Chromosomally integrated MGEs and defense systems in soil Asgard Archaea genomes. Each panel (A–C) depicts the coverage across each complete genome, as determined by mapping to metagenome reads derived from three different soil depth profiles. Regions exhibiting low coverage suggest strain variations associated with specific soil depths and may indicate the presence of integrated MGEs in only a subset of cells. Notably, the Freyarchaeia genome exhibits even coverage using reads from all sampling depths, with no discernible integrated MGEs identified. Some of the low-coverage regions are not labeled as potential MGEs; these regions are strain variants with sequences so divergent that read mapping is precluded. Oval symbols indicate predicted defense systems.
