Stable resistance to infection with Wheat streak mosaic virus (WSMV) can be evolved de novo in selfing bread wheat lines subjected to cycles of WSMV inoculation and selection of best-performing plants or tillers. To learn whether this phenomenon might be applied to evolve resistance de novo to pathogens unrelated to WSMV, we examined the responses to leaf rust of succeeding generations of the r...
Diseases can greatly lower wheat yield and grain quality. Leaf rust, Stagnospora (Septoria) glume blotch, Septoria leaf blotch, and powdery mildew have historically been the most damaging diseases on wheat in Alabama. Stripe rust has recently emerged in the Deep South as a very destructive disease of wheat. Field cropping history, cultivar selection, and weather patterns all have a tremendous i...
Over 100 genes of resistance to rust fungi: Puccinia recondita f. sp. tritici, (47 Lr - leaf rust genes), P. striiformis (18 Yr - yellow rust genes) and P. graminis f. sp. tritici (41 Sr - stripe rust genes) have been identified in wheat (Triticum aestivum L.) and its wild relatives according to recent papers. Sixteen Lr resistance genes have been mapped using restriction fragments length polym...
Introduction Rust diseases of wheat are among the oldest plant diseases known to humans. Early literature on wheat cultivation mentions these devastating diseases and their ability to destroy entire wheat crops. Since rust discovery, numerous studies have been conducted on the life cycles of rust pathogens and their management. The information gained from these studies has enabled us to develop...
گندم یکی از منابع غنی انرژی در تغذیه انسان ها محسوب می شود. این گیاه هر ساله مورد تهاجم آفات و بیماری ها قرار می گیرد. از مهم ترین بیماری های قارچی گندم، زنگ زرد (stripe rust) می باشد.این تحقیق به منظور بررسی مقاومت شش رقم گندم نان زمستانه شامل زرین، الوند، پیشگام، اروم، زارع و میهن به بیماری زنگ زرد در دو آزمایش مجزای مزرعه ای در مزرعه ایستگاه تحقیقاتی میاندوآب در استان آذربایجان غربی در سال ز...
QTL mapping of adult plant resistance to stripe rust in the Fundulea 900 × Thatcher RIL population | Xiaocui Yan, Huimin Zheng, Peipei Zhang, Gebrewahid Takele Weldu, Zaifeng Li, Daqun Liu Agricultural Journals
A study was conducted to assess the durable resistance in a near isogenic line of spring wheat (Triticum aestivalis L.), possessing resistance gene Yr-18 to some isolates (race specific resistance) of stripe rust (Puccinia striiformis f. sp. tritici), namely Thatcher Yr-18 and durable resistance of an cultivar of spring wheat to all isolates of stripe rust (race non- specific resistance), namel...
We report here the release of four germplasm lines of hard red spring (HRS) wheat (T. aestivum L.) [Yecora Rojo Yr36– Gpc-B1 (Reg. no. GP-793, PI 638740), Yecora Rojo Lr47 (Reg. no. GP-791, PI 638738), Kern Lr47 (Reg. no. GP-792, PI 638739), and Anza Lr37/Yr17/Sr38 (Reg. no. GP-795, PI 638742)] and one durum wheat (T. turgidum L.) [UC1113 Yr36– Gpc-B1 (Reg. no. GP-794, PI 638741)], isogenic for...
Stripe rust (Puccinia striiformis f.sp. tritici) is the most devastating disease of wheat (Triticum aestivum L.) accounting huge economical losses to the industry worldwide. HD 2329 was a widely grown wheat cultivar which had become highly susceptible to stripe rust and was used to understand the biochemical aspects of the host pathogen interaction through characterization of superoxide dismuta...
Stripe rust is a devastating disease in wheat that causes substantial yield loss around the world. The most effective strategy for mitigating to develop resistant cultivars. wild relatives of are good sources resistance fungal pathogens. Here, we used genome-wide association study (GWAS) identify loci associated with stripe (causal agent: Puccinia striiformis f. sp. tritici) emmer (Triticum dic...
