Schematic representation of the symbiosis region. Genes described in the text are indicated by arrows; the others are not individually represented, but their number is specified in the pentagons. The symbiotic region is flanked by tRNA-Gly (triangles) and interspersed by multiple transposases and integrases (blue lines). Genes in the nod A operon are nod ABCSUIJZnoe CHOP and genes in the trb operon are trb BCDEJLFGI.
