Abstract:
... Stripe rust, caused by Puccinia striiformis f. sp. tritici, is an important disease of wheat. In this study, 1,567 isolates collected from the United States from 2013 to 2017 were tested for virulence on 18 wheat Yr single-gene lines to differentiate races. In total, 72 races, including 20 new, were identified, and their frequencies in different years and different epidemiological regions were det ...

Abstract:
... Wheat production is often affected by different types of rust diseases, in which stripe rust is triggered by a fungal pathogen, Puccinia striiformis f. sp. tritici (Pst), and remains the biggest challenge to the plant breeders and farmer community. Nevertheless, pathogens exploit its effector proteins for altering the susceptibility (S) genes in the host plant, rendering host defense inactivated. ...

Abstract:
... Stripe rust (caused by Puccinia striiformis f. sp. tritici) is one of the most severe diseases for wheat production. An important method to improve the stripe rust resistance of wheat is to introduce resistance genes from related species into the wheat genome. The 1RS.1BL wheat–rye translocation from Petkus rye has contributed substantially to wheat resistance breeding worldwide. However, given th ...

Abstract:
... The worldwide spread of wheat yellow rust lineage PstS1/S2 adapted to higher temperatures prompted us to investigate how diverse temperature responses of this lineage are in the Middle East, where diversity was previously observed within this lineage for pathotypes and genotypes. Here we highlight the diversity of response to temperature within a PstS1/S2 population. Twenty‐six isolates from eight ...

Abstract:
... Numerous studies using a combination of confocal microscopic- and pharmacological-based approaches have demonstrated that the actin cytoskeleton dynamically responds to pathogen infection. Here, we observed that phalloidin treatment induced actin nucleation, resulting in enhanced resistance of wheat against the stripe rust pathogen Puccinia striiformis f. sp. tritici (Pst). To define the mechanism ...

Abstract:
... Many Berberis species have been identified as alternate hosts for Puccinia striiformis f. sp. tritici. Importantly, susceptible Berberis species are determined to play an important role in the occurrence of sexual reproduction, generation of new races of the rust pathogen. However, little is known about Mahonia serving as alternate hosts for P. striiformis f. sp. tritici and their role to commence ...

Abstract:
... Wheat gene Yr39 confers durable high-temperature adult-plant (HTAP) resistance to stripe rust caused by Puccinia striiformis f. sp. tritici, one of the most destructive diseases of wheat worldwide. The objective of this study was to transfer Yr39 into four Chinese elite wheat cultivars. Backcross inbred line populations were developed from four Chinese wheat cultivars Chuanmai 42 (CM42), Bainong A ...

Abstract:
... Sugar efflux from host plants is essential for pathogen survival and proliferation. Sugar transporter‐mediated redistribution of host sugar contributes to the outcomes of plant–pathogen interactions. However, few studies have focused on how sugar translocation is strategically manipulated during host colonization. To elucidate this question, the wheat sugar transport protein (STP) TaSTP3 respondin ...
... One hundred and five (105) bread wheat (Triticum aestivum L.) genotypes, including five commercial checks, were screened for stripe rust resistance at seedling and adult plant stages. Seedlings grown under controlled conditions were screened for disease resistance after 12 days concerning disease incidence percentage after inoculation. K-means cluster analysis divided the genotypes into five diffe ...

MP‐15, NSL 540708 MAP) composed of a cross between the soft white common winter wheat (Triticum aestivum L. subsp. aestivum) ‘Brundage’ (PI 599193) and the soft white club winter wheat (T. aestivum L. subsp. compactum) ‘Coda’ (PI 594372) was developed to maximize diversity within the soft white market class. The population comprises 268 F₆:₇ lines developed through s ...

Abstract:
... Wheat crops are frequently devastated by pandemic stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). Here, we identify and characterize a wheat receptor-like cytoplasmic kinase gene, TaPsIPK1, that confers susceptibility to this pathogen. PsSpg1, a secreted fungal effector vital for Pst virulence, can bind TaPsIPK1, enhance its kinase activity, and promote its nuclear localization, w ...

Abstract:
... Yellow (YR) and leaf (LR) rusts caused by Puccinia striiformis f. sp. tritici (Pst) and Puccinia triticina, respectively, are of utmost importance to wheat producers because of their qualitative and quantitative effect on yield. The search for new loci resistant to both rusts is an ongoing challenge faced by plant breeders and pathologists. Our investigation was conducted on a subset of 168 pre-br ...

Abstract:
... Invasions of new races can have contrasting consequences on populations of Puccinia striiformis f. sp. tritici, causing yellow rust of wheat. For example, the emergence of PstS7 (Warrior race) had major impacts in Europe and in France. By contrast, PstS2 had no impact in France, while it significantly affected other parts of the world. The objective of this study was to better understand factors t ...

... Wheat cultivar VL Gehun 892 has shown a high level of resistance against Australian Puccinia striiformis f. sp. tritici (Pst) pathotypes. In this study, it was crossed with Westonia, a susceptible wheat cultivar, and digenic segregation was observed in the derived population against Pst pathotype 134 E16A+Yr17+Yr27+. Single-gene recombinant inbred line (RIL) populations were developed from F₃ fami ...
... Yellow rust (YR), or stripe rust, is a fungal infection of wheat (Triticum aestivum L.) caused by the pathogen Puccinia striiformis Westend f. sp. tritici (Pst). Although much research has focused on YR leaf infection, we are not aware of studies investigating the genetic control of YR resistance in the wheat ear. Using an eight‐founder multiparent advanced generation intercross (MAGIC) population ...

Abstract:
... Wheat stripe rust, caused by the fungal pathogen Puccinia striiformis f. sp. tritici (Pst), occurs in all major wheat‐growing regions worldwide and poses a constant threat to production. In South Africa, Pst first emerged in 1996 in the Western Cape and has since caused frequent epidemics with three further distinct races (pathotypes) recorded to date. Herein, we undertook detailed genomic‐based a ...

For three of the four most significant QTL, haplotype analysis indicated resistance alleles were rare in European wheat. Stripe rust, or yellow rust (YR), is a major fungal disease of wheat (Triticum aestivum) caused by Puccinia striiformis Westend f. sp. tritici (Pst). Since 2011, the historically ...

BACKGROUND: YrU1 is a nucleotide-binding site (NBS) and leucine-rich repeat (LRR) protein (NLR), with additional ankyrin-repeat and WRKY domains and confers effective resistance to stripe rust fungus Puccinia striiformis f. sp. Tritici (Pst). YrU1 was positionally cloned in the progenitor species of the A genome of bread wheat, Tricicum urartu, recently. However, the molecular mechanism and compon ...
