Phylogenetic tree (ML) of dereplicated (97%) 16S rRNA gene sequences from Ca. Patescibacteria retrieved from NCBI genome collection (January 2022) and freshwater datasets. MAGs coming from from Baikal 1250 m, 1350 m (Illumina) and 1600 m (PacBio CCS) are blue coloured. 16S RNA genes obtained from single reads from PacBio CCS from the 1600 m sample are purple coloured. Taxonomic classification based on the Genome Taxonomy Database (GTDB) is shown: inner circle—class, outer circle—family. The Baikalibacteria are highlighted in red
