Conteúdo: | Asian Soybean Rust (ASR) is a formidable threat to soybean production in many areas of the world and has recently made its way to the United States. Thus far, only four sources of resistance have been identified (Rpp1, Rpp2, Rpp3 and Rpp4). Previous work by Silva et al. (2007) mapped the Rpp4 gene to linkage group G of soybean. SSR marker Satt288, located within 2 cM of the Rpp4 gene, was used to screen the Iowa State University/USDA-ARS "Williams 82" BAC library (GM_Wba). Primers designed from BAC-end sequences and SSR Sat_143 were used to anchor and further expand the contig. Skim sequencing of selected BACs within the contig revealed a cluster of disease resistance genes that have not been previously identified in soybean. SSR markers are being developed within the gene cluster to pinpoint the region of resistance genes and to aid in breeding efforts if this gene cluster proves to be responsible for ASR resistance.
