Translocation of NopP by <i>Sinorhizobium fredii</i> USDA257 into <i>Vigna unguiculata</i> Root Nodules

Abstract

Sinorhizobium fredii is a nitrogen-fixing legume symbiont that stimulates the formation of root nodules. S. fredii nodulation of roots is influenced by Nop proteins, which are secreted through a type III secretion system (T3SS). We demonstrate that S. fredii injects NopP into Vigna unguiculata nodules in a T3SS-dependent manner.
