Diversity of Sinorhizobium meliloti from the Central Asian Alfalfa Gene Center

Abstract
Sinorhizobium meliloti was isolated from nodules and soil from western Tajikistan, a center of diversity of the host plants ( Medicago , Melilotus , and Trigonella species). There was evidence of recombination, but significant disequilibrium, between and within the chromosome and megaplasmids. The most frequent alleles matched those in the published genome sequence.
