Expression of genes involved in flavonoid biosynthesis in the flowers of CsWD40-overexpressing tobacco plants. (A) A schematic diagram of flavonoid biosynthetic pathway. (B) Expression profiles of genes in flavonoid pathway in flowers of transgenic CsWD40 tobacco lines. CHS, chalcone synthase; F3H, flavanone 3-hydroxylase; F3′H, flavonoid 3-hydroxylase; DFR, dihydroflavonol reductase; ANS, anthocyanidin synthase; ANR, anthocyanidin reductase; FLS, flavonol synthase; AN2, N. tabacum Anthocyanin 2; AN1a, N. tabacum Anthocyanin 1a; AN1b, N. tabacum Anthocyanin 1b.
