Summary Reactive oxygen species (ROS) are among the most important signaling molecules, playing a significant role in plant growth, development, and responses to various environmental stresses. Respiratory burst oxidase homologs (RBOHs) key enzymes ROS production. Plants tightly regulate activation deactivation of RBOHs through post‐translational modifications (PTMs), including phosphorylation, ubiquitination, S ‐nitrosylation, persulfidation. These PTMs fine‐tune production, ensuring normal growth development while facilitating rapid abiotic biotic This review discusses effects different on RBOH function their biological relevance. Additionally, we examine evolutionary conservation PTM sites emphasize complex interplay between multiple regulating RBOHs.

Abstract Oxygen deficiency (hypoxia) occurs naturally in many developing plant tissues but can become a major threat during acute flooding stress. Consequently, plants as aerobic organisms must rapidly acclimate to hypoxia and the associated energy crisis ensure cellular ultimately organismal survival. In plants, oxygen sensing is tightly linked with oxygen-controlled protein stability of group VII ETHYLENE-RESPONSE FACTORs (ERFVII), which, when stabilized under hypoxia, act key transcriptional regulators hypoxia-responsive genes (HRGs). Multiple signaling pathways feed into fine-tune decision-making First, ATP shortage upon directly affects status adjusts anaerobic metabolism. Secondly, altered redox homeostasis leads reactive nitrogen species (ROS RNS) accumulation, evoking oxidative stress acclimation. Finally, phytohormone ethylene promotes improve acclimation, while turn alter ethylene, auxin, abscisic acid, salicylic jasmonate guide development responses. this Update, we summarize current knowledge on how energy, redox, hormone are induced subsequently integrated at molecular level stress-tailored We show that some HRGs responsive changes independently status, propose an updated HRG list more representative for marker gene expression. discuss synergistic effects their phenotypic consequences context both environmental developmental hypoxia.
