Abiotic and biotic stress conditions lead to production of reactive carbonyl species (RCS) which are lipid peroxide derivatives and have detrimental effects on plant cells especially at high concentrations. There are several molecules that can be classified in RCS; among them, 4-hydroxy-(E)-2-nonenal (HNE) and acrolein are widely recognized and studied because of their toxicity. The toxicity mechanisms of RCS are well known in animals but their roles in plant systems especially signaling aspects in metabolism need to be addressed. This chapter focuses on the production mechanisms of RCS in plants as well as how plants scavenge and modify them to prevent irreversible damage in the cell. We aimed to get a comprehensive look at the literature to summarize the signaling roles of RCS in plant metabolism and their interaction with other signaling mechanisms such as highly recognized reactive oxygen species (ROS) signaling. Changing climate promotes more severe abiotic stress effects on plants which also decrease yield on the field. The effects of abiotic stress conditions on RCS metabolism are also gathered in this chapter including their signaling roles during abiotic stresses. Different methods of measuring RCS in plants are also presented in this chapter to draw more attention to the study of RCS metabolism in plants.
非生物和生物胁迫条件会导致活性羰基物质（RCS）的产生，这些物质是脂质过氧化物的衍生物，对植物细胞，尤其是在高浓度下具有有害影响。有几种可以归类为 RCS 的分子；其中，4-羟基-（E）-2-壬烯醛（HNE）和丙烯醛由于其毒性而被广泛认可和研究。RCS 在动物中的毒性机制是众所周知的，但它们在植物系统中的作用，特别是在代谢中的信号方面，需要加以解决。本章重点介绍了植物中 RCS 的产生机制，以及植物如何清除和修饰它们，以防止细胞内发生不可逆转的损伤。我们旨在全面查阅文献，总结 RCS 在植物代谢中的信号作用及其与其他信号机制（如高度认可的活性氧（ROS）信号）的相互作用。气候变化加剧了植物的非生物胁迫效应，也降低了田间的产量。本章还收集了非生物胁迫条件对 RCS 代谢的影响，包括它们在非生物胁迫期间的信号作用。本章还介绍了植物中 RCS 的不同测量方法，以引起对植物 RCS 代谢研究的更多关注。
