Transcriptional identification of differentially expressed genes associated with division of labour in Apis cerana cerana
(0) Workers of Apis cerana cerana undergo an in-hive nursing to outdoor foraging transition,but the genes underlying this aged-related transition remain largely unknown.Here,we sequenced the head transcriptomes of its 7-day-old normal nurses,18-and 22-day-old normal foragers,7-day-old precocious foragers and 22-day-old over-aged nurses to unravel the genes associated with this transition.Mapping of the sequence reads to Apis mellifera genome showed that the 3 types of foragers had a greater percentage of reads from annotated exons and intergenic regions,whereas the 2 types of nurses had a greater percentage of reads from introns.Pair-and group-wise comparisons of the 5 transcriptomes revealed 59 uniquely expressed genes(18 in nurse and 41 in forager)and 14 nurse-and 15 forager-upregulated genes.The uniquely expressed genes are usually low-abundance lncRNAs,transcription factors,transcription coactivators,RNA-binding proteins,kinases or phosphatases that are involved in signaling and/or regulation,whereas the nurse-or forager-upregulated genes are often high-abundance downstream genes that directly perform the tasks of nurses or foragers.Taken together,these results suggest that the nurse-forager transition is coordinated by a social signal-triggered epigenetic shift from introns to exons/intergenic regions and the resulted transcriptional shift between the nurse-and forager-associated genes.
