Abstract

A mutant strain of complex phenotype was selected in Rhizobium meliloti after nitrosoguanidine mutagenesis. It failed to grow on mannitol, sorbitol, fructose, mannose, ribose, arabitol, or xylose, but grew on glucose, maltose, gluconate, L-arabinose, and many other carbohydrates. Assay showed the enzyme lesion to be in phosphoglucose isomerase (pgi), and revertants, which were of normal growth phenotype, contained the enzyme again. Nonpermissive substrates such as fructose and xylose prevented growth on permissive ones such as L-arabinose, and in such situations there was high accumulation of fructose 6-phosphate. The mutant strain had about 20% as much exopolysaccharide as the parent. Nitrogen fixation by whole plants was low and delayed when the mutant strain was the inoculant.
