Molecular markers for leaf rust resistance genes in wheat.
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...
متن کاملA Cleaved Amplified Polymorphic Sequence (CAPS) Marker Associated with Root-Knot Nematode Resistance in Sugarbeet
cluding California (Altman and Thomason, 1971; Whitney and Duffus, 1986; Duffus and Ruppel, 1993). Resistance to root-knot nematode (Meloidogyne spp.) previously Disease of sugar beet caused by root-knot nematode was introgressed into sugar beet (Beta vulgaris L.) from wild beet [B. vulgaris ssp. maritima (L.) Arcang] and was demonstrated to be is manifested by galls that form on lateral roots ...
متن کاملMolecular mapping of a stripe rust resistance gene in spring wheat cultivar Zak.
Stripe rust (yellow rust), caused by Puccinia striiformis f. sp. tritici, is one of the most devastating foliar diseases of wheat (Triticum aestivum) worldwide. Growing resistant cultivars is the best approach for control of the disease. Although the stripe rust resistance in spring wheat cv. Zak has been circumvented by a group of races of the pathogen predominant in the United States since 20...
متن کاملLinkage Maps of Wheat Stripe Rust Resistance Genes Yr5 and Yr15 for Use in Marker-Assisted Selection
Stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici Eriks.) is a serious disease of wheat (Triticum aestivum L.). Resistance genes Yr5 and Yr15 are the only known all-stage resistance genes that defeat all stripe rust races currently found in the United States. Previously mapped markers for these genes, however, show limited polymorphism across diverse genotypes and/or map at a ...
متن کاملMolecular Markers for Leaf Rust Resistance Gene Lr42 in Wheat
Wheat leaf rust, caused by Puccinia triticina Eriks., is an important wheat (Triticum aestivum L.) foliar disease worldwide. Growing cultivars incorporating genetic resistance is one of the most effective approaches for disease control. Leaf rust resistance gene Lr42 was identified from a wheat relative, Aegilops tauschii Coss. (goatgrass), and has been transferred into hard winter wheat. A pre...
