Abstract

SUMMARY: Ineffective mutants of were isolated at a frequency of about 3% following mutagenesis of an effective parental strain. Two mutants were temperature sensitive; they were ineffective at 26° but were effective at 13°. The morphologies of the nodules formed by these two mutants at 26° were different from each other and from normal nodules. Temperature-shift experiments using nodulated plants also indicated that the mutants had different properties.
