Parent of origin gene expression in the bumblebee, Bombus terrestris, supports Haig’s kinship theory for the evolution of genomic imprinting

Abstract: Genomic imprinting is the differential expression of alleles in diploid individuals, with the expression being dependent upon the sex of the parent from which it was inherited. Haig’s kinship theory hypothesizes that genomic imprinting is due to an evolutionary conflict of interest between alleles from the mother and father. In social insects, it has been suggested that genomic imprinting should be widespread. One recent study identified parent-of-origin expression in honeybees and found evidence supporting th… Show more

“…Finally, genes showing PSGE were also in modules enriched in genes involved in post‐transcriptional processing, suggesting that they may influence physiology and behaviour through these pathways. As genomic resources expand and methods for manipulating gene expression and gene sequences become more sophisticated, it will be important to evaluate these mechanisms in other bee species (Grozinger & Zayed, 2020), particularly those where the predictions of patrigene vs. matrigene expression bias in mediating worker reproduction may differ (see Marshall, van Zweden, et al, 2020).…”

“…We analyzed previously published RNA-seq data from ant species with fixed queen-worker (Solenopsis invicta and Monomorium pharaonis) or queenless social systems (Dinoponera quadriceps and Ooceraea biroi). We also analyzed two species of wasps (Polistes dominula and Polistes canadensis) and bees (Bombus terrestris and Megalopta genalis) (Chandra et al, 2018;Kapheim et al, 2020;Marshall et al, 2020;Patalano et al, 2015;Standage et al, 2016;Wang et al, 2020). In all cases, genes differentially expressed between non-reproductive and reproductive individuals overlapped significantly with genes regulated by JH3 and 20E in Harpegnathos neuronal cultures (Figure S3, Venn diagrams).…”
