摘 要:

ERF (ethylene responsive factor)转录因子是植物AP2/ERF转录因子超家族的一个亚家族, 其特征是蛋白序列中含有一 个高度保守的58或59个氨基酸组成的ERF结构域, 广泛参与植物生长发育及各种逆境胁迫反应的调控。文章简要介绍ERF 转录因子在植物抗生物和非生物胁迫反应中的作用及其可能机制, 并讨论了今后的研究重点。

Abstract:

The ethylene responsive factors (ERF) belong to a subfamily of the AP2/ERF superfamily in plants. The ERF family was defined by the presence of a conserved ERF domain consisting of 58 or 59 amino acids and has been demonstrated to be widely involved in regulation of various aspects of plant growth and development as well as in responses to different abiotic and biotic stresses. In this minireview, we summarize the functions and mechanisms of the ERF transcription factors in regulation of responses to abiotic and biotic stresses and discuss the future directions of studies on the ERF transcription factors in plants.

Key words: ERF transcription factor; disease resistance; abiotic stress tolerance; mechanism
