Abstract
Symbiotic nodulation between leguminous plants and rhizobia is a critical biological interaction. The type III secretion system (T3SS) employed by rhizobia manipulates the host’s nodulation signaling, analogous to mechanisms used by certain bacterial pathogens for effector protein delivery into host cells. This investigation explores the interactive signaling among type III effectors HH103ΩNopC, HH103ΩNopT, and HH103ΩNopL from SinoRhizobium fredii HH103. Experimental results revealed that these effectors positively regulate nodule formation. Transcriptomic analysis pinpointed GmPHT1-4 as the key gene facilitating this effector-mediated signaling. Overexpression of GmPHT1-4 enhances nodulation, indicating a dual function in nodulation and phosphorus homeostasis. This research elucidates the intricate regulatory network governing Rhizobium–soybean (Glycine max (L.) Merr) interactions and the complex interplay between type III effectors.
