Description
The effect of light intensity on Sekiguchi lesion formation and tryptamine accumulation involved in light-induced resistance of rice(cv. Sekiguchi-asahi)inoculated with Magnaporthe grisea was determined by using neutral density filters(ND). When the M. griseainoculated leaves were irradiated by ND-filtered lights from daylight fluorescent lamps, there was no difference in number of Sekiguchi lesions among attenuation rates0,20,50,75and90%. However Sekiguchi lesion development and tryptamine accumulation were enhanced with increasing the light intensity. In the dark condition(attenuation rate100%), however, no Sekiguchi lesion formation and low level accumulation of tryptamine were observed. This result suggested that Sekiguchi lesion development and tryptamine accumulation were photosynthesis activityand light intensity-dependently induced in Sekiguchi lesion mutant infected with M. grisea.
