RNA-Seq Based Transcriptomic Analysis of Bud Sport Skin Color in Grape Berries

The most common bud sport trait in grapevines is the change color of grape berry skin, and grapes mainly developed by composition accumulation anthocyanins. Many studies have shown that MYBA a key gene regulates initiation anthocyanin synthesis peels. In current study, we used skins ‘Italia’, ‘Benitaka’, ‘Muscat Alexandria’, ‘Flame Muscat’, ‘Rosario Bianco’, Rosso’, ‘Red Rosario’ at véraison stage (10 weeks post-flowering 11 post-flowering) as research materials. relative expressions genes related to skin were evaluated utilizing RNA-Seq technology. results revealed VvMYBA1/A2 three red varieties higher than white varieties. known be associated with UFGT pathway. According results, expression could also LDOX. addition, single (gene ID: Vitvi19g01871) displayed highest all samples for six this was much green compared ones. GO molecular function annotation identified it putative metallothionein-like protein ability regulate binding copper ions zinc role maintaining internal stable state cellular level. High levels screened may play an important stage.
