This study shows that spherical mreB deletion mutants of Pseudomonas fluorescens SBW25 can regain fitness through mutations in Pbp1A, restoring cell size homeostasis and supporting a hypothesis about balanced transpeptidase and glycosyltransferase functions.

The paper sequences 320 SARS-CoV-2 genomes from Houston to study early pandemic spread, finding diverse origins and no evidence of more virulent strains.
