植物和微生物利用糖缀合物作为结构实体、细胞过程的能量储备以及细胞识别或结合事件的组分。在这样的系统中碳水化合物的结构异质性是碳水化合物生物合成酶以各种形式重新定向糖单体的能力的结果，产生高度复杂的、线性的、分支的或分级的结构。在植物与病原微生物的相互作用过程中，微生物细胞表面聚糖、细胞壁聚糖和糖蛋白通过一系列特异性或广谱性的识别事件刺激植物免疫应答的信号级联。微生物聚糖诱导的植物免疫反应和在宿主植物聚糖结构中观察到的对抗微生物攻击的下游修饰最近引起了科学家的极大兴趣。这已经通过糖生物学领域的技术进步实现，使得可以更详细地研究微生物和相应的宿主聚糖结构的持续共同进化。在这场进化军备竞赛中出现的新聚糖类似物为我们理解植物-病原体相互作用带来了新的视角。本文综述了不同类型的聚糖及其衍生物，包括单糖，寡糖，糖蛋白和糖脂在激活经典的模式触发免疫（PTI）和免疫触发免疫（ETI）防御反应在植物中的作用。虽然主要包括聚糖在调节植物防御反应中的生物学作用，但本文综述了聚糖的结构，从而使其与糖生物学的其他领域相类似。此外，我们研究了这些分子目前如何被用来开发新的生物活性分子，作为引发剂，以刺激植物防御反应和设计环保叶面喷雾剂的模板，用于植物保护。
Plants and microbes utilize glycoconjugates as structural entities, energy reserves for cellular processes, and components of cellular recognition or binding events. The structural heterogeneity of carbohydrates in such systems is a result of the ability of the carbohydrate biosynthetic enzymes to reorient sugar monomers in a variety of forms, generating highly complex, linear, branched, or hierarchical structures. During the interaction between plants and their microbial pathogens, the microbial cell surface glycans, cell wall derived glycans, and glycoproteins stimulate the signaling cascades of plant immune responses, through a series of specific or broad spectrum recognition events. The microbial glycan-induced plant immune responses and the downstream modifications observed in host-plant glycan structures that combat the microbial attack have garnered immense interest among scientists in recent times. This has been enabled by technological advancements in the field of glycobiology, making it possible to study the ongoing co-evolution of the microbial and the corresponding host glycan structures, in greater detail. The new glycan analogs emerging in this evolutionary arms race brings about a fresh perspective to our understanding of plant–pathogen interactions. This review discusses the role of diverse classes of glycans and their derivatives including simple sugars, oligosaccharides, glycoproteins, and glycolipids in relation to the activation of classical Pattern-Triggered Immunity (PTI) and Effector-Triggered Immunity (ETI) defense responses in plants. While primarily encompassing the biological roles of glycans in modulating plant defense responses, this review categorizes glycans based on their structure, thereby enabling parallels to be drawn to other areas of glycobiology. Further, we examine how these molecules are currently being used to develop new bio-active molecules, potent as priming agents to stimulate plant defense response and as templates for designing environmentally friendly foliar sprays for plant protection.
