Ecological Adaptation of Diverse Honey Bee (*Apis mellifera*) Populations.
PLoS ONE 5(6): e11096. doi:10.1371/journal.pone.0011096

The primary objective of this study was to determine the diversity of
protein expression in commercial honey bee populations, to develop an
understanding of the mechanisms used by bee populations to adapt to
different agro-ecological conditions and to develop tools for bee breeders.
Our approach towards this objective was to test the null hypothesis that no
differences in expression exist among the populations, given that queen
production is centralized in a few locations. In order to address these
goals, we carried out a quantitative analysis of the midgut proteome from
adult nurse bees. The adult worker midgut was chosen as it is a key organ in
a bee's interaction with its environment: it is the primary site of
processing for ingested nutrients and toxins, and as the route of entry for
enteric pathogens, the midgut is also involved in individual

and

resistance
to disease. The honey bee gut was also the organ of choice in a recent gene
expression study investigating the cause of Colony Collapse Disorder (CCD)

Interestingly, alongside potential markers associated with the prevalence of
CCD, the geographical origin of the colonies was shown to affect gene
expression. The bees used in our study were all reared and sampled at the
Alberta-based Beaverlodge Research Farm from queens imported from diverse
geographical locations, including eastern and central Canada, California,
Hawaii, Chile and New Zealand. Our findings unveil major differences in the
basic biochemical machinery of these bees, especially proteins involved in
metabolism, protein processing and translation. These results have major
implications for apiculture as they provide a molecular explanation for the
common observation that transplanted bees from different climates cannot
always adjust well to a new location
