阿拉伯半乳聚糖蛋白（AGP）属于广泛存在于植物中的糖蛋白家族。 AGP 主要由装饰有复杂碳水化合物侧链的蛋白质主链组成，通常锚定在质膜上或分泌到细胞外。一系列令人信服的生化和遗传学证据表明，AGP 是与植物生长和发育相关的多种重要活动的令人兴奋的候选者。然而，由于AGP的多样性、AGP家族成员的功能冗余以及钝力研究工具，AGP的精确功能及其作用机制仍然难以捉摸。本文综述了目前关于AGPs的特性、分类和鉴定的知识，并对AGPs在植物繁殖和发育过程的多个阶段中的生物学功能进行了总结。此外，我们还根据以往的研究，特别深入讨论了AGP在不同生物过程中通过其对纤维素合成和沉积的影响的潜在机制。特别是，提出了五种假设模型，可以解释 AGP 参与植物细胞壁生物发生过程中的纤维素合成和沉积。 AGP 为了解植物中纤维素的合成和沉积开辟了新途径。
Arabinogalactan proteins (AGPs) belong to a family of glycoproteins that are widely present in plants. AGPs are mostly composed of a protein backbone decorated with complex carbohydrate side chains and are usually anchored to the plasma membrane or secreted extracellularly. A trickle of compelling biochemical and genetic evidence has demonstrated that AGPs make exciting candidates for a multitude of vital activities related to plant growth and development. However, because of the diversity of AGPs, functional redundancy of AGP family members, and blunt-force research tools, the precise functions of AGPs and their mechanisms of action remain elusive. In this review, we put together the current knowledge about the characteristics, classification, and identification of AGPs and make a summary of the biological functions of AGPs in multiple phases of plant reproduction and developmental processes. In addition, we especially discuss deeply the potential mechanisms for AGP action in different biological processes via their impacts on cellulose synthesis and deposition based on previous studies. Particularly, five hypothetical models that may explain the AGP involvement in cellulose synthesis and deposition during plant cell wall biogenesis are proposed. AGPs open a new avenue for understanding cellulose synthesis and deposition in plants.
