Earlier, Ultraviolet-B (UV-B) radiations were considered to be detrimental to plant cells and their components. But recent researches have shown that it has multifaceted impacts on plants. The discovery of UV-B RESISTANCE 8 (UVR8) photoreceptors has changed the perceptions of its biological impact. They are significant regulators of plant morphogenesis, growth, and secondary metabolite production. UV-B radiations when provided in low intensity can be used to generate improved biotic and abiotic stress-tolerant plants with secondary metabolite enriched plant products. Deciphering the extensive role of plant transcription factors for the enzyme that encodes genes for the construction of the plant secondary metabolite network in response to UV-B has appeared to be useful in the plant signaling cascades and in understanding its regulatory role towards secondary metabolite biosynthesis. This review highlights the role UV-B regulated transcriptional factors involved in plant morphogenesis, signaling, and plant secondary metabolite production.

早些时候，紫外线-B (UV-B) 辐射被认为对植物细胞及其成分有害。但最近的研究表明，它对植物有多方面的影响。UV-B RESISTANCE 8 (UVR8) 光感受器的发现改变了对其生物影响的看法。它们是植物形态发生、生长和次生代谢产物产生的重要调节剂。当以低强度提供时，UV-B 辐射可用于产生具有富含次生代谢物的植物产品的改良的生物和非生物胁迫耐受性植物。解读植物转录因子对编码基因的酶的广泛作用，用于构建植物次生代谢物网络以响应 UV-B 似乎在植物信号级联和理解其对次生代谢物生物合成的调节作用中很有用。这篇综述强调了 UV-B 调节转录因子在植物形态发生、信号传导和植物次生代谢产物生产中的作用。
