RBE与microRNA 319共同调控拟南芥中TCP 4基因的转录，从而调控花瓣的生长。植物器官生长需要从细胞增殖到细胞扩增和分化的适当过渡。CIN-TCP转录因子基因TCP 4及其转录后调节因子microRNA 319在这一过程中起着关键作用。在这项研究中，我们确定了C2 H2锌指基因兔耳（RBE）的产品调节TCP 4的转录在拟南芥（拟南芥）花瓣发育的途径。在花瓣发育的早期阶段，RBE直接抑制TCP 4;这有助于RBE在控制花瓣原基生长中的作用。我们还发现rbe-1突变体强烈增强了tcp 4soj 6和mir 319 a的花瓣表型，这两种突变体具有受损的miR 319对TCP 4的调节。我们的研究结果表明，转录和转录后调节功能一起模式的空间和时间表达的TCP 4。这反过来又控制了拟南芥花瓣的大小和形状。
RBE functions with microRNA319 to control the growth of petals by regulating the transcription of TCP4 in Arabidopsis. Plant organ growth requires the proper transition from cell proliferation to cell expansion and differentiation. The CIN-TCP transcription factor gene TCP4 and its post-transcriptional regulator microRNA319 play a pivotal role in this process. In this study, we identified a pathway in which the product of the C2H2 zinc finger gene RABBIT EARS (RBE) regulates the transcription of TCP4 during Arabidopsis (Arabidopsis thaliana) petal development. RBE directly represses TCP4 during the early stages of petal development; this contributes to the role of RBE in controlling the growth of petal primordia. We also found that the rbe-1 mutant strongly enhanced the petal phenotypes of tcp4soj6 and mir319a, two mutants with compromised miR319 regulation of TCP4. Our results show that transcriptional and post-transcriptional regulation function together to pattern the spatial and temporal expression of TCP4. This in turn controls petal size and shape in Arabidopsis.
