The reconstructed genomes of novel Ca. Nanohaloarchaeota. a Relative abundance of the major microbial groups in eight layers of a stratified salt crust and underlying water based on amplicon sequencing of the 16S rRNA gene. b Relative abundances of the three Ca. Nanohaloarchaeota MAGs recovered from the present study. c Phylogenetic placements of the novel Ca. Nanohaloarchaeota MAGs. The tree was constructed based on the concatenated alignment of 16 ribosomal proteins using IQ-TREE with the best model of LG + F + R9. Bootstrap values were based on 1000 replicates, and nodes with confidence > 70% are indicated as black circles
