Gene relative expression levels of the anthocyanin biosynthesis pathway in grape berries during the five developmental stages in Urumqi and Turpan. The data presented are as mean ± SD of triplicates. PAL encodes phenylalanine ammonia lyase; 4CL encodes 4-coumarate-CoA ligase; CHS2 encodes chalcone synthase; CHI encodes chalcone isomerase; F3H encodes flavanone 3-hydroxylase; F3′H encodes flavonoid-3′-hydroxylase; F3′5′H encodes flavonoid-3′5′-hydroxylase; DFR encodes dihydroflavonol-4-reductas; ANS encodes anthocyanin synthase; and ANR encodes anthocyanidin reductase. RG stand for ‘Red Globe’ grapes; XY stand for ‘Xin Yu’ grapes; U stands for Urumqi; T stands for Turpan. Bars with different letters differ significantly at p < 0.05.
