摘要:
大豆是重要的油料作物,在生长发育过程中易遭受各种胁迫影响而造成产量和品质损失。在作物响应逆境胁迫的研究中,多数报道已证明WRKY转录因子(Transcription factors, TFs)可以通过调节植物激素信号转导等途径来介导作物响应各种胁迫。WRKY转录因子家族是植物界众多TFs家族中的一种,包含一个或两个WRKY结构域,约60个氨基酸组成,主要参与作物的衰老、种子的发育、萌发和休眠等生物学过程,进而调节植物对生物和非生物胁迫的适应性,但其在大豆研究中的系统性相对不足。本文主要阐述了大豆WRKY转录因子家族结构、调节大豆响应生物和非生物胁迫方面的研究进展,展望了WRKY家族未来研究方向和热点,旨在为进一步拓展和深化大豆WRKY基因家族生物学功能有针对性的开发利用提供理论基础。

Abstract:
Soybean is an important oil crop and is often challenged by multiple stresses, thus resulting in loss of yield production and decrease of grain quality in lifecycle. WRKY transcription factors (TFs) are identified to involve into the responses to various stresses, for instance by regulating phytohormone-mediated signal transduction. The WRKY transcription factors belong to one of the TF families found in plants. The family member generally contains one or two WRKY domain(s) which consists of approximately 60 amino acids. WRKY-TFs have been uncovered participating into the biological processes such as crop senescence, seed development, germination and dormancy, and have been also found to regulate the adaptability of plants response upon biotic and abiotic stresses. However, deciphering WRKY-TFs in soybean remains relatively insufficient. This study mainly elaborates on the research progress of the family structure/organization and their roles responding to biotic and abiotic stresses. Moreover, we propose future research focuses and hot spots to provide insights for unlocking the biological function of the WRKY family members in soybean.
Key words:  soybean  WRKY transcription factor  biotic stress  abiotic stress
