Analysis of antennal transcriptome and gustatory receptor genes in Apis cerana cerana collecting pollens from different nectar source plants.

ABSTRACT: Taste perception is crucial for guiding food selection and regulating insect feeding behaviors. This study aimed to identify taste-related genes in Apis cerana cerana by analyzing antennal transcriptomes through RNA sequencing and functional annotation. Results showed 241, 135, and 102 differentially expressed genes (DEGs) in the YC (rapeseed pollen foragers) vs. CC (non-foraging controls), LC (pear pollen foragers) vs. CC, and LC vs. YC groups, respectively. GO annotation indicated these DEGs were enriched in functions like defense response to Gram-positive bacteria, integral component of plasma membrane, and signal transduction. KEGG analysis revealed involvement in pathways such as tyrosine metabolism and neuroactive ligand-receptor interaction. Five gustatory receptor genes were identi
