Nodulation of leguminous plants by Rhizobium, Bradyrhizobium, and Azorhizobium spp. is dependent on the induction by the plant host of different bacterial nodulation (nod) loci. The transcription of these nod loci is activated in the presence of plant-produced flavonoids upon binding of the NodD protein--a LysR-type activator--to specific sequences present in the nod promoters. Originally, a 47-base-pair (bp) region called the nod box was shown to be the target sequence for binding of NodD… CONTINUE READING
