects of environmental factors on them, nine populations of a typical polyploid Triticeae species, Kengyilia thoroldiana (Keng) J.L.Yang et al. (2n...
