×Kengdoroegneria, nothogen. nov., and new nomenclatural combinations in Triticeae (Poaceae)

Allopolyploids 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...

یادداشت‌هایی 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...

Phylogenetic-based nomenclatural proposals for Ophiocordycipitaceae (Hypocreales) with new combinations in Tolypocladium

Ophiocordycipitaceae is a diverse family comprising ecologically, economically, medicinally, and culturally important fungi. The family was recognized due to the polyphyly of the genus Cordyceps and the broad diversity of the mostly arthropod-pathogenic lineages of Hypocreales. The other two cordyceps-like families, Cordycipitaceae and Clavicipitaceae, will be revised taxonomically elsewhere. H...

Characterization of genome in tetraploid StY Elymus (Triticeae: Poaceae) species using Sequential FISH and GISH

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...
