This study establishes a Chikungunya virus pseudotype system using envelope proteins from different viral families, showing compatibility with receptors and no false-positive infections.

The paper identifies and characterizes env-ORFs in monotreme genomes, showing that fusogenic retroviral genes exist in egg-laying mammals, not just placental ones.

The paper identifies three monotreme-specific reverse transcriptase-like genes derived from ERVs in platypus and echidna genomes, showing their conservation and testis-specific expression.

The paper identifies a conserved retroviral RNA element, SPRE, present in multiple ERV-derived genes across mammals and shows its role in enhancing protein expression.
