Abstract

AUXIN RESPONSE FACTOR3 (ARF3), one of the auxin response factors family of transcription factors, is well characterized by its functions in polarity identification and organ patterning. We recently demonstrated that ARF3 plays important roles in floral meristem (FM) maintenance and termination by regulating cytokinin biosynthesis and signaling. However, the relationship of its multiple roles in differently developmental stage is still unclear. Here, we present data that ARF3 plays distinct roles during early flower development that are different from its roles in organ polarity determination and pattering. Thus, our findings shed light on the functional diversity of one specific transcription factor in plant development.

摘要

生长素响应因子3(ARF3)是转录因子生长素响应因子家族的成员之一,因其在极性识别和器官模式形成中的功能而得到充分表征。我们最近证明,ARF3通过调节细胞分裂素的生物合成和信号传导,在花分生组织(FM)的维持和终止中发挥重要作用。然而,其在不同发育阶段的多种作用之间的关系仍不清楚。在这里,我们提供的数据表明,ARF3在花发育早期发挥着与器官极性确定和模式形成不同的独特作用。因此,我们的研究结果揭示了一种特定转录因子在植物发育中的功能多样性。
