Fig. 3: Schematic diagram of cytokinin functions in different stages of leaf development.
From: The diverse roles of cytokinins in regulating leaf development
The gray dashed lines divide the three stages of leaf development; the bright green area represents cells in the proliferation stage; the green area represents cells in the expansion stage; and the yellow-green area represents the senescence stage. The terms inside the red rounded rectangles are biological functions; the genes in the blue box are involved in chlorophyll synthesis. The solid arrows and blocked bars indicate activation and suppression, respectively
