Positive selection analysis of Cyt proteins from Bacillus thuringiensis: A conservative trend driven by negative (purifying) selection

Key Points

• Cyt proteins exhibit a conservative trend driven by purifying selection, emphasizing their evolutionary roles.
• The analysis indicates that this negative selection maintains important functions within Bacillus thuringiensis.
• Assessment involved molecular evolutionary analyses of Cyt proteins to highlight selection dynamics.
• Findings suggest implications for understanding how Bacillus thuringiensis adapts and maintains its fitness in diverse environments.
