Transcriptome Analysis of the NematodeCaenorhabditis elegansin Acidic Stress Environments
Ocean acidification and acid rain, caused by modern industries' fossil fuel burning, lead to a decrease in the living environmental pH, which results in a series of negative effects on many organisms. However, the underlying mechanisms of animals' response to acidic pH stress are largely u...
