Life is full of damaging stresses. Upon injury, plants display various wounding responses including callus formation, activation of defense responses and the establishment of stem cells de novo. Previous studies identified general regulators that orchestrate various physiological responses provoked by tissue injury (Iwase et al., 2011; Iwase et al., 2021). Plants display specific regenerative response in a context-dependent manner, yet molecular and developmental mechanisms that specifically regulate different regenerative responses remain unknown. We recently identified WUSCHEL-RELATED HOMEOBOX 13 (WOX13) as a key regulator of tissue repair and organ adhesion in Arabidopsis thaliana (Ikeuchi et al., 2022; Tanaka et al., 2023). Strikingly, wox13 mutant is totally deficient in organ reconnection in petiole grafting, suggesting that WOX13 is pivotal for the establishment of organ reconnection. We recently found that WOX13 represses other aspects of organ rege neration, implicating that WOX13 may be a specific regulator of diverse regenerative responses.
