The wheat leaf-rust resistance gene Lr21 was first identified in an Iranian accession of goatgrass, Aegilops tauschii Coss., the D-genome donor of hexaploid bread wheat, and was introgressed into modern wheat cultivars by breeding. To elucidate the origin of the gene, we analyzed sequences of Lr21 and lr21 alleles from 24 wheat cultivars and 25 accessions of Ae. tauschii collected along the Cas...
Bread wheat (Triticum aestivum, AABBDD) is an allohexaploid species derived from two rounds of interspecific hybridizations. A high-quality genome sequence assembly of diploid Aegilops tauschii, the donor of the wheat D genome, will provide a useful platform to study polyploid wheat evolution. A combined approach of BAC pooling and next-generation sequencing technology was employed to sequence ...
Adaptation to edaphic stress may have a key role in plant species range expansion. Aegilops tauschii Coss., the common wheat's D-genome progenitor native to the Transcaucasus-Middle East region, is a good model to study the relationships between soil salinity and plant distributions: one of its intraspecific sublineages, TauL1b, drove the long-distance eastward expansion of this species range r...
In higher plants, seed storage proteins (SSPs) are frequently expressed from complex gene families, and allelic variation of SSP genes often affects the quality traits of crops. In common wheat, the Glu-D1 locus, encoding 1Dx and 1Dy SSPs, has multiple alleles. The Glu-D1d allele frequently confers superior end-use qualities to commercial wheat varieties. Here, we studied the haplotype structur...
به منظور بررسی میزان جذب فسفر و آهن و برخی شاخص‌های فیزیولوژیک در گندم نان (رقم سرداری) و گونههای وحشی اجدادی آن جهت گزینش‌های بهنژادی و انتقال ژن، آزمایش فاکتوریلی در قالب طرح بلوک‌های کامل تصادفی اجرا شد. در این آزمایش، خصوصیات فیزیولوژیک و میزان جذب فسفر و آهن گندم نان و گونه های اجدادی آن (boeoticumTriticum ، Aegilops speltoides، Triticum diccocoides وAegilops tauschii) تحت تأثیر عامل ک...
Protein disulphide isomerase (PDI) is an oxidoreductase enzyme abundant in the endoplasmic reticulum (ER). In plants, PDIs have been shown to assist the folding and deposition of seed storage proteins during the biogenesis of protein bodies in the endosperm. Cloning and characterization of the complete set of genes encoding PDI and PDI like proteins in bread wheat (Triticum aestivum cv. Chinese...
