摘　　要：植物经常面临不利的生长条件,如干旱、盐分、寒冷、冰冻和高温。这些胁迫会延误生长和发育,降低生产率,在极端情况下甚至导致植物死亡。植物对胁迫的响应是动态的并涉及不同调控水平间的复杂交互应答,包括生理和形态学适应的基因表达和新陈代谢的调节。总结响应干旱、极端温度和盐分胁迫的代谢变化信息。Plants regularly face adverse growth conditions, such as drought, salinity, chilling, freezing, and high temperatures. These stresses can delay growth and development, reduce productivity, and, in extreme cases, cause plant death. Plant stress responses are dynamic and involve complex cross-talk between different regulatory levels, including adjustment of metabolism and gene expression for physiological and morphological adaptation. In this review, information about metabolic changes in response to drought, extreme temperature, and salinity stress were summarized.
