Fine mapping of Ur - 3 , a historically important rust resistance locus in 1 common bean
63 Bean rust is a devastating disease of common bean in the Americas and Africa. The historically 64 important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen 65 that overcome all known rust resistance genes. Existing molecular markers tagging Ur-3 for use 66 in marker assisted selection produce false results. We described here the fine mapping of Ur-3 67 fo...
متن کاملFine Mapping of Ur-3, a Historically Important Rust Resistance Locus in Common Bean
Bean rust, caused by Uromyces appendiculatus, is a devastating disease of common bean (Phaseolus vulgaris) in the Americas and Africa. The historically important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen that overcome other rust resistance genes. Existing molecular markers tagging Ur-3 for use in marker-assisted selection produce false results. Here, w...
متن کاملMarker-Assisted Molecular Profiling, Deletion Mutant Analysis, and RNA-Seq Reveal a Disease Resistance Cluster Associated with Uromyces appendiculatus Infection in Common Bean Phaseolus vulgaris L.
Common bean (Phaseolus vulgaris L.) is an important legume, useful for its high protein and dietary fiber. The fungal pathogen Uromyces appendiculatus (Pers.) Unger can cause major loss in susceptible varieties of the common bean. The Ur-3 locus provides race specific resistance to virulent strains or races of the bean rust pathogen along with Crg, (Complements resistance gene), which is requir...
متن کاملIdentification and characterization of a NBS–LRR class resistance gene analog in Pistacia atlantica subsp. Kurdica
P. atlantica subsp. Kurdica, with the local name of Baneh, is a wild medicinal plant which grows in Kurdistan, Iran. The identification of resistance gene analogs holds great promise for the development of resistant cultivars. A PCR approach with degenerate primers designed according to conserved NBS-LRR (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (R) gene...
متن کاملDiversity of Resistance Gene Analogues in Rust Resistance and Susceptible Bread Wheat Varieties
Fungal diseases, especially leaf and stripe rusts are wheat yield reducing factors in Iran and the world. In this study, genetic diversity of 20 wheat varieties with different response to leaf and stripe rusts were studied using primers designed based on the conserved regions of plant disease resistance genes. The banding patterns of polymorphic markers were scored as dominant and number of amp...
