摘　　要：UV-B(ultraviolet-B)辐射会在多个方面对植物产生影响,随着研究的不断深入,人们发现UV-B除了作为一个胁迫因子外,还会作为信号调节因子来调节植物的生长发育.本文把UV-B辐射对植物形态建成和生理代谢的影响、植物响应UV-B辐射的信号通路以及UV-B与其他因子复合作用对植物的影响等进行了论述,并对植物响应UV-B辐射的研究做了展望.UV-B radiation severely affects plant growth and development.Here,we summarized the influences of UV-B radiation on plant in several aspects,including morphogenesis,metabolisms,UV-B responsive signaling pathways and the comprehensive effects of UV-B combined with other environmental factors.Problems remaining to be solved were discussed as well.
