摘要
大豆作为重要的经济作物,是人类植物油和植物蛋白的主要来源,但目前我国大豆产业面临严峻的挑战。大豆光周期开花不仅影响大豆的种植适应性,而且决定着大豆的产量。文章阐述了大豆特有的光周期开花调控途径Phy A-E1-FT,同时论述了光周期开花调控基因间的相互作用关系。大豆光周期反应中重要基因的克隆为理解开花期和生育期分子机理提供理论基础,同时对大豆分子育种和提高大豆产量具有重要意义。
Soybean as an important industrial crop, which is a predominant plant source for human vegetable oil and protein.But now our country′s soybean industry faces severe challenges.Soybean photoperiod regulated flowering not only influences soybean adaptation but also affects soybean grain yield.In this review, we demonstrated that soybean contains a specific photoperiod regulated flowering pathway PhyA-E1-FT.We also elucidated the genetically regulation relationship between identified flowering genes in soybean.The clone of key genes in soybean photoperiod response will serve as a theoretical basis for flowering and maturity molecular mechanism, and will be of great importance in soybean molecular breeding and yield improvement.
