Abstract

Alleles, or tightly linked genes, at the soybean (Glycine max L. Merr.) Rpg1 locus confer resistance to races of Pseudomonas syringae pv. glycinea that express the avirulence genes avrB or avrRpm1. In this study we demonstrate that Rpg1 maps to a cluster of previously identified resistance genes, including those effective against fungal, viral and nematode pathogens. Rpg1 is in molecular linkage group (MLG) F, flanked by the markers K644 and B212. The RFLP markers R45, php2265 and php2385 cosegregated with Rpg1, as did the marker nbs61, which encodes a protein related to previously isolated resistance genes.
