The plant hormone abscisic acid (ABA) regulates many essential processes in growth and development. The recent characterization of ABA-sensitivity mutations in RNA-binding proteins has led to the recognition of a functional link between post-transcriptional mRNA processing and the ABA signal transduction machinery. By influencing transcript abundance, these RNA-binding proteins may modulate ABA signaling through the alteration of mRNA processing events such as splicing, 3' processing, nuclear export, transcript stability and RNA degradation.
植物激素脱落酸（ABA）调控生长和发育中的许多重要过程。近期对RNA结合蛋白中ABA敏感性突变的表征，使人们认识到转录后mRNA加工与ABA信号转导机制之间存在功能联系。通过影响转录本丰度，这些RNA结合蛋白可能通过改变mRNA加工事件（如剪接、3'加工、核输出、转录本稳定性和RNA降解）来调节ABA信号传导。
