葡萄WRKY家族蛋白在非生物胁迫中的功能探讨

Function Exploration of Grape WRKY Family Proteins Under Abiotic Stresses

干旱、盐和冷害等非生物胁迫严重限制着葡萄产业的发展。WRKY作为一大类转录调控因子,在多种信号转导途径中发挥着重要的作用。随着高通量测序技术及各种研究技术的进步,越来越多的WRKY家族蛋白在非生物胁迫中的功能和作用机制得到验证,为葡萄耐逆机理研究和分子育种筛选优良品种奠定理论基础和提供丰富的候选基因资源。从葡萄WRKY家族蛋白的挖掘和分类、参与植物干旱、盐和冷胁迫非生物胁迫应答机制等方面展开详细论述。

Abiotic stresses caused by drought,salt and cold restrict the development of grape industry. WRKY,as a large transcriptional regulation factor gene family,plays important role in multiple signal-transduction pathways. With the advances in highth roughput sequencing technology and a variety of research techniques,more and more WRKY protein＇s function and mechanism in abiotic stresses have been validated,which establish a theoretical basis and provide a rich candidate gene resources for grape abiotic stress resistant mechanism research and screening excellent varieties through molecular breeding. This review will summarize the identification and classification,drought,salt and cold stresses response mechanism of grape WRKY family proteins in detail.
