Codon usage pattern and prediction of gene expression level in Bungarus species

Area of Science:

• Evolutionary Biology
• Molecular Biology
• Genomics

Background:

• Codon bias is crucial for understanding gene expression evolution and functional conservation.
• The genus Bungarus provides a model for comparative codon usage analysis.

Purpose of the Study:

• To compare codon usage patterns across four Bungarus species.
• To investigate factors influencing codon bias in these species.

Main Methods:

• Analysis of codon bias parameters across coding sequences.
• Correspondence analysis to assess influencing factors.
• Neutrality plot analysis to differentiate selection and mutation pressures.

Main Results:

• Low codon bias observed in the coding sequences of Bungarus species.
• Compositional constraints and gene expression levels potentially influence codon usage.
• Correspondence analysis indicated both natural selection and mutation pressure affect codon usage.

Conclusions:

• Natural selection plays a more significant role than mutation pressure in shaping codon usage patterns in Bungarus species.
• Codon usage patterns are influenced by a combination of factors including compositional constraints and gene expression levels.
