We report the results of a study on the effectiveness of Cot filtration (CF) in the characterization of the gene space of bread wheat (Triticum aestivum L.), a large genome species (1C = 16,700 Mb) of tremendous agronomic importance. Using published Cot data as a guide, 2 genomic libraries for hexaploid wheat were constructed from the single-stranded DNA collected at Cot values > 1188 and 1639 ...
Protein electrophoretic profiles cast doubt upon the prevalent theory that the B genome of the polyploid wheats was derived from a species of Aegilops. They suggest, instead, that the wild tetraploid wheats comprise a complex, whose components were derived from various combinations of diploid Triticum types, which evidently include the B-genome type.
Aegilops tauschii Coss., the D genome donor of hexaploid wheat (Triticum aestivum L.), is most promising resource used to broaden genetic diversity wheat. Taxonomical studies have classified Ae. into two subspecies, ssp. and strangulata. However, molecular analysis revealed three distantly related lineages, TauL1, TauL2 TauL3. TauL1 TauL3 includes only tauschii, whereas both subspecies. This st...
تحقیق حاضر مبتنی بر مطالعه تاکسونومی 100 نمونه جمعیتی از گونه aegilops cylindrica جمع آوری شده از سرتاسر کشور و همچنین مطالعه نمونه های تیپ و نمونه های مربوط موجود در هرباریوم های موزه تاریخ طبیعی وین و برلین است. نتایج این مطالعه نشان داد که صفات ریخت شناختی نظیر: طول سنبله، طول سیخک، تعداد سنبلک ها در هر سنبله، حضور/غیبت کُرک روی سنبلک ها و محور در بین نمونه های جمعیتی مطالعه شده تنوع بالایی د...
A total of 37 original cDNA libraries and 9 derivative libraries enriched for rare sequences were produced from Chinese Spring wheat (Triticum aestivum L.), five other hexaploid wheat genotypes (Cheyenne, Brevor, TAM W101, BH1146, Butte 86), tetraploid durum wheat (T. turgidum L.), diploid wheat (T. monococcum L.), and two other diploid members of the grass tribe Triticeae (Aegilops speltoides ...
the quality traits of triticum dicoccoides ku-13441 (triticum turgidum l. var. dicoccoides (aabb, 2n= 4x= 28)) were analyzed by mixograph, and the results showed that t. dicoccoides ku-13441 had desirable qualities in gluten strength and flour stirring tolerance. subsequently, seventeen novel full-orf α-gliadin genes and thirty-five pseudogenes were cloned and sequenced from t. dicoccoides ku-1...
studies of postmeiotic chromosomes have been impeded by the thick exine of immature pollen grains. chromosome staining of immature and adult pollen grains through conven-tional acetocarmine procedure is tedious and often leads to unsatisfactory results. an acetocarmine stain, used in conjugation with carnoy’s solution as fixative for 72 hrs or until the chlorophyll-containing tissues of spike b...
