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 ...

15 صفحه اولGenetic Variation and Virulence on Lr26 in Puccinia triticina.
ABSTRACT The genetic relationships between isolates of Puccinia triticina virulent on wheat with the Lr26 resistance gene were studied. The diversity within and between isolates of P. triticina from Israel, Europe, and the United States was determined by virulence on near-isogenic Thatcher lines and by random amplified polymorphic DNA. According to the molecular markers, isolates that were viru...
متن کاملMolecular Diversity in Puccinia triticina Isolates from Ethiopia and Germany
A total of 43 isolates of the wheat leaf rust fungus, Puccinia triticina Eriks, collected from Ethiopia and Germany were analysed for their genetic diversity using the amplified fragment length polymorphism (AFLP) technique. Out of 18 EcoRI/MseI primer combinations screened, 15 produced 219 highly polymorphic fragments. The average AFLP difference between pairs of the leaf rust isolates (26 fro...
متن کاملMAPEAMENTO DE GENES DE RESISTÊNCIA QUANTITATIVA A Puccinia polysora EM MILHO*
Mapping of resistance genes to Puccinia polysora in maize The objectives of this study were to identify microsatellite markers linked to resistance gene of resistance to Puccinia polysora and to estimate the phenotypic effect of these genes on two monocyclic variables lesion, number and length. Two inbreed lines with different degrees of resistance (Z-95 and Z-93), the hybrid (Z-95 X Z-93) and ...
