The roles of flavonoids in plant defence against pathogens, herbivores, and environmental stress are reviewed and their significant contribution to plant resistance is discussed. The induction of flavonoids is of particular interest for gathering evidence of their roles. Tools are mentioned which may enhance flavonoid biosynthesis and accumulation. These include metabolic engineering and UV light. The induction of defence-related flavonoids is modified by other determining factors and competition between growth and secondary metabolism may exist. In an evolutionary context, stress-related oxidative pressure may have been a major trigger for the distribution and abundance of flavonoids. UV protection is one of their most significant, or even the most significant, functional role for flavonoids. The multi-functionality of these compounds, however, often complicates the interpretation of experimental results but, overall, it supports the importance of flavonoids.
本文综述了黄酮类化合物在植物抵御病原体、食草动物和环境胁迫中的作用，并讨论了它们对植物抗性的重要贡献。黄酮类化合物的诱导作用对于收集其作用证据尤为重要。文中提到了一些可能增强黄酮类化合物生物合成和积累的工具，包括代谢工程和紫外线。防御相关黄酮类化合物的诱导会受到其他决定性因素的影响，并且生长与次生代谢之间可能存在竞争。在进化背景下，与胁迫相关的氧化压力可能是黄酮类化合物分布和丰度的主要触发因素。紫外线防护是黄酮类化合物最重要的功能之一，甚至可能是其最主要的功能。然而，这些化合物的多功能性常常使实验结果的解释变得复杂，但总体而言，这支持了黄酮类化合物的重要性。
