Outline of Final Research Achievements	The coloring mechanism of the grapes mediated by abscisic acid (ABA) signal transduction had been investivaged. In this study, green-skinned Italia (Vitis vinifera L.) and red skinned Ruby Okuyama (V. vinifera L), which is bud sports of Italia, and tetraploid grape cultivars, Kyoho (V. labruscana L.) and Aki Queen (V. labruscana L.) had been used to demonstrate the relationship between matulation of the grapes and ABA content and the expression of the ABA signal trans duction-related genes. There were correlations between ABA content and expression of PP2C-3,6,9 and SnRK5 in the skins of V. vinifera and V. labruscana.
