Leaf edge development (taking Arabidopsis leaf as an example). During leaf margin development, miRNA164 and CUC2 are expressed in the overlapping regions of serrated sagging, CUC2 promotes the establishment of PIN1 convergence points, and PIN1 convergence points produce the maximum value of auxin along the serrated tip of leaf margin. Auxin maximously inhibits CUC2 at the tip of the tooth and promotes the growth of the tooth (Barkoulas et al., 2007; Wang et al., 2021a).
