| Outline of Final Research Achievements |
Plants in the arid lands, such as wild watermelon, accumulated a large amount of cuticle waxes upon drought stress. The wax-fortified plant leaves showed an increased ratio of reflection of incident light, suggesting that the wax fortification contributes to the avoidance of excess light absorption under high light stress. Gene expression patterns of wax biosynthetic genes were analyzed in this study, and candidated transcription factors responsible for the transcriptional regulation of these biosynthetic pathway were identified. Moreover, a novel analytical method of analyzing the chemical structure of cuticle layer by Fourier-transformed infrared spectroscopy was developed in this study.
