T. Ashfield et al., RPG1, A SOYBEAN GENE EFFECTIVE AGAINST RACES OF BACTERIAL-BLIGHT, MAPS TO A CLUSTER OF PREVIOUSLY IDENTIFIED DISEASE RESISTANCE GENES, Theoretical and Applied Genetics, 96(8), 1998, pp. 1013-1021
Alleles, or tightly linked genes, at the soybean (Glycine max L. Merr.
) Rpg1 locus confer resistance to races of Pseudomonas syringae pv, gl
ycinea that express the avirulence genes avrB or avrRpm1. In this stud
y we demonstrate that Rp,ol 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, flank
ed by the markers K644 and B212, The RFLP markers R45, php2265 and php
2385 cosegregated with Rp,ol, as did the marker nbs61, which encodes a
protein related to previously isolated resistance genes.
