Discovery of a transcription factor necessary for tissue repair and organ reconnection in plants grafting

November 5, 2021

A research group from Niigata University, RIKEN CSRS, National Institute of Advanced Industrial Science and Technology, Meijo University, and Chubu University discovered WOX13, a transcription factor necessary for wound healing and organ reconnection, in Arabidopsis thaliana, a model plant. As WOX13 is also known for cellular reprogramming induced by injury in mosses, this study provides important insights into understanding the evolution of the mechanisms that regulate injury response and organ regeneration. The results of this study are expected to be applied in agriculture, especially in the development of new grafting techniques.
