a Photograph of the vernal pool that was sampled for metagenomics analyses in this study, in Lake County, California, USA. b Archaeal genomic abundance excluding bacterial genomes. c Phylogenetic distribution of Asgard Archaea complete genomes. The maximum-likelihood phylogeny was generated with IQ-TREE v1.6.1, utilizing 47 concatenated archaeal Clusters of Orthologous Groups of proteins (arCOGs). The best-fit model was determined as LG + F + R10 based on the Bayesian Information Criterion. Non-parametric bootstrapping was conducted with 1000 replicates for robustness. The filled-in square, circle, and triangle indicate closed complete genomes from short reads, published complete genomes from long reads, and genomes from co-isolated cultured representatives, respectively. The Pentagon highlights the long-read draft genomes from this site (PacBio or Nanopore). d Indicators of bidirectional replication in Atabeyarchaeia complete genomes. The GC skew is shown as a gray plot overlaying the cumulative GC skew, presented as a green line. The blue lines mark the predicted replication terminus. Source data are provided as a Source Data file.
