In soybean (Glycine max. (L) Merr.), hypernodulation mutant lines produced small-size leaves due to the smaller number of leaf cells, compared to wild type. So the autoregulation of nodulation is related to the control system of leaf cell proliferation in soybean. In this study, leaf growth of hypernodulation mutant har1-4 in Lotus japonicus was compared with wild type. Leaf area of hypernodulation mutant har1-4 is similar with the wild type. Cell number of leaf of har1-4 tended to be lower than that of wild type, while cell area of har1-4 tended to be larger than that of wild type. These results indicate that a part of the autoregulation of nodulation might be related to cell proliferation in leaves also in L. japonicus as shown in soybean. The system of autoregulation of nodulation in legume should be a part of general plant mechanisms rather than specific to nodulation.
