FIG 3.

Genetic determinants associated with single and mixed nodule occupancy. (A) k-mers mapping in a region containing a vir operon on the genomes of Sinorhizobium meliloti GR4, KH35c, AK58, RU11/001, and SM11. Genes containing one or more k-mers are indicated with a black arrow; gene annotation is referred to the Prokka output. (B and C) Frequency of candidate functions of gene hits (B) and regulatory regions (C) identified by 51 top k-mers in the most competitive strains. The frequency of candidate functions reported as COG annotations (rows) in each strain (columns) is represented by grayscale shades.
