摘　　要：综述了CO/FT调节元件与植物开花时间调节的最新研究进展。开花是植物由营养生长向生殖生长转变的关键过程。光周期和温度在植物开花时间控制中起主要作用。在拟南芥和水稻中,CONSTANS(CO)对植物的日照长度测定至关重要,它与其靶基因FLOWERINGLOCUST(FT)构成的调节元件(regulon)在依赖于光周期的开花过程中起重要作用。目前已从多种植物中鉴定出CO和FT基因,并对其在开花时间的调控作用进行了深入研究。In this review, we focus on the recent progress made in CO/FT regulon and its role in adjusting plant flowering. Flowering is a key process for plant to transfer from vegetative to reproductive development. Photoperiod and temperature play critical roles in controlling flowering time. In Arabidopsis and rice, CONSTANS （ CO ） and its target gene FLOWERING LOCUS T（FT） play a key role in day-length measurement. The CO/FT regulon has played an important role in photoperiod-dependent flowering. At present, CO and FT orthologs have been identified from different plant species,and their roles in plant flowering time control have been studied intensively.
