Developmental Transcriptome Analysis of Red-Spotted Apollo Butterfly, Parnassius bremeri.

ABSTRACT: Parnassius bremeri (P. bremeri), a member of the genus Snow Apollo in the swallowtail family (Papilionidae), is a high alpine butterfly that lives in Russia, Korea, and China. It is an endangered wildlife (Class I) in South Korea and is a globally endangered species. The lack of transcriptomic and genomic resources of P. bremeri significantly hinders the study of its population genetics and conservation. The detailed information of the developmental stage-specific gene expression patterns of P. bremeri is of great demand for its conservation. However, the molecular mechanism underlying the metamorphic development of P. bremeri is still unknown. In the present study, the differentially expressed genes (DEGs) across the metamorphic developmental stages were compared using high-throughput transcriptome sequencing. We identified a total of 72,161 DEGs from eight comparisons. GO enrichment analysis showed that a range of DEGs were responsible for cuticle development and the melanin biosynthetic pathway during larval development. Pathway analysis suggested that the signaling pathways, such as the Wnt signaling pathway, hedgehog signaling pathway and Notch signaling pathway, are regulated during the developmental stages of P. bremeri. Furthermore, sensory receptors were also activated, especially during the larval to adult transition stage. Collectively, the results of this study provide a preliminary foundation and understanding of the molecular mechanism in their transcriptomes for further research on the metamorphic development of P. bremeri.
