摘要
受全球工业化和气候变化的影响,具有固着生长特性的植物面临着多种非生物逆境的威胁,而种子在各类非生物逆境胁迫下的顺利萌发,对植物的繁殖与地理分布、作物的产量与质量等极其重要。随着植物分子生物学研究的不断深入,非生物逆境协迫下种子萌发的调控机制研究取得了诸多进展。本文重点综述了在盐胁迫、极端温度(高温和低温)胁迫、干旱胁迫、荫蔽胁迫、渗透胁迫和淹涝胁迫等非生物逆境胁迫下,植物通过介导激素、活性氧及能量代谢通路调控种子萌发的分子机制,并讨论了三大通路之间的互作,展望了未来该领域的研究热点,以期总结种子萌发过程中响应非生物逆境胁迫的主要调节模块/基因功能,为农业生产及环境改造中的育种设计提供参考。
Under the influence of complex global climate change and industrial globalization,plants with fixed growth characteristics face the threats of diverse abiotic stresses.The successful germination of seeds under various abiotic stresses is of great important for plant reproduction,geographical distribution,crop yield and quality.With the development of plant molecular biology,significant progress has been achieved in the regulatory mechanisms of seed germination under abiotic stresses.In this review,the molecular mechanisms of regulating seed germination under salt stress,extreme temperature stress(high and low temperatures),drought stress,shade stress,osmotic stress and waterlogging stress were summarized in terms of phytohormone,reactive oxygen species(ROS)and energy metabolism pathways.The crosstalk network among these cascades and the potential research hotspots in this field were discussed,so as to elucidate the main modulators/gene functions in response to abiotic stresses during seed germination,and provide references for breeding design in agricultural production and environmental modification.
