Influence of cell wall degrading enzymes on colonization of N2 fixing bacterium, Azorhizobium caulinodans in rice.

In rice, nodule like structures were formed by inoculation of A. caulinodans combined with growth regulators and enzymes. Among the treatments, combination of cell wall degrading enzyme mixture and NAA with A. caulinodans induced more number of paranodules in rice. Total nitrogen content also increased in treated plants compared to uninoculated control.
