Research Progress on the Mechanism of GAs-Induced Seedlessness in Grape
Gibberellins(GAs)can effectively induce ovule abortion and are widely utilized in the production of seedless grape.Gibberellins induces abnormal development of grape embryo sac and pollen,resulting in internal physiological metabolism disorders.This process is also dynamically regulated by some genes related to plant hormone anabolism and signaling pathways,gibberellins response genes and specific microRNA during seed development.This review summarizes the mechanism of GAs-induced seedlessness in grape from the aspects of embryology,physiology,biochemistry and molecular mechanisms,with the aim of further understanding the potential regulatory mechanism of GAs-induced parthenocarpy of grape and providing a basis for using GAs in the future production of high-quality seedless grape.
