Mechanisms underlying vascular regeneration in damaged aerial organs

The article by Radhakrishnan et. al. ( is featured in Development issue 147 (6) and is selected as one of the Research Highlights, where it shows that PLT-CUC2 regulatory module acts in a coherent feed-foreword loop to increase the local auxin production in response to injury. This instructs polarization and fate specification guiding the regenerating vein to its destination.
