Succinoglycan is required for initiation and elongation of infection threads during nodulation of alfalfa by Rhizobium meliloti.

Journal of bacteriology - 1 Oct 1998

Cheng H P, Walker G C

Abstract excerpt

Rhizobium meliloti Rm1021 must be able to synthesize succinoglycan in order to invade successfully the nodules which it elicits on alfalfa and to establish an effective nitrogen-fixing symbiosis. Using R. meliloti cells that express green fluorescent protein (GFP), we have examined the nature of the symbiotic deficiency of exo mutants that are defective or altered in succinoglycan production. Our observations...
