Mutants of LjPUB13 have reduced nodulation. a Number of nodules per plant and b number of nodules per root cm in pub13.1 and pub13.2 mutants compared to wild type plants at 14 and 21 dpi, c frequency of plants carrying nodules, d number of infection threads per root cm in pub13.1 and pub13.2 mutants compared to wild type plants at 10 and 14 dpi. Graphs show means (+SE) of at least three biological replications (n = 10). Significant differences (P < 0.05) are indicated by asterisk. Comparisons are between wild-type and pub13 mutants
