McpT, a Broad-Range Carboxylate Chemoreceptor in Sinorhizobium meliloti

Abstract

alfalfa symbiosis relies on the early exchange and recognition of chemical signals. The present study contributes to the disclosure of this complex molecular dialogue by investigating the underlying mechanisms of carboxylate sensing in S. meliloti. Understanding individual steps that govern the S. meliloti-alfalfa molecular cross talk helps in the development of efficient, commercial bacterial inoculants that promote the growth of alfalfa, which is the most cultivated forage legume in the world, and improves soil fertility.
