Abstract excerpt

Homology was previously detected between the DNA restriction fragments containing Rhizobium meliloti nodulation genes and the 90-MDa plasmid, p90, of Azospirillum brasilense Sp7. Two DNA loci from Sp7 genome that complement mutations in the exopolysaccharide synthesis genes, exoB and exoC, of R....
