Full-Length Transcriptome Profile of Apis cerana Revealed by Nanopore Sequencing

Area of Science:

• Genomics and Transcriptomics
• Entomology
• Apiculture

Background:

• The Asian honey bee (Apis cerana) is vital for ecosystems and honey production.
• Existing genomic data for Apis cerana is incomplete, particularly transcriptomic information.
• Understanding the transcriptome is essential for exploring gene function and regulation.

Purpose of the Study:

• To construct and analyze full-length transcriptomes from queen, drone, and worker Apis cerana.
• To identify novel transcripts, alternative splicing, alternative polyadenylation, SSRs, and lncRNAs.
• To provide a comprehensive transcriptomic dataset for Apis cerana research.

Main Methods:

• Pooled RNA samples from queen, drone, and worker Apis cerana.
• Full-length RNA sequencing utilizing Nanopore single-molecule sequencing technology.
• Bioinformatic analysis to identify transcripts, gene expression, AS, APA, SSRs, and lncRNAs.

Main Results:

• Generated 160,811 full-length transcript sequences from 19,859 genes, including 141,189 novel transcripts.
• Identified tissue-specific transcripts, 38,799 alternative splicing events, 44,243 APA sites, 88,187 SSRs, and 17,387 lncRNAs.
• Detected differentially expressed transcripts between reproductive and worker tissues.

Conclusions:

• This study provides the most comprehensive transcriptomic dataset for Apis cerana to date.
• The generated data offers valuable sequence information for future functional genomics studies.
• The findings enhance our understanding of Apis cerana gene expression and regulation.
