Abstract
One modulation phenotype accounts for half of the isolated mutants of Rhizobium phaseoli CFN42 defective in symbiosis with bean. The phenotype is to elicit small, white nodules that are obviously not completely developed and lack nitrogen-fixing activity (Noel et al, 1984). One mutant class with this phenotype (Ndv-) has been described previously (VandenBosch et al, 1985). These mutants induce early stages of nodule development without infection thread formation; in minimal agar culture they are not stained by Calcofluor, a β-1,4-glycan stain. Another major class is described below. Mutants of this second class elicit an abortive infection thread with abnormal morphology; they are defective in lipopolysaccharide (LPS).
