Double inoculation (15 h apart) of the soybean cultivar Williams with Bradyrhizobium japonicum I-110ARS reveals a rapid regulatory plant response that inhibits nodulation of distal portions of the primary root (M Pierce, WD Bauer 1984 Plant Physiol 73: 286-290). Only living, homologous rhizobia elicit the response. We conducted similar double inoculation experiments to test the hypothesis that this is a universal phenomenon in soybean symbioses. We investigated interactions of the cultivar… CONTINUE READING
