Association Analysis Identifies Melampsora ×columbiana Poplar Leaf Rust Resistance SNPs
Populus species are currently being domesticated through intensive time- and resource-dependent programs for utilization in phytoremediation, wood and paper products, and conversion to biofuels. Poplar leaf rust disease can greatly reduce wood volume. Genetic resistance is effective in reducing economic losses but major resistance loci have been race-specific and can be readily defeated by the ...
متن کاملPatterns of genomic variation in the poplar rust fungus Melampsora larici-populina identify pathogenesis-related factors
Melampsora larici-populina is a fungal pathogen responsible for foliar rust disease on poplar trees, which causes damage to forest plantations worldwide, particularly in Northern Europe. The reference genome of the isolate 98AG31 was previously sequenced using a whole genome shotgun strategy, revealing a large genome of 101 megabases containing 16,399 predicted genes, which included secreted pr...
متن کاملAbundant Pathogenic Variation in the New Hybrid Rust Melampsora xcolumbiana on Hybrid Poplar.
ABSTRACT The recently described rust hybrid Melampsora xcolumbiana was discovered as a result of its novel pathogenic variation on Populus trichocarpa x P. deltoides (TxD) hybrid poplar. To characterize this pathogenic variation, 10 commercial TxD clones, all F(1) clones, were chosen as host differentials. Fourteen mononuredinial isolates of Pacific Northwestern field collections of M. xcolumbi...
متن کاملGeographic Variation in Melampsora Rust Resistance in Eastern Cottonwood in the Lower Mississippi Valley
-Eastern cottonwood clones originating from 36 young natural stands along the Mississippi River from Memphis, Tennessee, to Baton Rouge, Louisiana, were evaluated in a nursery near Greenville, Mississippi for resi~tance to Melampsora rust. In general, the northern sources had more rust and were more variable in rust susceptibility than the southern sources. Eleven percent of the clones from the...
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...
