Research Progress in Molecular Mechanisms of Drought Resistance in Potatoes

摘要

马铃薯是全球第四大粮食作物，也是中国主要的粮食作物，在保障粮食安全方面有重要作用。随着全球气候变暖，干旱成为农业生产上频发的自然灾害，严重制约马铃薯生产。从干旱胁迫信号传导、转录因子、渗透调节等方面综述了马铃薯抗旱机制，从多组学发展角度论述了提高马铃薯抗旱性的途径与措施，对马铃薯耐旱研究方向及方法进行展望，为后续马铃薯抗旱机制研究及优良品种选育提供参考。

Abstract

Potato is the fourth largest food crop in the world and also a major food crop in China. It plays a significant role in ensuring food security. With global warming, drought has become a frequent natural disaster in agricultural production, seriously restricting potato production. The mechanism of drought resistance in potato was reviewed from the aspects of signal transduction, transcription factors and osmotic regulation, and the approaches and measures to improve drought resistance in potato were discussed from the aspects of the development of multi-omics. Furthermore, the research direction and methods of potato drought tolerance were prospected. This review would provide reference for further study of potato drought resistance mechanism and breeding of improved varieties.
