Abstract

Cutting propagation is a commonly employed technology for vegetative reproduction in agricultural, forestry, and horticultural practice. The success of cutting propagation depends on adventitious root (AR) formation-a process whereby roots regenerate from stem cuttings or leaf cuttings. In this review, we summarize the distinct stages of cutting-induced AR formation and highlight the pivotal roles of plant hormones and age in this process. Jasmonic acid (JA) acts as a master trigger for promoting AR formation, while auxin serves as the core regulator, driving AR formation. Furthermore, plant age is a crucial factor determining the regenerative competence of cuttings. Notably, age and JA collaboratively modulate auxin synthesis in cutting-induced AR formation. Overall, this review not only elucidates the molecular mechanisms underlying AR formation but also provides valuable insights for improving efficiency of cutting propagation in various plant species.

摘要

扦插繁殖是农业、林业和园艺实践中常用的营养繁殖技术。扦插繁殖的成功取决于不定根（AR）的形成，即从茎插条或叶插条再生根的过程。在这篇综述中，我们总结了扦插诱导不定根形成的不同阶段，并强调了植物激素和年龄在这一过程中的关键作用。茉莉酸（JA）作为促进不定根形成的主要触发因素，而生长素则作为核心调节因子，驱动不定根的形成。此外，植株年龄是决定插条再生能力的关键因素。值得注意的是，年龄和茉莉酸在扦插诱导不定根形成过程中协同调节生长素的合成。总的来说，这篇综述不仅阐明了不定根形成的分子机制，还为提高各种植物物种扦插繁殖的效率提供了有价值的见解。
