Figure 1From: Transcriptional control of anthocyanin biosynthetic genes in extreme phenotypes for berry pigmentation of naturally occurring grapevinesAnthocyanin concentration and gene expression in berry skin. (A) Total anthocyanins in nine cultivars. Concentration is expressed as mg g-1 of skin of malvidin equivalents; (B) UFGT and (C) GST gene expression in four cultivars with no, low, medium and high amount of total anthocyanins at four ripening stages. At mid-véraison green berries were analysed separately from red berries on the same cluster; (D, E, F) linear regression between cumulative transcription of three genes (F3H, UFGT and GST) throughout ripening (calculated as the area below the expression curve) and final anthocyanin content.Back to article page
