摘 要: Flowering Locus T (FT)基因是高等植物开花信号调控中一个重要的整合因子,它通过调控花原基特异性基因的表达来启动花原基的分化。研究MADS-box基因Cauliflower (CAL)对开花时间的影响以及FT对CAL基因表达的调控。研究结果表明超表达CAL基因诱导的开花过程依赖于FT基因,并证明了FT基因能够抑制CAL蛋白通过泛素蛋白酶体途径的降解。
关 键 词: 植物遗传学;拟南芥;FT;CAL;花原基;分化

Abstract: Flowering Locus T (FT) gene is a critical integrator in the flower signal regulating of higher plants. FT protein initiates the differentiation of floral meristem by activating the expression of floral meristem identity genes. We investigate how FT protein regulates the expression of MADS-box genes Cauliflower (CAL) in the flowering of Arabidopsis. The results show that the early flowering triggered by the overexpression of MADS-box gene CAL is dependent on FT gene. FT can inhibit the degradation of CAL protein via the ubiquitination-proteasome pathway.
