Leaf 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 کاملTransgenic wheat expressing a barley class II chitinase gene has enhanced resistance against Fusarium graminearum
Fusarium head blight (FHB; scab), primarily caused by Fusarium graminearum, is a devastating disease of wheat worldwide. FHB causes yield reductions and contamination of grains with trichothecene mycotoxins such as deoxynivalenol (DON). The genetic variation in existing wheat germplasm pools for FHB resistance is low and may not provide sufficient resistance to develop cultivars through traditi...
متن کاملInduced Acidic chitinase Expression and Scab-Resistant in Wheat Under Field Condition
Fusarium head blight (FHB) caused by Fusarium graminearum is responsible for billions of dollars in agriculture losses. The goal of the present study was evaluation the expression of acidic chitinase, one of PR proteins, in wheat defense response against different FHB induced treatments in 'Falat' as a highly susceptible and 'Sumai3' as a tolerant cultivar. These treatments contained fungi extr...
متن کاملNeopolyploidy and pathogen resistance.
Despite the well-documented historical importance of polyploidy, the mechanisms responsible for the establishment and evolutionary success of novel polyploid lineages remain unresolved. One possibility, which has not been previously evaluated theoretically, is that novel polyploid lineages are initially more resistant to pathogens than the diploid progenitor species. Here, we explore this possi...
متن کاملJacalin domain in wheat jasmonate-regulated protein Ta-JA1 confers agglutinating activity and pathogen resistance.
Ta-JA1 is a jacalin-like lectin from wheat (Triticum aestivum) plants. To date, its homologs are only observed in the Gramineae family. Our previous experiments have demonstrated that Ta-JA1 contains a modular structure consisting of an N-terminal dirigent domain and a C-terminal jacalin-related lectin domain (JRL) and this protein exhibits a mannose-specific lectin activity. The over-expressio...
