Notes	By infiltration with both wild type strains and virulent N-methyl-N'-nitro-N-nitrosoguanidine (NTG)-induced mutants of Xaszthomonas cantpestfis pv. oryzae cowpea leaf tissues produced necrosis within 24 hr, which could be designated as typical hypersensitive reaction (HR). Among fractions of bacterial culture tested, only living bacterial celIs were effective for necrosis inductivity, while heat-killed cells, culture filtrate and extracellular polysaccharide were ineffective. HR was induced at a concentration level higher than ca. lo7 cells/ml of virulent bacteria, while neither necrosis nor yellowish discoloration developed with the bacteria below 104 cells/ml. Avirulent mutant strains did not induce necrosis in cowpea leaf even at a concentration higher than 101 cells/ml, while the virulent revertant regained the necrosis inductivity associating with the restoration of virulence.
