摘要
Higher plants go through numerous developmental transitions during their life cycle. Among these transitions, the floral transi- tion is the best studied. Analyses of the regulation of flowering in Arabidopsis have provided a thorough understanding of how environmental signals and endogenous cues are integrated to create the developmental switch in plants （Michaels. 2009）.
