【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。更多还原

【Abstract】 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.更多还原
