Herbaceous and woody plants display specific mechanisms allowing them to adapt and survive to a broad variety of environmental stresses. Nevertheless, all plant species share certain basic physiological and biochemical mechanisms. Under both abiotic and biotic challenges, the extent to which reactive oxygen species (ROS) accumulate relies on the antioxidative system, which is in charge to maintain cellular homeostasis and prevent ROS damage. Moreover, a tight control of ROS production is crucial so that they perform their signalling function. Thus, antioxidative metabolism and redox biology are key players in the physiological response to stress. However, little attention has been paid to the overlapping mechanisms and convergent pathways of antioxidant metabolism between abiotic and biotic stress responses. In the present review, the responses of an herbaceous plant (Pisum sativum L.) and a woody plant (Prunus persica L.) against two forms of stress—salinity and infection by Plum pox virus—were compared, placing emphasis on common response patterns. This information may serve to devise agronomic approaches conferring stress tolerance to many economically relevant crops.

生物和非生物胁迫反应在哪里收敛：豌豆和桃子植物对盐度和梅花病毒感染的响应的常见模式

草本植物和木本植物显示出特定的机制，使它们能够适应各种环境胁迫并在其中生存。尽管如此，所有植物物种都有某些基本的生理和生化机制。在非生物和生物挑战下，活性氧（ROS）积累的程度取决于抗氧化系统，该系统负责维持细胞体内稳态并防止ROS损伤。此外，严格控制ROS的产生至关重要，因此它们可以执行其信号传导功能。因此，抗氧化代谢和氧化还原生物学是对压力的生理反应的关键参与者。然而，很少有人关注非生物和生物应激反应之间抗氧化剂代谢的重叠机制和收敛途径。在目前的评论中，比较了两种（Pisum sativum L.）和木本植物（Prunus persica L.）对盐分和梅花痘病毒感染的胁迫，着重强调了常见的响应方式。该信息可能有助于设计赋予许多经济相关农作物抗逆性的农艺方法。
