Gene expression levels of VvHMGRs in various tissues and enzyme activities in the fruit during development stages in 'Kyoho' grape. A VvHMGRs genes expression in different grape tissues. B HMGR activities during fruit development. Berry Flesh-V indicates berry flesh in véraison period; Berry Flesh-MR indicates berry flesh in mid-ripening period; Berry Flesh-R indicates berry flesh in ripening period. Vertical bars represented standard deviations (SD) of means (n = 3). Different letters indicated a statistical difference at P < 0.05 as determined by Duncan’s multiple range test
