Land plants (embryophytes), including vascular (tracheophytes) and non-vascular plants (bryophytes), co-evolved with microorganisms since descendants of an algal ancestor colonized terrestrial habitats around 500 million years ago. To cope with microbial pathogen infections, embryophytes evolved a complex immune system for pathogen perception and activation of defenses. With the growing number of sequenced genomes and transcriptome datasets from algae, bryophytes, tracheophytes, and available plant models, comparative analyses are increasing our understanding of the evolution of molecular mechanisms underpinning immune responses in different plant lineages. In this review, recent progress on plant immunity networks is highlighted with emphasis on the identification of key components that shaped immunity against pathogens in bryophytes compared to angiosperms during plant evolution.
陆地植物(胚胎植物),包括维管植物(有导管植物)和非维管植物(苔藓植物),自大约 5 亿年前藻类祖先的后代殖民到陆地栖息地以来,与微生物共同进化。为了应对微生物病原体的感染,胚胎植物进化出了一种复杂的免疫系统,用于感知病原体并激活防御。随着藻类、苔藓植物、有导管植物的测序基因组和转录组数据集以及可用的植物模型的数量不断增加,比较分析正在增加我们对不同植物谱系中免疫反应的分子机制进化的理解。在这篇综述中,重点强调了植物免疫网络的最新进展,特别是在鉴定关键成分方面的进展,这些成分塑造了苔藓植物相对于被子植物在植物进化过程中对病原体的免疫反应。
