摘要： This research investigated the evolution of both monoterpenoids and expression profiles of related biosynthesis genes in the MEP pathway in seven different table grape varieties from veraison to maturity stage in two seasons, and the correlation was further evaluated between monoterpenoid accumulation and expression of these genes studied in these varieties. Results showed that linalool, trans-furan linalool oxide, geraniol, and cis-furan linalool oxide were the main compounds in the five Muscat varieties two seasons. 'Zaomeiguixiang' had the highest contents of geraniol and beta-Citronellol. 'Xiangfei' had the most abundant of linalool and cis-furan linalool oxide, whereas the neutral varieties of 'Moldova' and 'Christmas Rose' had the least amount. Monoterpenoid volatiles have been grouped in three evolutionary patterns in the berry development of these varieties. 'Zaomeiguixiang' and 'Xiangfei' had distinct different pattern of terpenoids evolution profiles. Pearson's correlation analysis showed that in the MEP pathway, the first biosynthesis gene VvDXS3 was significantly correlated to the accumulation of monoterpenoids, and appeared to be an important candidate gene for synthesis of the monoterpenoids.
