Abstract Crop losses caused by plant pathogens are a primary threat to stable food production. Stripe rust ( Puccinia striiformis ) is fungal pathogen of cereal crops that causes significant, persistent yield loss. exhibits host species specificity, with lineages have adapted infect wheat and barley. While stripe barley commonly restricted their corresponding hosts, the genes underlying this specificity remain unknown. Here, we show three resistance genes, Rps6 , Rps7 Rps8 contribute...
We uncouple host and nonhost resistance in barley to Puccinia striiformis ff. spp. hordei tritici . isolate, fine map, physically anchor Rps6 chromosome 7H barley. A plant may be considered a of pathogen if all known genotypes species are resistant isolates species. However, small number susceptible some this an intermediate host. Barley (Hordeum vulgare) is for f. sp. (Pst), the causal agent wheat stripe rust. wanted understand genetic architecture underlying Pst determine whether any...
In the evolution of land plants, plant immune system has experienced expansion in receptor and signaling pathways. Lineage-specific expansions have been observed diverse gene families that are potentially involved immunity but lack causal association. Here, we show Rps8-mediated resistance barley to pathogen Puccinia striiformis f. sp. tritici (wheat stripe rust) is conferred by a genetic module: Pur1 Exo70FX12, which together necessary sufficient. encodes leucine-rich repeat kinase ortholog...
Nonhost resistance is often conceptualized as a qualitative separation from host resistance. Classification into these two states generally facile, they fail to fully describe the range of that exist in transition nonhost. This poses problem when studying pathosystems cannot be classified either or nonhost due their intermediate status relative extremes. In this study, we investigate efficacy Poaceae-stripe rust (Puccinia striiformis Westend.) interaction for describing host-nonhost...
Multilayered defense responses ensure that plants are hosts to only a few adapted pathogens in the environment. The host range of plant pathogen depends on its ability fully overcome barriers, with failure at any single step sufficient prevent life cycle completion pathogen. Puccinia striiformis, causal agent stripe rust (=yellow rust), is an agronomically important obligate biotrophic fungal wheat and barley. It generally unable complete non-adapted wild grass species Brachypodium...
ABSTRACT Puccinia striiformis f. sp. hordei , the causal agent of barley stripe rust, is a destructive fungal pathogen that significantly affects cultivation. A major constraint in breeding resistant cultivars lack mapping information resistance ( R ) genes and their introgression into adapted germplasm. considerable number have been described to P. but only few loci mapped. Previously, Chen Line (1999) reported two recessive seedling Ethiopian landrace HOR 1428. In this study, we map confer...
Abstract In the evolution of land plants, plant immune system has experienced expansion in receptor and signaling pathways. Lineage-specific expansions have been observed diverse gene families that are potentially involved immunity, but lack causal association. Here, we show Rps8 -mediated resistance barley to fungal pathogen Puccinia striiformis f. sp. tritici (wheat stripe rust) is conferred by a genetic module: LRR-RK Exo70FX12 , which together necessary sufficient.
