Abstract

Root nodule formation is regulated by several plant hormones, but the details of the regulation of the nodulation signaling pathway are largely unknown. In this study, the role of gibberellin (GA) in the control of root nodule symbiosis was investigated at the physiological and genetic levels in Lotus japonicus. Exogenous application of biologically active GA, GA(3), inhibited the formation of infection threads and nodules, which was counteracted by the application of a biosynthesis inhibitor of GA, Uniconazole P. Nod factor-induced root hair deformation was severely blocked in the presence of GA, which was phenocopied by nsp2 mutants. The number of spontaneous nodules triggered by the gain-of-function mutation of calcium/calmodulin-dependent kinase (CCaMK) or the lotus histidine kinase 1 (LHK1) was decreased upon the addition of GA; moreover, the overexpression of the gain-of-function mutation of L. japonicus, SLEEPY1, a positive regulator of GA signaling, resulted in a reduced nodule number, without other aspects of root development being affected. These results indicate that higher GA signaling levels specifically inhibit the nodulation signaling pathway. Nod factor-dependent induction of NSP2 and NIN was inhibited by exogen...Continue Reading
