Morphogenetic factors (MTFs) are specialized plant genes and transcription factors that play pivotal roles in embryogenesis and organogenesis. This review focuses on their functions in plant development regulation and their applications in plant biotechnology and modern breeding. Common challenges in transformation and regeneration were discussed, along with successful case studies demonstrating improved regeneration capacity and transgene stability in rice (), soybean (), rapeseed (), tomato () and other less common crops and plant model organisms. These improvements were achieved through the utilization of key developmental MTFs such as , , , etc. The principles of designing genetic constructs with MTFs are explored, including promoter selection and regulatory elements, as well as their synergistic effects with phytohormones like auxins and cytokinins for optimizing in vitro morphogenesis. Current limitations in MTF expression and strategies to overcome them are analyzed. The article highlights recent advances, including MTFs potential for developing stress-resistant, high-yielding cultivars. Key discussion points include the discovery of novel morphogens, their application to recalcitrant species, and prospects for expanding the range of easily transformable and regenerable crops. Future directions involve developing universal transformation protocols and integrating morphogens with precision genome editing technologies, offering new opportunities for agriculture and global food security.
形态发生因子(MTFs)是一类特殊的植物基因和转录因子,在胚胎发生和器官发生过程中发挥着关键作用。本综述聚焦于它们在植物发育调控中的功能,以及在植物生物技术和现代育种中的应用。文中讨论了转化和再生过程中常见的挑战,并列举了成功案例研究,展示了水稻()、大豆()、油菜籽()、番茄()以及其他不太常见的作物和植物模式生物在再生能力和转基因稳定性方面的提升。这些提升是通过利用关键的发育性MTFs实现的,如、、等。探讨了利用MTFs设计遗传构建体的原则,包括启动子选择和调控元件,以及它们与生长素和细胞分裂素等植物激素的协同作用,以优化体外形态发生。分析了MTF表达目前存在的局限性以及克服这些局限性的策略。文章强调了近期的进展,包括MTFs在培育抗逆、高产作物品种方面的潜力。关键讨论点包括新型形态发生素的发现、它们在难转化物种中的应用,以及扩大易于转化和再生作物范围的前景。未来的方向包括开发通用的转化方案,以及将形态发生素与精确基因组编辑技术相结合,为农业和全球粮食安全带来新机遇。
