Lateral roots (LRs), are an important component of plant roots, playing a crucial role in anchoring the plant in the soil and facilitating the uptake of water and nutrients. As post-embryonic organs, LRs originate from the pericycle cells of the primary root, and their formation is characterized by precise regulation of cell division and complex intercellular interactions, both of which are closely tied to cell wall regulation. Considering the rapid advances in molecular techniques over the past three decades, we reframe the understanding of the dynamic change in cell wall during LR development by summarizing the factors that precipitate these changes and their effects, as well as the regulated signals involved. Additionally, we discuss current challenges in this field and propose potential solutions.
侧根是植物根系的重要组成部分，在将植物固定于土壤以及促进水分和养分吸收方面发挥着关键作用。作为胚后器官，侧根起源于主根的中柱鞘细胞，其形成的特征在于细胞分裂的精确调控和复杂的细胞间相互作用，这两者均与细胞壁调控密切相关。鉴于过去三十年分子技术的快速发展，我们通过总结促成这些变化的因素及其影响以及所涉及的调控信号，重新构建了对侧根发育过程中细胞壁动态变化的理解。此外，我们还讨论了该领域当前面临的挑战并提出了潜在的解决方案。
