Competitiveness for Nodule Colonization in Sinorhizobium meliloti: Combined In Vitro -Tagged Strain Competition and Genome-Wide Association Analysis

Abstract

Decoding the competitive pattern that occurs in the rhizosphere is challenging in the study of bacterial social interaction strategies. To date, the single-gene approach has mainly been used to uncover the bases of nodulation, but there is still a knowledge gap regarding the main features that a priori characterize rhizobial strains able to outcompete indigenous rhizobia.
