Abstract Necroptosis has recently been identified as an alternative form of programmed cell death that is characterized by defined molecular mechanisms. Reactive oxygen species (ROS) are involved in the regulation of numerous signaling pathways, as they are highly reactive and can cause (ir)reversible posttranslational modifications. While the role of ROS in other modes of cell death has been extensively studied, its impact on necroptotic signaling and cell death is far less clear. The current minireview discusses the evidence for and against a role of ROS in necroptosis.

The Relationship

Programmed cell death (PCD) plays crucial roles in plant development and defence response. Reactive oxygen species (ROS) are produced during normal plant growth, and high ROS concentrations can change the antioxidant status of cells, leading to spontaneous cell death. In addition, ROS function as signalling molecules to improve plant stress tolerance, and they induce PCD under different conditions. This review describes the mechanisms underlying plant PCD, the key functions of mitochondria and chloroplasts in PCD, and the relationship between mitochondria and chloroplasts during PCD. Additionally, the review discusses the factors that regulate PCD. Most importantly, in this review, we summarise the sites of production of ROS and discuss the roles of ROS that not only trigger multiple signalling pathways leading to PCD but also participate in the execution of PCD, highlighting the importance of ROS in PCD.
