the use of silicon on systemic resistance induction against fusarium head blight disease of wheat
in this study the effect of different concentrations of silicon( 0, 2 , 4 and 6 mm, on expression of some genes involved in resistance and activity of several antioxidan enzymes was investigated: the plants was treated in flowering stage via soil solution. the treated plants were inoculated with 106 spore suspended in 1 ml by injection into the lower part of the spikelets and then were harveste...
متن کاملMolecular Mapping of Wheat Leaf Rust Resistance Gene Lr42
Leaf rust, caused by Puccinia triticina Eriks., is an important foliar disease of wheat (Triticum aestivum L.) worldwide. Leaf rust resistance gene Lr42 from Aegilops tauschii Coss. has been used as a source of rust resistance in breeding programs. To identify molecular markers closely linked to Lr42, a segregating population of nearisogenic lines contrasting for the presence of Lr42 was develo...
متن کاملLeaf Rust of Wheat: Pathogen Biology, Variation and Host Resistance
Rusts are important pathogens of angiosperms and gymnosperms including cereal crops and forest trees. With respect to cereals, rust fungi are among the most important pathogens. Cereal rusts are heteroecious and macrocyclic requiring two taxonomically unrelated hosts to complete a five spore stage life cycle. Cereal rust fungi are highly variable for virulence and molecular polymorphism. Leaf r...
متن کاملsystemic resistance induction against cucumber marginal leaf blight disease by sodium silicate application
induction of systemic resistance to cucumber against marginal leaf blight disease caused by pseudomonas marginalis using silicon application (as 1 &2 mm of sodium silicate) was studied under greenhouse conditions. results indicated that application of 2 mm of sodium silicate remarkably increased resistance in cucumber against the pathogen. according to the results, disease severity in plants tr...
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...
