图1 调控开花行为的遗传通路(以拟南芥为例)。图中自上而下分为三部分: 上游调控通路、下游开花整合基因和花分生组织基因。虚线方框内代表拟南芥调控开花的6个通路以及相关的基因。方框内的大写字母代表基因的简称, 椭圆框内的字母代表蛋白的简称。带箭头的实线代表促进作用, 平端的虚线代表抑制作用。改自Banta和Purugganan (2011)。

Fig. 1 The genetic pathways regulating flowering (take Arabidopsis thaliana as an example). The figure includes three parts from top to bottom: upstream regulatory pathway, downstream floral integrators and floral meristem identity genes. Six pathways and related genes that regulate flowering in Arabidopsis thaliana are enclosed in the dashed boxes separately. The letters in the boxes stand for abbreviation of genes, and the letters in the ovals stand for abbreviation of proteins. Lines with arrows indicate activation, and broken lines with blunt ends indicate repression. Modified from Banta & Purugganan ( 2011).
