Abstract

By complementation test of NA-05, NA-07 and NA-08 with plasmids carrying exo genes of R. meliloti and Rhizobium sp. NGR234, the function of the exo gene cloned in pRK415 (the pRKM578) was identified as encoding for UDP-glucose-4-epimerase, as the exoB of R. meliloti and exoC of R. sp. NGR234.
