The paper surveys sporulation genes in Paenibacillus genomes, finding a conserved phosphorelay but a unique transmembrane-domain-containing Spo0B variant present in 92% of species.

The paper analyzes >12,000 bacterial genomes to study the conservation and evolution of the programmed ribosomal frameshift in prfB, finding it was present in the last common ancestor of bacteria and linked to stop codon usage.

This study identifies YebC2 as a translation factor that resolves ribosome stalling at polyprolines independently of EF-P and YfmR in B. subtilis.
