The paper analyzes sweet potato-infecting begomoviruses and finds that genome-sequence identity thresholds fail to produce monophyletic species due to recombination and paraphyly.

This study shows that RNA phage phi6 specialists can re-expand their host ranges through mutations, including reversion of narrowing mutations or parallel mutations, indicating no constraint from their mutational backgrounds.

The paper analyzes 3D structural changes in SARS-CoV-2 proteins during the first six months of the pandemic, showing amino acid substitutions primarily affect surfaces and boundary layers.
