Area of Science:

* Insect genetics and developmental biology.
* Conservation genomics and transcriptomics.

Background:

* Parnassius bremeri (Snow Apollo butterfly) is an endangered species with limited genomic resources.
* Understanding its developmental gene expression is vital for conservation efforts.

Purpose of the Study:

* To identify differentially expressed genes (DEGs) across metamorphic stages of Parnassius bremeri.
* To elucidate the molecular mechanisms underlying its development and inform conservation strategies.

Main Methods:

* High-throughput transcriptome sequencing was employed to analyze gene expression.
* Differential gene expression analysis identified 72,161 DEGs across eight comparisons.

Main Results:

* DEGs were linked to cuticle development and melanin biosynthesis during larval stages.
* Key signaling pathways (Wnt, Hedgehog, Notch) and sensory receptors were regulated during development, particularly the larval-to-adult transition.

Conclusions:

* This research provides foundational transcriptomic data for Parnassius bremeri.
* Identified genes and pathways offer insights into metamorphic development crucial for conservation strategies.
