Auxin signalling plays a key role in various developmental processes ranging from embryogenesis to senescence in plants. Auxin response factor (ARF), a key component of auxin signalling, functions by binding to auxin response element within promoter of auxin response genes, activating or repressing the target genes. Increasing evidences show that ARFs are crucial for plant response to stresses. This review summarises the recent advance on the functions and their regulatory pathways of rice ARFs in development and responding to stresses. The importance of OsARFs is demonstrated by their roles in triggering various physiological, biochemical and molecular reactions to resist adverse environmental conditions. We also describe the transcriptional and post-transcriptional regulation of OsARFs, and discuss the major challenges in this area.
生长素信号传导在植物从胚胎发生到衰老的各种发育过程中起着关键作用。生长素响应因子（ARF）是生长素信号传导的关键组成部分，通过与生长素响应基因启动子内的生长素响应元件结合来发挥作用，激活或抑制靶基因。越来越多的证据表明，ARF对植物应对胁迫至关重要。本综述总结了水稻ARF在发育和应对胁迫方面的功能及其调控途径的最新进展。OsARF在触发各种生理、生化和分子反应以抵抗不利环境条件方面的作用证明了它们的重要性。我们还描述了OsARF的转录和转录后调控，并讨论了该领域的主要挑战。
