www.nature.com/articles/s41... Thrilled to share our new study! We show that mirusviruses include lineages packed with spliceosomal introns and likely replicating in the nucleus of unicellular eukaryotes—a sharp contrast to most large and giant eukaryotic viruses that replicate in the cytoplasm.
Widespread and intron-rich mirusviruses are predicted to reproduce in nuclei of unicellular eukaryotes - Nature Microbiology
Environmental metagenomic explorations show that Mirusviricota lineages lack essential replication and transcription genes and contain spliceosomal introns, suggesting nuclear reproduction.
