Analysis of Mesorhizobium loti glycogen operon: effect of phosphoglucomutase (pgm) and glycogen synthase (g/gA) null mutants on nodulation of Lotus tenuis.

Molecular plant-microbe interactions : MPMI - 1 Apr 2002

Abstract excerpt

The phosphoglucomutase (pgm) gene codes for a key enzyme required for the formation of UDP-glucose and ADP-glucose, the sugar donors for the biosynthesis of glucose containing polysaccharides. A Mesorhizobium loti pgm null mutant obtained in this study contains an altered form of lipopolysaccharide (LPS), lacks exopolysaccharide (EPS), beta cyclic glucan, and glycogen and is unable to nodulate Lotus tenuis. The...
