摘要：

IAA-deficient mutants T10, T27 and TN3 were isolated from B. elkanii USDA 31 by spontaneous and/or N-methyl-N'-nitro-N-nitrosoguanidine (NTG) mutageneses. Inoculation with these mutants significantly reduced the nodule number on soybean roots when compared to that of the parent strain. Furthermore, exogenous IAA application restored the nodule number of soybeans inoculated with TN3 to the original level.
