Photosynthesis, the ability to fix atmospheric carbon dioxide, was acquired by eukaryotes through symbiosis: the plastids of plants and algae resulted from a cyanobacterial symbiosis that commenced more than 1.5 billion years ago and has chartered a unique evolutionary path. This resulted in the evolutionary origin of plants and algae. Some extant land plants have recruited additional biochemical aid from symbiotic cyanobacteria; these plants associate with filamentous cyanobacteria that fix atmospheric nitrogen. Examples of such interactions can be found in select species from across all major lineages of land plants. The recent rise in genomic and transcriptomic data has provided new insights into the molecular foundation of these interactions. Furthermore, the hornwort has emerged as a model system for the molecular biology of cyanobacteria-plant interactions. Here, we review these developments driven by high-throughput data and pinpoint their power to yield general patterns across these diverse symbioses.
光合作用，即固定大气中二氧化碳的能力，是真核生物通过共生获得的：植物和藻类的质体源于15亿多年前开始的蓝细菌共生，并走上了独特的进化道路。这导致了植物和藻类的进化起源。一些现存的陆地植物从共生蓝细菌那里获得了额外的生化帮助；这些植物与能固定大气氮的丝状蓝细菌相关联。在陆地植物所有主要谱系的特定物种中都能找到这种相互作用的例子。最近基因组和转录组数据的增加为这些相互作用的分子基础提供了新的见解。此外，金鱼藻已成为研究蓝细菌与植物相互作用分子生物学的模式系统。在这里，我们回顾由高通量数据推动的这些进展，并指出它们揭示这些不同共生关系中普遍模式的能力。
