Box 1 figure from Kim and Seo: Recent developments in our understanding of early wound signaling in the control of DNRR. This schematic represents the key contributions of wound-responsive defense hormones to the DNRR process. Their molecular signaling pathways are graphically summarized in panels A–E. (A) Yan et al. (2023) introduced the key role of the cell wall–localized IRR1 peroxidase in DNRR. (B) Hernández-Coronado et al. (2022) and Tran et al. (2023a) described the trade-off between SA-regulated defense responses and regeneration, which may be conserved across various plant species. (C) Lee et al. (2024) showed that the wound-responsive ESR1 transcription factor strongly promotes ASA1 expression immediately after wounding via its dual mode of action. (D) Veloccia et al. (2016), Li et al. (2020), and Shin et al. (2023) revealed that ethylene regulates DNRR in a stage-specifc manner. (E) Liu et al. (2022) showed that JA, ethylene, ROS, and SA are rapidly activated upon wounding
