Enhancing the genetic transformation efficiency of major crops remains a significant challenge, primarily due to their suboptimal regeneration efficiency. Developmental regulators, known as key regulatory genes, involved in plant meristem and somatic embryo formation, play a crucial role in improving plant meristem induction and regeneration. This review provides a detailed summary of the molecular mechanisms and regulatory networks of many developmental regulators, in the context of enhancing the genetic transformation efficiency in major crops. We also propose strategies for exploring and utilizing additional developmental regulators. Further investigation into the mechanisms of these regulators will deepen our understanding of the regenerative capacity and genetic transformation processes of plants, offering valuable support for future crop improvement efforts. The discovery of novel developmental regulators is expected to further advance crop transformation and the effective manipulation of various developmental regulators could provide a promising approach in order to enhance genetic transformation efficiency.
提高主要作物的遗传转化效率仍然是一项重大挑战，主要原因是它们的再生效率不理想。发育调控因子，即参与植物分生组织和体细胞胚胎形成的关键调控基因，在提高植物分生组织诱导和再生方面起着至关重要的作用。本综述详细总结了许多发育调控因子在提高主要作物遗传转化效率背景下的分子机制和调控网络。我们还提出了探索和利用其他发育调控因子的策略。对这些调控因子机制的进一步研究将加深我们对植物再生能力和遗传转化过程的理解，为未来的作物改良工作提供有价值的支持。预计新型发育调控因子的发现将进一步推动作物转化，有效操纵各种发育调控因子可能为提高遗传转化效率提供一种有前景的方法。
