Wheat leaf rust caused by Puccinia triticina.
UNLABELLED Leaf rust, caused by Puccinia triticina, is the most common rust disease of wheat. The fungus is an obligate parasite capable of producing infectious urediniospores as long as infected leaf tissue remains alive. Urediniospores can be wind-disseminated and infect host plants hundreds of kilometres from their source plant, which can result in wheat leaf rust epidemics on a continental ...
متن کاملGeneration of a wheat leaf rust, Puccinia triticina, EST database from stage-specific cDNA libraries.
SUMMARY Thirteen cDNA libraries constructed from small amounts of leaf rust mRNA using optimized methods served as the source for the generation of 25 558 high-quality DNA sequence reads. Five life-cycle stages were sampled: resting urediniospores, urediniospores germinated over water or plant extract, compatible, interactive stages during appressorium or haustorium formation just before sporul...
متن کاملVirulence and Molecular Polymorphism in International Collections of the Wheat Leaf Rust Fungus Puccinia triticina.
ABSTRACT Collections of Puccinia triticina, the wheat leaf rust fungus, were obtained from Great Britain, Slovakia, Israel, Germany, Australia, Italy, Spain, Hungary, South Africa, Uruguay, New Zealand, Brazil, Pakistan, Nepal, and eastern and western Canada. All single-uredinial isolates derived from the collections were tested for virulence polymorphism on 22 Thatcher wheat lines that are nea...
متن کاملDraft Genome Sequence of the Fungus Lecanicillium psalliotae Strain HWLR35, Isolated from a Wheat Leaf Infected with Leaf Rust (Caused by Puccinia triticina)
Lecanicillium psalliotae is an entomopathogenic, mycoparasitical, and nematophagous fungus known to produce antibiotic and antifungal compounds. Here, we report the first 36-Mb draft genome sequence of L. psalliotae strain HWLR35. The draft genome contains 197 scaffolds and is predicted to have 11,009 protein-coding genes.
متن کاملVirulence and molecular polymorphisms of the wheat leaf rust fungus Puccinia triticina in Canada
Populations of Puccinia triticina, one of the casual agents of wheat leaf rust disease, in the pacific (British Columbia and Alberta), prairie (Manitoba and Saskatchewan), and eastern regions (Quebec and Ontario) of Canada from 1997 to 2007 were analyzed for virulence and genetic diversity by revealing expressed sequence tag derived simple sequence repeat (EST-SSR) polymorphisms. Since 1997, a ...
