摘　要：

本文根据国内外最新研究成果详细介绍了几种模式植物、果树、蔬菜、花卉、粮食作物、林木等植物生长素响应因子(ARF)基因家族的鉴定、分子结构、信号转导机制、时空表达模式以及ARF在生长发育中的生物学功能, 并在不同物种ARF家族间进行了多方面比较, 以期总结出ARF家族共有的特征和差异, 为揭示ARF在植物生长发育中的调控机制提供参考。综述相关研究表明, ARF在信号转导途径中受光信号、生长激素、环境条件、microRNA及ta-siRNA等的变化影响植物的内源性反应, 从而调控植物的生长发育。最后, 分析了在植物ARF研究中存在的问题, 并对其未来研究方向进行了展望。

Abstract:

This paper reviews the identification, molecular structure, signal transduction mechanism, temporal and spatial expression patterns of auxin response factor (ARF) gene family, based on the latest research in several model plants, fruit trees, vegetables, flowers, grain crops, woody plants, and so forth. ARFs of these species are also compared, analyzed and summarized to explore the common characteristics and differences of ARF families, which could provide references for discovering the regulatory mechanisms of ARF in plant growth and development. It was found that the changes in light signal, growth hormone, environmental conditions, microRNA and trans-acting small interfering RNA (ta-siRNA) in ARF signal transduction affected the endogenous responses of plants, thus regulating the plant growth and development. Finally, we discuss the existing problems in the research on plant ARF, and prospects for future research.
