Xylan is a vital component of plant cell walls, contributing to their structural integrity and flexibility through interactions with other polymers. Its structure varies among plant species, influencing the mechanical properties of cell walls. Xylan also has significant industrial potential, including in biofuels, biomaterials, food, and pharmaceuticals, due to its ability to be converted into valuable bioproducts. However, key aspects of xylan biosynthesis, regulation, and structural impact on plant growth and structures remain unclear. This review highlights current researches on xylan biosynthesis, modification, and applications, identifying critical gaps in knowledge. Meanwhile the review proposes new approaches to regulate xylan synthesis and understand its role in cell wall assembly and interactions with other polymers. Addressing these gaps could unlock the full industrial potential of xylan, leading to more sustainable applications.
木聚糖是植物细胞壁的重要组成部分，通过与其他聚合物相互作用，有助于维持细胞壁的结构完整性和柔韧性。其结构因植物种类而异，影响着细胞壁的机械性能。由于木聚糖能够转化为有价值的生物产品，它在生物燃料、生物材料、食品和制药等领域也具有巨大的工业潜力。然而，木聚糖生物合成、调控及其对植物生长和结构的结构影响等关键方面仍不清楚。本综述重点介绍了目前关于木聚糖生物合成、修饰和应用的研究，找出了知识上的关键空白。同时，该综述提出了调控木聚糖合成以及理解其在细胞壁组装和与其他聚合物相互作用中作用的新方法。填补这些空白可能会释放木聚糖的全部工业潜力，带来更可持续的应用。
