Although UV-B accounts for <0.5% of total sunlight energy reaching the earth's surface, however, it has multifaceted impact on plants as well as animals. High energy UV-B radiation is reported to have damaging impact on plant growth and productivity. After discovery of UV RESISTANCE LOCUS8 (UVR8), perceptions of biological impact of UV-B radiation on plants, have changed dramatically in last few years. This review focuses on the changing concept about the role of UV-B from a generic stressor to a specific regulator in plant science and has tried compiling the historical aspects of UVR8 starting with discovery, localisation and regulatory role played by UVR8 and also its interaction with other regulators.
虽然到达地球表面的太阳光能量中紫外线B(UV-B)占比不到0.5%,然而,它对植物和动物都有多方面的影响。据报道,高能量的UV-B辐射对植物生长和生产力具有破坏性影响。自发现紫外线抗性位点8(UVR8)后,在过去几年里,人们对UV-B辐射对植物的生物学影响的认识发生了巨大变化。这篇综述聚焦于植物科学领域中UV-B从一般应激源到特定调节因子角色的概念转变,并尝试梳理UVR8的历史脉络,从其发现、定位、发挥的调节作用以及与其他调节因子的相互作用开始阐述。
