The crystal structure of a Polerovirus exoribonuclease-resistant RNA shows how diverse sequences are integrated into a conserved fold

A.-L. Steckelberg, Q. Vicens, D. A. Costantino, J. C. Nix, J. S. Kieft

The paper presents the crystal structure of a polerovirus xrRNA, revealing sequence diversity within a conserved fold and explaining conservation patterns and new interactions.

A folded viral noncoding RNA blocks host cell exoribonucleases through programmed remodeling of RNA structure

A.-L. Steckelberg, B. M. Akiyama, D. A. Costantino, T. L. Sit, J. C. Nix, J. S. Kieft

The paper identifies a novel RNA structure-dependent mechanism in dianthoviruses that blocks exoribonucleases, revealing convergent evolution of xrRNAs across unrelated viral families.
