* Output sequences were classified into reference (100%
identity in at least 1 of 196 Rhizobium leguminosarum symbiovartrifolii genomes ), exact BLAST (100% query coverage
and 100% identity against the whole-genome shotgun contigs BLAST
database), single nt (one nt difference from either reference
or exact BLAST match), and other .
† The population globalF ST (fixation index) is an estimate of genetic
differentiation among populations based on relative allele abundance.
