Analysis of Rhizobium meliloti Sym Mutants Obtained by Heat Treatment.

N Toro1, J Olivares.   

Abstract

Deletions in the pSym megaplasmid of Rhizobium meliloti were produced at a high frequency, and their lengths varied according to incubation temperature. Morphological differentiation into large and small colonies occurred after heat treatment. Small colonies elicited pseudonodules on alfalfa roots.
