Anthocyanin is not only ROS scavengers but also pigments for organ color.Their biosynthesis is inhibited by nitrate.In the apple, MdMYB1 is a master regulator for anthocyanin biosynthesis and fruit coloration.In this study, we found that the MdMYB 1 protein was degraded via an ubiquitin-dependent pathway in response to nitrate.Subsequently, MdMYB 1 was used as a bait protein to screen for its interacting proteins in a yeast two-hybrid approach.
