Advance in The Flowering Time Control of Arabidopsis / 生物化学与生物物理进展

Flowering is one of the most important progresses for most plants during the transition from vegetative growth to reproductive growth. There are many factors that affect the flowering, including two main external factors, light and temperature, and the internal factors such as gibberellin acid (GA) and autonomous elements. At present, the late-flowering mutants are fallen into four pathways: photoperiod pathway, vernalization pathway, autonomous pathway and GA pathway according to factors described above. Through several floral integrators, such as SOC1, FT and LFY, the multiple flowering regulatory pathways control the flowering finely under the variable environmental condition and physiological condition.
