Abstract
Two-dimensional electrophoresis of plant protein under the different light distributions had been tried to find an index of environmental impact to crops. Two kinds of tomato nursery plants, Momotaro and Sugar lamp were sampled. For one month after the germination, plants were cultivated under white and yellow lights, respectively. The 2-D PAGE protein maps were investigated. On the spot volume distributions of each molecular weight sections, the kurtosis of both kinds of tomato plants under the yellow light condition was larger than that under the white light. On the spot volume distributions of each isoelectric point sections, the skewness of both kinds of tomato plants under the yellow light condition was larger than that under the white light. This analysis method might be possible to indicate the difference of plant physiological response such as morphogenesis. Further investigation under various kinds of environmental conditions will be needed.
