“…A superoxide anion with higher oxidizing activity than H 2 O 2 is also required for plant salt stress responses. A recent study demonstrated that O 2 • ¯ inhibits MhCAT2 (catalase 2 of Malus hupehensis ) activity via oxidative modification of its His‐225 residue to increase H 2 O 2 levels for salt stress tolerance, providing a posttranslational brake mechanism for the excessive scavenging of H 2 O 2 caused by salt‐induced overaccumulation of CAT (Yang et al, 2023).…”

Reactive oxygen species (ROS) are produced as undesirable by‐products of metabolism in various cellular compartments, especially in response to unfavorable environmental conditions, throughout the life cycle of plants. Stress‐induced ROS production disrupts normal cellular function and leads to oxidative damage. To cope with excessive ROS, plants are equipped with a sophisticated antioxidative defense system consisting of enzymatic and non‐enzymatic components that scavenge ROS or inhibit their harmful effects on biomolecules. Nonetheless, when maintained at relatively low levels, ROS act as signaling molecules that regulate plant growth, development, and adaptation to adverse conditions. Here, we provide an overview of current approaches for detecting ROS. We also discuss recent advances in understanding ROS signaling, ROS metabolism, and the roles of ROS in plant growth and responses to various abiotic stresses.This article is protected by copyright.

“…CAT plays an important role in physiological processes, such as plant growth and development, stress response, defense response, and delaying plant age [5,6]. It mainly clears photorespiration, mitochondrial electron transfer, and β-hydrogen peroxide generated during fatty acid oxidation and other processes to prevent damage caused by reactive oxygen species to plants [7]. Enhancing CAT enzyme activity can reduce the accumulation of reactive oxygen species, thereby improving plant antioxidant capacity, which is of great significance for plant resistance to biotic and abiotic stresses.…”

Catalases (CATs) play crucial roles in scavenging H2O2 from reactive oxygen species, controlling the growth and development of plants. So far, genome-wide identification and characterization of CAT genes in oil palm have not been reported. In the present study, five EgCAT genes were obtained through a genome-wide identification approach. Phylogenetic analysis divided them into two subfamilies, with closer genes sharing similar structures. Gene structure and conserved motif analysis demonstrated the conserved nature of intron/exon organization and motifs among the EgCAT genes. Several cis-acting elements related to hormone, stress, and defense responses were identified in the promoter regions of EgCATs. Tissue-specific expression of EgCAT genes in five different tissues of oil palm was also revealed by heatmap analysis using the available transcriptome data. Stress-responsive expression analysis showed that five EgCAT genes were significantly expressed under cold, drought, and salinity stress conditions. Collectively, this study provided valuable information on the oil palm CAT gene family and the validated EgCAT genes can be used as potential candidates for improving abiotic stress tolerance in oil palm and other related crops.
