    Codon optimization underpins generalist parasitism in fungi

    Thomas Badet et al.
    Codon optimization through biased synonymous substitutions is a characteristic feature of the genomes of generalist fungal parasites and is associated with the colonization of multiple hosts.

    A serine sensor for multicellularity in a bacterium

    Arvind R Subramaniam et al.
    Biofilm formation by Bacillus subtilis relies on a sensing mechanism for the amino acid serine that does not depend on a dedicated protein or RNA.

    Measurement of average decoding rates of the 61 sense codons in vivo

    Justin Gardin et al.
    The translation rates of each yeast codon have been measured in both the A and P sites of the ribosome.

    Avoidance of stochastic RNA interactions can be harnessed to control protein expression levels in bacteria and archaea

    Sinan Uğur Umu et al.
    Stochastic mRNA and non-coding RNA hybridisation has a major impact on protein expression.

    LARP4 mRNA codon-tRNA match contributes to LARP4 activity for ribosomal protein mRNA poly(A) tail length protection

    Sandy Mattijssen et al.
    The messenger RNA encoding La-related protein-4 (LARP4) contains a short region of instability whose codon clusters are sensitive to low abundance tRNAs that when elevated increase LARP4 activity for poly(A) lengthening of ribosomal protein mRNAs and other mRNAs.

    Recombination, meiotic expression and human codon usage

    Fanny Pouyet et al.
    Variation in codon usage among functional categories of human genes is not due to selection for translation efficiency, but to differences in intragenic recombination rate, linked to variation in meiotic transcription level.

    The distribution of fitness effects among synonymous mutations in a gene under directional selection

    Eleonore Lebeuf-Taylor et al.
    Synonymous mutations can have highly variable fitness effects stemming from changes in transcription, some of which contribute to adaptation.

    Codon usage biases co-evolve with transcription termination machinery to suppress premature cleavage and polyadenylation

    Zhipeng Zhou et al.
    Genetic and bioinformatic analyses uncover an unexpected role for codon usage biases in regulating gene expression at the transcriptional level by suppressing premature transcription termination.

    A novel twelve class fluctuation test reveals higher than expected mutation rates for influenza A viruses

    Matthew D Pauly et al.
    A new assay for specific mutational classes provides preciseestimates of the mutation rates and mutational bias for influenza A viruses.

    Evidence for adaptive evolution in the receptor-binding domain of seasonal coronaviruses OC43 and 229e

    Kathryn E Kistler, Trevor Bedford
    Phylogenetic and computational methods reveal that at least two seasonal coronaviruses are evolving adaptively in the region of the viral spike protein exposed to the human humoral immune system.
