Solar UV-B radiation reaching the Earth's surface is continually increased due to the stratospheric ozone layer depletion. UV-B radiation has been shown to have mutagenic effects damaging DNA, proteins and membranes. During evolution plants developed systems for UV-B perception and effective defense mechanisms. In this review the main UV-B effects, cytophysiological responses of plants and their interactions with microorganisms are analyzed. UV-B-induced signal transduction pathways in plant cells are discussed.
由于平流层臭氧层损耗，到达地球表面的太阳UV-B辐射持续增加。UV-B辐射已被证明具有诱变作用，会损害DNA、蛋白质和细胞膜。在进化过程中，植物形成了UV-B感知系统和有效的防御机制。在这篇综述中，分析了UV-B的主要影响、植物的细胞生理反应及其与微生物的相互作用。还讨论了植物细胞中UV-B诱导的信号转导途径。
