Abstract excerpt
Plant secondary growth is driven by 2 concentric meristems: the inner vascular cambium and outer cork cambium. The periclinal cell divisions of both meristems, providing thickness and protection to plant organs, are activated with a delay after the primary development. Cytokinins and a set of downstream transcription factors are key players in promoting transition from primary to secondary development; however,...
