摘要: Seasonal flowering of plants involves responses to many environmental signals including changes in irradiance, temperature and daylength. The range complexity inputs is summarized by Thomas Vince-Prue (1997) but integrating this information into plant response has only begun recently. Genetic studies time Arabidopsis (Simpson Dean, 2002) highlight a network interacting pathways involving daylength, vernalization, photosynthetic input gibberellin (GA) fifth, autonomous pathway, whereby the progresses absence external signals.
