Compare Analysis of Codon Usage Bias of Nuclear Genome in Eight Sapindaceae Species.

ABSTRACT: Codon usage bias (CUB) refers to the different frequencies with which various codons are utilized within a genome. Examining CUB is essential for understanding genome structure, function, and evolution. However, little was known about codon usage patterns and the factors influencing the nuclear genomes of eight ecologically significant Sapindaceae species widely utilized for food and medicine. In this study, an analysis of nucleotide composition revealed a higher A/T content and showed a preference for A/T at the third codon position in the eight species of Sapindaceae. A correspondence analysis of relative synonymous codon usage explained only part of the variation, suggesting that not only natural selection but also various other factors contribute to selective constraints on codon bias
