Lectins constitute an abundant group of proteins that are present throughout the plant kingdom. Only recently, genome-wide screenings have unraveled the multitude of different lectin sequences within one plant species. It appears that plants employ a plurality of lectins, though relatively few lectins have already been studied and functionally characterized. Therefore, it is very likely that the full potential of lectin genes in plants is underrated. This review summarizes the knowledge of plasma membrane-bound lectins in different biological processes (such as recognition of pathogen-derived molecules and symbiosis) and illustrates the significance of soluble intracellular lectins and how they can contribute to plant signaling. Altogether, the family of plant lectins is highly complex with an enormous diversity in biochemical properties and activities.
凝集素是一类广泛存在于植物界的蛋白质。直到最近，通过全基因组筛选，人们才揭示了同一植物物种中存在的多种不同的凝集素序列。似乎植物会利用多种凝集素，尽管只有相对较少的凝集素已经被研究并具有功能特性。因此，植物中凝集素基因的全部潜力很可能被低估了。这篇综述总结了质膜结合凝集素在不同生物过程（如识别病原体衍生分子和共生）中的知识，并说明了可溶性细胞内凝集素的重要性以及它们如何有助于植物信号转导。总的来说，植物凝集素家族非常复杂，具有生化特性和活性的巨大多样性。
