florigen

Florigen , or the flowering hormone , has been sought by many researchers .

许多研究者都在寻找成花素或开花激素。

Following locus T ( FT ) gene as a " florigen ", one of the flowering-time genes , can activate floral meristem feature genes and induce flowering .

FollowinglocusT（FT）基因在拟南芥和瓜类等植物中被证明为成花素类物质，决定着开花时间，可激活花分生组织特征基因，诱导植物开花。

Recent molecular genetics studies have revealed a genetic network that enables the critical daylength response of florigen gene expression .

近来分子遗传研究揭示了一个遗传网络可以使成花素基因对临界日长做出应答。

Plant FLOWERING LOCUS T ( FT ) homologous gene plays a important role in the flower forming . Recently FT protein has been proved to be florigen .

植物FloweringlocusT（FT）同源基因在成花过程中起着关键作用，最近FT蛋白已经被证明是开花素。

Here , we revealed multiple action points for each phytochrome in the critical daylength response of florigen expression by using single and double phytochrome mutant lines of rice .

本研究通过水稻光敏色素单突变和双突变株系，揭示了不同光敏色素在成花素基因应答日照长度的过程的多种作用。

Therefore , each phytochrome gene of rice has distinct roles , and all of the phytochrome actions coordinately control the critical daylength response of florigen expression in rice .

因此，水稻中每个光敏色素基因都有着独特的作用，这些光敏色素协同调控水稻成花素基因的表达对临界日长的应答。
