Woesearchaeota is a newly proposed archaeal phylum frequently detected in various environments. Due to the limited systematical study, little is known about their distribution, taxonomy, and metabolism. Here, we conducted a comprehensive study for Woesearchaeota with 16S ribosomal RNA (rRNA) gene sequencing data of 27,709 samples and metagenomic whole genome sequencing (WGS) data of 1,266 samples. We find that apart from free-living environments, Woesearchaeota also widely distribute in host-associated environments. And host-associated environmental parameters greatly affect their distribution. 81 Woesearchaeota genomes, including 33 genomes firstly reconstructed in this project, were assigned to 59 Woesearchaeota species, suggesting their high taxonomic diversity. Comparative analysis indicated that Woesearchaeota have an open pan-genome with small core genome. Metabolic reconstruction showed that particular metabolic pathway absence in specific environments, demonstrated the metabolic diversity of Woesearchaeota varies in differences environments. These results have placed host-associated environments into the global biogeography of Woesearchaeota and have demonstrated their genomic diversity for future investigation of adaptive evolution.
