Selection on Codon Bias

Annual Review of Genetics, 2008
In a wide variety of organisms, synonymous codons are used with different frequencies, a phenomenon known as codon bias. Population genetic studies have shown that synonymous sites are under weak selection and that codon bias is maintained by a balance between selection, mutation, and genetic drift.

Codon Usage Bias: An Endless Tale

Journal of Molecular Evolution, 2021
Since the genetic code is degenerate, several codons are translated to the same amino acid. Although these triplets were historically considered to be "synonymous" and therefore expected to be used at rather equal frequencies in all genomes, we now know that this is not the case. Indeed, since several coding sequences were obtained in the late '70s and

Codon bias from minimization of codon–anticodon interaction

Biosystems, 2016
Inequalities between codon usage probabilities for quartets of codons are derived using a minimum principle for codon-anticodon interaction and a probability sum rule in the framework of the Crystal Basis Model of the genetic code. Performing this study separately for the Early and for the Eukaryotic Genetic Code, we observe a consistency in the ...

Codon usage bias of Catharanthus roseus

China Journal of Chinese Materia Medica, 2016
This study aimed to provide guidance for the heterogenous gene expression, gene prediction and species evolution by analyzing codon usage bias of Catharanthus roseus.The codon composition and usage bias of 30 437 high-confidence coding sequences from C.roseus were analyzed and the proportion of rare codons of Escherichia coli and Saccharomyces ...
