Abstract

14-3-3 proteins are regulatory proteins that play a major role in a lot of important processes in plants, but their role in the regulation of the secondary metabolism is still poorly documented. For the first time, we demonstrated that the activity of ANS, an important enzyme of the flavonoid pathway, can be modulated in vitro by 14-3-3 proteins in grapevine.
