We have isolated a novel enhanced-nodulating mutant astray (Ljsym77) from Lotus japonicus. The name astray derives from the non-symbiotic phenotype of this mutant, agravitropic lateral roots that go "astray" against gravity. In this report we evaluated the symbiotic aspects of this mutant in detail. The astray mutant developed approximately twice the number of nodules on a wider area of roots compared with the wild type. Furthermore, the astray mutant demonstrated early initiation of nodule development, which is an unprecedented symbiotic phenotype. The astray seedlings showed normal sensitivity to the general inhibitors of nodulation such as ethylene and nitrate. These results indicate that the astray mutant is distinct from the hypernodulating mutants reported previously, and that the ASTRAY gene acts as an early and negative regulator in the cascade of nodule development.
