Abstract：
Phenolic compounds are a group of secondary metabolites responsible for several processes in plants-these compounds are involved in plant-environment interactions (attraction of pollinators, repelling of herbivores, or chemotaxis of microbiota in soil), but also have antioxidative properties and are capable of binding heavy metals or screening ultraviolet radiation. Therefore, the accumulation of these compounds has to be precisely driven, which is ensured on several levels, but the most important aspect seems to be the control of the gene expression. Such transcriptional control requires the presence and activity of transcription factors (TFs) that are driven based on the current requirements of the plant. Two environmental factors mainly affect the accumulation of phenolic compounds-light and temperature. Because it is known that light perception occurs via the specialized sensors (photoreceptors) we decided to combine the biophysical knowledge about light perception in plants with the molecular biology-based knowledge about the transcription control of specific genes to bridge the gap between them. Our review offers insights into the regulation of genes related to phenolic compound production, strengthens understanding of plant responses to environmental cues, and opens avenues for manipulation of the total content and profile of phenolic compounds with potential applications in horticulture and food production.
摘要：
酚类化合物是一组次级代谢产物，负责植物中的几个过程-这些化合物参与植物与环境的相互作用（传粉媒介的吸引，驱除食草动物，或土壤中微生物群的趋化性)，而且还具有抗氧化性能，能够结合重金属或屏蔽紫外线辐射。因此,这些化合物的积累必须被精确地驱动，这在几个层面上得到了保证，但最重要的方面似乎是基因表达的控制。这种转录控制需要转录因子(TF)的存在和活性,其基于植物的当前需求而被驱动。主要影响酚类化合物积累的两个环境因子——光照和温度。由于已知光感知是通过专门的传感器（光感受器）发生的，因此我们决定将有关植物光感知的生物物理知识与有关特定基因转录控制的基于分子生物学的知识相结合，以弥合它们之间的差距。我们的评论提供了与酚类化合物产生相关的基因调控的见解，加强对植物对环境线索的反应的理解，并为操纵酚类化合物的总含量和概况开辟了途径，并在园艺和食品生产中具有潜在的应用。
