Abstract

Abstract:

Rice often encounters various abiotic stresses (including drought, high salt, low temperature, high temperature, etc.) and biotic stresses (such as pests and diseases) during its growth process, which seriously affect its normal growth and development. The WRKY transcription factor farmily, one of the largest families of transcription factors in plants, plays a key role in regulating plant growth and development as well as in responding to abiotic and biotic stresses. This paper reviews the structural characteristics of WRKY transcription factors and their application progress in genetic engineering for rice resistance to abiotic stresses (drought, high salt, low temperature, high temperature, etc.) and biotic stresses (rice blast, bacterial leaf blight, sheath blight, rice planthopper, etc.), aiming to provide a theoretical basis and practical guidance for the application of WRKY transcription factor in the genetic improvement of stress tolerance in rice and other crops.

Key words: rice, WRKY transcription factor, drought, high salinity, temperature stress, rice blast, bacterial leaf blight, sheath blight, rice planthopper

摘要：

水稻在其生长过程中经常面临各种非生物胁迫（包括干旱、高盐度、低温及高温等）和生物胁迫（如病虫害），严重影响其正常生长发育。WRKY转录因子家族作为植物界中最为庞大的转录因子家族之一，在调控植物生长发育及应对非生物胁迫和生物胁迫方面发挥着关键作用。本文综述了WRKY转录因子的结构特点及其在水稻抗非生物胁迫（干旱、高盐、低温、高温等）、生物胁迫（稻瘟病、白叶枯病、纹枯病、稻飞虱等）基因工程中的应用进展，旨在为WRKY转录因子在水稻及其他作物抗逆性遗传改良中的应用提供理论基础和实践指导。
