This study compares genome evolution in two stingless bee species, showing retroelement expansions drive heterochromatin differences and chromosomal rearrangements.

The paper examines how social tasks and aggressiveness influence immunity gene expression in the heads of stingless bees, finding upregulation in aggressive species.

The paper examines DNA methylation patterns in honey bees under different social contexts and finds no significant differences in methylomes between queenright and queenless colonies, suggesting DNA methylation is not a driver of gene expression reprogramming.

This study shows that queen pheromone upregulates epigenetic modifier genes in honeybee worker brains, suggesting pheromones influence gene expression via epigenetic mechanisms.
