Analysis of codon usage bias of mitochondrial genome in Bombyx mori and its relation to evolution.

ABSTRACT:

Background

Synonymous codon usage bias (SCUB) is an inevitable phenomenon in organismic taxa, generally referring to differences in the occurrence frequency of codons across different species or within the genome of the same species. SCUB happens in various degrees under pressure from nature selection, mutation bias and other factors in different ways. It also attaches great significance to gene expression and species evolution, however, a systematic investigation towards the codon usage in Bombyx mori (B. mori) has not been reported yet. Moreover, it is still indistinct about the reasons contributing to the bias or the relationship between the bias and the evolution of B. mori.

Results

The comparison of the codon usage pattern between the genomic DNA (gDNA) and the mitochon
