Abstract
Here we report the phenotypic characteristics of a novel hypernodulation mutant, Ljrdh1 (root-determined hypernodulation 1) of Lotus japonicus. At 12 weeks after rhizobial inoculation, there were no differences between the growth of Ljrdh1 and, wild-type. However, Ljrdh1 showed 2 to 3 times higher nitrogen-fixing activity, and seed and pod yields, were approximately 50% higher than the wild-type. This is the first report of a legume hypernodulation mutant showing normal growth and a high-yielding characteristic under optimal cultivation conditions.
