Research Progresses on Photoperiodic Flowering and Yield Traits in Soybean(Glycine max Merr.)

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.
