Extended Data Fig. 3: Mirusviricota introns.

Top left panel displays the length distribution of introns (n = 37703) detected in the 1,257 Mirusviricota genomes. Bottom left panel displays the metatranscriptomic coverage (Tara Oceans) and occurrence of introns among genes of a highly abundant marine mirusvirus. Boxplots in the right panel display the intron density (number of introns per megabase pair) of genomes organized by putative family of Mirusviricota. All individual values are displayed.
