Extended Data Fig. 4: Global distribution of “Ca. Kariarchaeum pelagium” and patterns of variation across its genome.
From: Structural insights into light harvesting by antenna-containing rhodopsins in marine Asgard archaea
a, Distribution of “Ca. K. pelagium” based on Logan contigs from marine metagenomes and metatranscriptomes recruited to the “Ca. K. pelagium” core pan-genome. Abundances are expressed as fractions of the pan-genome covered by the mapped contigs with a minimum coverage of 0.5%. Locations of “Ca. K. pelagium” MAGs are indicated with labels coloured according to the heimdallR allele type. Locations of the other “Ca. Kariarchaeum” are indicated for reference: MAG FT_008 (sp016839545) and scaffold Kari_Gs0128817 (sp. nov.). b, Per-nucleotide depth of coverage of Logan metagenomic contigs along the core pan-genome of “Ca. K. pelagium” (upper) and number of variable positions per nucleotide for genes across the pan-genome. Only genes with ORF longer than 300 bp were analyzed. Asterisks indicate outlier genes with values exceeding upper quartile + 1.5×interquartile range. c, Number of variable positions per nucleotide for sliding windows of 200 bp across the pan-genomic scaffold containing the heimdallR gene (scaffold 11). In panels b and c, upper and lower quartiles (dashed lines) and median (solid lines) are indicated.
