Abstract excerpt

The pea mutant line P55 is defective in root nodule formation, and this phenotype is controlled by a single recessive gene. Complementation analysis revealed that the mutation in P55 is allelic to sym19, which has previously been mapped to linkage group I. Detailed mapping revealed that the sym19 and ENOD40 loci are separated by 2.7 cM. We identified four recombination events, demonstrating that the nodulation...
