Development and refinement of methods to analyse differential gene expression has been essential in the progress of molecular biology. A novel approach called iGentifier is presented for profiling known and unknown transcriptomes, thus bypassing a major limitation in microarray analysis. The iGentifier technology combines elements of fragment display (e.g. Differential Display or RMDD) and tag ...
Barley powdery mildew, caused by the pathogen Blumeria graminis f. sp. hordei is an important disease of barley (Hordeum vulgare L.). The random amplified polymorphic DNA (RAPD) method was used to detect DNA polymorphism among 7 Pallas near-isogenic lines (NILs) carrying Mla3, Mla12, Mlk, Mlp, Mlat, Mlg and MlLa genes for resistance to B. graminis f. sp. hordei. From among 500 random 10-mer pri...
سفیدک پودری گندم (Blumeria graminis f. sp. tritici) در استانهای مازندران و گلستان یک بیماری مهم محسوب می شود و سالانه خسارت زیادی به محصول گندم وارد می کند. به منظور کنترل این بیماری از طریق استفاده از ارقام مقاوم ضروری است ابتدا پر آزاری جدایه‌های بیمارگر مشخص گردد. نمونه‌های بیماری از مزارع مختلف گندم دو استان در سال 1383 جمع آوری و پرآزاری یا ناپرآزاری بیمارگر با استفاده از 15 رقم و لاین افت...
Five accessions of Aegilops speltoides and 67 European wheat cultivars (winter and spring) originating from the Czech Republic, Germany, Poland, Russia, Slovakia, United Kingdom, and 4 non-European wheat cultivars from Brazil and the USA were examined with molecular Sequence Tagged Site (STS) markers for resistance genes to powdery mildew: Pm 1, Pm 2, Pm 3 and Pm 13. All markers gave clear, rep...
Fungal cereal pathogens, including Blumeria graminis f.sp. avenae, have the ability to adapt specific conditions, which in turn leads overcoming host resistance. An important aspect is standardized way of characterizing races and pathotypes pathogen. In presented work, for first time it was proposed use a unified letter code that allows describing B. avenae. The set 14 oat genotypes were used a...
