Metabolism of Tryptophan and Tryptophan Analogs by Rhizobium meliloti.

M N Williams1, E R Signer.   

Abstract

The alfalfa symbiont Rhizobium meliloti Rm1021 produces indole-3-acetic acid in a regulated manner when supplied with exogenous tryptophan. Mutants with altered response to tryptophan analogs still produce indole-3-acetic acid, but are Fix(-) because bacteria do not fully differentiate into the nitrogen-fixing bacteriod form. These mutations are in apparently essential genes tightly linked to a dominant streptomycin resistance locus.
