摘要:

赤霉素能够有效诱导葡萄胚珠败育,被广泛应用于葡萄的无核化生产。赤霉素诱导葡萄胚囊和花粉发育异常,造成内部生理代谢失调,该过程还受到一些植物激素合成代谢及信号通路相关基因、种子发育时期赤霉素响应基因以及特异microRNA的动态调控。本文中从胚胎学、生理生化和分子机制层面综述了赤霉素诱导葡萄无核的形成机理,以期为进一步揭示赤霉素诱导葡萄单性结实的潜在调控机制和今后利用赤霉素进行优质无核葡萄的生产提供依据。

Abstract:

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.

Key words: grape, seedless, gibberellins, parthenocarpy, regulatory mechanism
