摘要
叶缘锯齿是叶片重要的形态特征之一,受到多种叶缘发育因子的调控。笔者回顾了国内外研究成果,详细分析了植物激素、CUC2(CUP SHAPED COTYLEDONE2)和MicroRNA对叶缘锯齿发育的影响,总结了植物中各叶缘因子的表达与功能,并探讨了叶缘锯齿形成的分子机制及其意义。分析表明,在复杂的叶缘发育调控网络中,生长素与CUC2对叶缘的调控起到非常重要的作用,大部分叶缘因子的调控功能依赖于生长素和CUC2。最后,展望了叶缘锯齿发育未来的研究方向与发展趋势,并对其以后的应用领域进行了预测。
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 planthormone, CUC2(CUP SHAPED COTYLEDONE2) and MicroRNA on leaf margin serration development,summarized the expression and function of leaf margin factors, discussed the molecular mechanism andsignificance of leaf margin. Analysis showed that auxin and CUC2 had significant function in the leaf marginregulatory network and most leaf margin factors rely on auxin and CUC2. In the end, we proposed futureresearch direction of leaf margin serration development and forecasted its application fields.
