4. Conclusion
Here, a high-quality chromosome-level genome assembly of C. striatipennis with genome size of 181.84Mb and 13429 annotated protein-coding genes has been reported. Through phylogenetic analysis, the possible position of C. striatipennis in evolutionary relationship was clarified. By the analysis of expanded gene family, their possible role (such as hemoglobin, GST, CYP450s, JHAMT, etc.) in the adaptability of benthic environment were clarified. In addition, in the process of metamorphosis, C. striatipennis depends more on JNK signal pathway to initiate the apoptosis pathway, and then smoothly complete the eclosion process. The results in this research provide a relatively high-quality genome and a foundation for revealing the evolutionary direction of organisms in adverse environments.
