VvERF045 Integrates Ethylene, Brassinosteroid and Abscisic Acid Pathways to Orchestrate Anthocyanin Biosynthesis in Grapevine

Plant Biotechnology Journal, EarlyView.
ABSTRACT Anthocyanin biosynthesis in non‐climacteric grape berries is regulated through coordinated phytohormonal signalling networks. However, the precise mechanisms by which abscisic acid (ABA), brassinosteroids (BRs) and ethylene (ET) synergistically modulate this process remain unclear.
