研究了花青素生物合成途径中的7个基因在设拉子葡萄不同组织中的表达。所有组织均含有原花青素，但只有浆果果皮积累了花青素。在大多数组织中，除UDP葡萄糖-黄酮类3-o-葡萄糖基转移酶(UFGT)外，所有类黄酮类基因均有表达，但UFGT仅在浆果果皮中表达。在其他红葡萄的果皮中也观察到了类似的表达模式。在白葡萄中未检测到UFGT的表达。白葡萄品种似乎缺乏花青素，因为它们缺乏UFGT，尽管它们也降低了其他黄酮类途径基因的表达。
The expression of seven genes from the anthocyanin biosynthesis pathway was determined in different tissues of Shiraz grapevines. All of the tissues contained proanthocyanidins, but only the berry skin accumulated anthocyanins. In most tissues, all of the flavonoid genes except UDP glucose-flavonoid 3-o-glucosyl transferase (UFGT) were expressed, but UFGT expression was only detected in berry skin. Similar patterns of expression were observed in the skin of other red grapes. In white grapes, UFGT expression was not detected. White grape cultivars appear to lack anthocyanins because they lack UFGT, although they also had decreased expression of other flavonoid pathway genes.
