Story summary

Virginia Tech researchers identified a giant virus, punuivirus, in the green alga Chlamydomonas reinhardtii, challenging existing virus size concepts.
The 617-kilobase genome can integrate into host DNA, enabling dormancy and reactivation without host damage.
This discovery could impact gene editing methods and enhance understanding of microbial evolution and ecosystem dynamics.
