Pseudogenization of rcsD alters canonical Rcs phosphorelay signalling and marks a significant adaptive evolutionary step in the emergence of ubiquitous extant branches of Yersinia pestis that can maintain stable plague outbreaks.

Combining ribosome profiling and RNA sequencing illuminates novel features of porcine reproductive and respiratory syndrome virus gene expression, including the regulation of polyprotein stoichiometry through temporal modulation of ribosomal frameshifting and the synthesis of non-canonical transcripts.

Genetic and biochemical analyses reveal an important role for the translesion DNA polymerase DinB2 in mycobacterial mutagenesis, including in the insertion/deletion events that are an increasingly recognized type of diversity in Mycobacterium tuberculosis genomes.

Chemical modifications near the tRNA anticodon and specific mRNA–tRNA pairs combine to control the ribosomal three-nucleotide mRNA reading frame, essential for the sequential addition of amino acids into polypeptide chains.

An eukaryotic specific system cooperates with the ribosome quality control pathway to maintain the reading frame during translation of slowly translated sequences.

By sterically hindering tRNA binding and inhibiting translation elongation, mRNA stem-loops can modulate gene expression.

The efficiency with which ribosomes shift reading frames when decoding viral RNA may change over the course of an infection.

Cells resolve unassigned codons with near-cognate suppression, frameshifting, and ribosomal rescue mechanisms, demonstrating that unassigned codons are permissible in both natural and engineered genetic codes as barriers to horizontal gene transfer.

In the fungal pathogen Cryptococcus neoformans, the RAM pathway, potentially through post-transcriptional regulation, plays an essential role in adaptation to host temperature and CO₂.

CRISPR/Cas knockout of intraflagellar transport protein 80 shows that this subunit is absolutely required for ciliogenesis, and biophysical studies reveal that this protein may dimerize the intraflagellar transport complex.
