Wheat stem rust, caused by Puccinia graminis f. sp. tritici, is a re-emerging disease, posing threat to wheat production. In Spain, rust has been rarely detected since the 1970s, but infection was observed in fields 2018. We analysed six samples collected Rota, Cádiz province and one from Monteagudo del Castillo, Teruel province. All Rota were typed as race TKTTF, whereas sample field adjacent ...
Wheat stem rust, caused by Puccinia graminis f. sp. tritici, can cause severe yield losses on susceptible wheat varieties and cultivars. Although stem rust can be controlled by the use of genetic resistance, population dynamics of P. graminis f. sp. tritici can frequently lead to defeat of wheat stem rust resistance genes. P. graminis f. sp. tritici race TKTTF caused a severe epidemic in Ethiop...
Two cytologically stable wheat-Dasypyrum breviarisatatum addition lines, Y93-1-6-6 and Y93-1-A6-4, were identified by integrated molecular and cytogenetic techniques. C-banding and genomic in situ hybridization (GISH) showed that Y93-1-6-6 and Y93-1-A6-4 were different wheat-D. breviaristatum additions. A total of 51 markers (primer/enzyme combinations), including 6 PCR-based Landmark Unique Ge...
We combined the recently developed genotyping by sequencing (GBS) method with joint mapping (also known as nested association mapping) to dissect and understand the genetic architecture controlling stem rust resistance in wheat (Triticum aestivum). Ten stem rust resistant wheat varieties were crossed to the susceptible line LMPG-6 to generate F6 recombinant inbred lines. The recombinant inbred ...
Race TTKSK (or Ug99) of Puccinia graminis f. sp. tritici possesses virulence to several stem rust resistance genes commonly present in wheat cultivars grown worldwide. New variants detected in the race TTKSK lineage further broadened the virulence spectrum. The identification of sources of genetic resistance to race TTKSK and its relatives is necessary to enable the development and deployment o...
زمینه و هدف: microRNA (miRNA) دستة جدیدی از شاخصهای زیستیاند که در سطح سلولی مسیرهای پیامرسانی تغییرات ساختاری عملکردی قلبی درگیرند. همچنین تمرینات تناوبی شدید (HIIT) شامل وهلههای فعالیت ورزشی نسبتاً با مدت زمان کوتاه است دورههای بازیافت فعال یا غیرفعال یکدیگر جدا شدهاند، میتواند سبب بهبود آمادگی قلبی-تنفسی متغیرهای فیزیولوژیک متناظر آن افراد سالم شود. ازاینرو پژوهش حاضر نظر دارد اثر هشت...
