Insight Into

Soybean mosaic virus (SMV) and peanut mottle virus (PMV) are two potyviruses that cause yield losses and reduce seed quality in infested soybean (Glycine max (L.) Merr.) fields throughout the world. Rsv1 and Rpv1 are genes that provide soybean with resistance to SMV and PMV, respectively. Isolating and characterizing Rsv1 and Rpv1 are instrumental in providing insight into the molecular mechanism of potyvirus recognition in soybean. A population of 1056 F2 individuals from a cross between SMV- and PMV-resistant line PI 96983 (Rsv1 and Rpv1) and the susceptible cultivar 'Lee 68' (rsv1 and rpv1) was used in this study. Disease reaction and molecular-marker data were collected to determine the linkage relationship between Rsv1, Rpv1, and markers that target candidate disease-resistance genes. F2 lines showing a recombination between two of three Rsv1-flanking microsatellite markers were selected for fine mapping. Over 20 RFLP, RAPD, and microsatellite markers were used to map 38 loci at high-resolution to a 6.8-cM region around Rsv1 and Rpv1. This study demonstrates that Rsv1 and Rpv1 are tightly linked at a distance of 1.1 cM. In addition, resistance-gene candidate sequences were mapped to positions flanking and cosegregating with these resistance loci. Based on comparisons of genetic markers and disease reactions, it appears likely that several tightly linked genes are conditioning a resistance response to SMV. We discuss the specifics of these findings and investigate the utility of two disease resistance related probes for the screening of SMV or PMV resistance in soybean.Key words: NBS, multigene family, and disease resistance.

Linkage Relationships

Six new isozymes and three morphological markers were placed on the lentil (Lens culinaris L.) linkage map. The 17 isozymes and 11 morphological markers that were studied formed four linkage groups (I through IV). These linkage groups represent linkage relationships in the cultivated lentil (L. c. ssp. culinaris) and its wild progenitor (L. c. ssp. orientalis). However, in crosses between L. c. ssp. odemensis and other ssp. of L. culinaris, linkage relationships were slightly different. In these crosses markers of linkage groups III and IV showed disturbed segregation and pseudo-linkage. Although wide crosses contain more variability than narrow crosses in lentil, linkage relationships are more difficult to interpret because of the prevalence of disturbed segregation and pseudo-linkage. Key words: Lentil, Lens culinaris, linkage, isozyme, pseudo-linkage
