Abstract

Analysis of the genome sequence of bradyrhizobia strains isolated from root nodules of Lupinus mariae-josephae revealed the presence of a type III secretion system (T3SS). Mutagenesis of ttsI gene that codes for the transcriptional activator (TtsI) resulted in the formation of white, non-fixing nodules in L. mariae-josephae. The T3SS cluster includes a gene coding for a NopE-like protein with an autocleavage motif. The NopE protein is an effector in the Bradyrhizobium-soybean symbiosis (Wenzel et al., 2010). The autocatalytic properties of the purified NopE-like protein have been studied.
