摘　　要：干旱是影响许多地区农作物生产力最重要的环境因素之一。向日葵(Helianthus annuus)对干旱条件虽具有耐受性,但其在分子水平上的耐受机制研究较少,阐明向日葵抗旱性的复杂机制将加速抗旱性新品种的选育。本文对参与向日葵干旱胁迫响应的功能基因和转录因子(AP/ERF,bZIP,WRKY,HB,NAC,MYB,bHLH等)进行了总结。最后对当前研究情况进行了总结,并对未来发展趋势进行了展望,希望将这些候选基因和转录因子作为一种潜在的生物技术工具,为今后解析和改良向日葵抗旱性,提高向日葵产量提供参考。Drought is one of the most important environmental factors affecting crop productivity in many regions.Although sunflower(Helianthus annuus)is tolerant to drought conditions,its tolerance mechanisms at the molecular level are less studied.Elucidating the complex mechanisms of drought tolerance in sunflower will accelerate the selection of new drought-resistant varieties.In this paper,functional genes and transcription factors(AP/ERF,bZIP,WRKY,HB,NAC,MYB,bHLH,etc.)involved in drought stress response in sunflower are summarized.Finally,the current research is summarized and the future development trend is given in the hope that these candidate genes and transcription factors can be used as a potential biotechnological tool for future resolution and improvement of drought resistance and yield of sunflower.
