| description | Bean golden yellow mosaic virus (BGYMV) is a whitefly-transmitted geminivirus of the Begomovirus family that causes important yield losses to common beans grown in tropical and sub-tropical countries of Latin America and the Caribbean. A major resistance gene that has been widely deployed in this region is the recessive locus bgm-1 that prevents the development of severe yellowing typical of the disease. In this study, we developed a co-dominant sequence-characterized amplified region (SCAR) marker, SR2, based on a previously identified random amplified polymorphic DNA (RAPD) marker that is tightly linked to the bgm-1 resistance gene and identified the position of the locus in the common bean genome through comparative mapping using two genetic maps for the species. The SR2 marker was mapped relative to bgm-1 in a segregating population of recombinant inbred lines developed from the resistant × susceptible cross of DOR476 × SEL1309. Polymorphism was shown to be based on a 37 bp insertion event in the SR2 allele associated with susceptibility compared to the allele associated with resistance and the marker mapped at a distance of 7.8 cM from the resistance gene. The SR2 marker was significantly associated with overall disease symptoms and with three of the four symptoms associated with the disease (yellowing or chlorosis, flower abortion, foliar deformation) in a greenhouse trial in Colombia with the mechanically transmissible BGYMV–Guatemala strain. In both the DOR364 × G19833 and BAT93 × Jalo EEP558 mapping populations, SR2 was located near the end of linkage group b03 (chromosome 5) suggesting a sub-telomeric position. The position of the bgm-1 resistance gene was estimated to be close to that of bc-1, a strain-specific resistance gene for Bean common mosaic virus (BCMV), based on linkage of SR2 with the SCAR marker SBD5 in the DOR364 × G19833 mapping population. The implications of linkage between these two recessive resistance genes are discussed, as this is the first association between resistance genes against both a begomovirus and a potyvirus. |
