Herbicides are small molecules that act by inhibiting specific molecular target sites within primary plant metabolic pathways resulting in catastrophic and lethal consequences. The stress induced by herbicides generates reactive oxygen species (ROS), but little is known about the nexus between each herbicide mode of action (MoA) and their respective ability to induce ROS formation. Indeed, some herbicides cause dramatic surges in ROS levels as part of their primary MoA, whereas other herbicides may generate some ROS as a secondary effect of the stress they imposed on plants. In this review, we discuss the types of ROS and their respective reactivity and describe their involvement for each known MoA based on the new Herbicide Resistance Action Committee classification.
除草剂是通过抑制初级植物代谢途径中的特定分子靶标位点而起作用的小分子，从而导致灾难性和致命的后果。除草剂引起的应激会产生活性氧（ROS），但对于每种除草剂作用模式（MoA）与它们各自诱导 ROS 形成的能力之间的联系知之甚少。事实上，一些除草剂作为其主要 MoA 的一部分会导致 ROS 水平急剧上升，而其他除草剂则可能会由于它们对植物造成的应激而产生一些 ROS。在这篇综述中，我们讨论了 ROS 的类型及其各自的反应性，并根据新的除草剂抗性行动委员会分类描述了它们在已知的每种 MoA 中的参与情况。
