Abstract: Leaf margin serration is one of morphological characteristics, which is controlled by various leaf margin factors. We reviewed domestic and foreign research results, introduced in detail the effect of plant hormone, CUC2(CUP SHAPED COTYLEDONE2) and MicroRNA on leaf margin serration development, summarized the expression and function of leaf margin factors, discussed the molecular mechanism and significance of leaf margin. Analysis showed that auxin and CUC2 had significant function in the leaf margin regulatory network and most leaf margin factors rely on auxin and CUC2. In the end, we proposed future research direction of leaf margin serration development and forecasted its application fields.
