Abstract

Agrobacterium tumefaciens and Rhizobium meliloti carry related genetic loci which have important roles in virulence and symbiosis. Previously, it was shown that two virulence loci of A. tumefaciens, chvA and chvB, are related to two R. meliloti symbiosis loci, ndvA and ndvB, respectively (T. Dylan, L. Ielpi, S. Stanfield, L. Kashyap, C. Douglas, M. Yanofsky, E. Nester, D. R. Helinski, and G. Ditta, Proc. Natl. Acad. Sci. USA 83:4403-4407, 1986). Here we show that these two phytobacteria possess additional related virulence/symbiosis genes. Results of genetic complementation and DNA hybridization experiments indicate that the pscA virulence locus of A. tumefaciens is structurally and functionally related to the exoC symbiosis locus of R. meliloti. Thus, A. tumefaciens and R. meliloti bear at least three related genetic loci that have crucial roles in establishing the interactions that each bacterium has with its respective host plants.
