Key Findings
- The study from Sangmyung University focused on how water flea Daphnia galeata adapts to predation stress using alternative splicing
- Alternative splicing allows Daphnia to produce different protein variants from the same gene, enabling flexible and rapid responses to environmental changes
- The two Daphnia genotypes (KB1 and KE2) showed different patterns of alternative splicing and gene expression, indicating that genetic background influences their defensive strategies
