摘要
拟南芥胚后发育经历了营养生长和生殖生长两个主要阶段,在营养生长的过程中,由幼龄期向成熟期的转变称为营养生长时相转变。有关这个转变的基因调控网络仍不清楚。本文对拟南芥晚花突变体fca-1、fve-1的营养生长时相转变过程进行了形态学观察和基因表达分析。结果表明:与野生型相比,fve-1、fca-1植株幼龄期延长,导致营养生长时相转变延迟。自主开花基因FVE、FCA参与了植物营养生长时相转变的调控。
Post-embryo development of Arabidopsis thaliana undergoes two main stages, namely,vegetative and reproductive growth phase. The change in vegetative growth from juvenile to adult refers to vegetative phase change. The gene network of regulating vegetative phase change remains unclear. In this paper, morphological observation and gene expression are performed to analyze the vegetative phase change in two late-flowering mutants, namely, fca-1 and fve-1. The results showed that compared with the wild type Ler, both vegetative phase change and blossoming in fca-1 and fve-1 mutants are delayed.And this cause the vegetative phase change delay. Autonomous pathway related gene FVE and FCA of flowering time of Arabidopsis thaliana can regulate the vegetative phase change.
