Comparative brain transcriptomic analyses of scouting across distinct behavioural and ecological contexts in honeybees.

摘要: Individual differences in behaviour are often consistent across time and contexts, but it is not clear whether such consistency reflected at the molecular level. We explored this issue by studying scouting honeybees two different behavioural ecological contexts: finding new sources of floral food resources a nest site. Brain gene expression profiles food-source nest-site scouts showed significant overlap, despite large associated with contexts. Class prediction ‘leave-one-out’ cross-validation analyses revealed that bee's role as scout either context could be predicted 92.5% success using 89 genes minimum. also found related to four neurotransmitter systems were part shared brain signature both types scouts, more similar for glutamate GABA than catecholamine or acetylcholine signalling. These results indicate tendencies contexts involve mixture similarities expression.
