基于CiteSpace解析高温干旱对植物生长代谢的影响研究

CiteSpace-based Analysis of the Effects of High Temperature and Drought on Plant Growth and Metabolism

全球气温升高导致大部分地区高温与干旱胁迫同时发生的风险增加。高温和干旱胁迫同时发生将严重影响植物生长发育,造成作物产量损失及树木死亡。2013以来,收录于Web of Science核心合集数据库中的关于高温干旱复合胁迫的研究文献共306篇。本研究运用CiteSpace软件,分析其主要的研究热点,并通过关键词确定近十年高温干旱复合胁迫研究的主要内容。在此基础上,进一步围绕热点和主要内容深入解析高温干旱复合胁迫对植物生理、代谢和分子调控等方面的影响。本综述通过整合近年一系列增强植株胁迫耐受性的文献,包括转基因技术、胁迫引发、接种菌根、施加营养元素和植物激素等,阐明逆境胁迫对植物的不利影响,为了解和开发复合胁迫耐受性品种以及提高植物对未来气候变化的适应能力奠定基础。

Rising global temperatures have increased the risk of simultaneous occurrence of heat and drought stress in most regions.The simultaneous occurrence of high temperature and drought stress will seriously affect plant growth and development,resulting in crop yield loss and tree mortality.Since 2013,a total of 306 research papers on high temperature and drought combined stress have been included in the Web of Science Core Collection database.In this study,we used CiteSpace software to analyze its main research hotspots and identify the main content of high temperature and drought compound stress research in the last decade by keywords.On this basis,the effects of hightemperature and drought stress on plant physiology,metabolism and molecular regulation were further analyzed around the hotspots and main contents.This review elucidates the adverse effects of adversity stress on plants by integrating a series of literature on enhancing plant stress tolerance in recent years,including transgenic technology,stress initiation,inoculation of mycorrhizae,application of nutrients and phytohormones,etc.,and lays the foundation for understanding and developing compound stress-tolerant varieties as well as improving the adaptive capacity of plants to future climate change.
