Multi-omics analysis identifies ALDH7A1 as a key regulator of the visual-olfactory bimodal learning in honeybee


ABSTRACT: Specific genes or encoded proteins are involved in regulating various learning models of different species through certain signaling pathways,but whether there are also regulatory genes during bimodal learning and memory is largely unknown. Using a multi-omics approach to examine gene expression changes in bees brain performed with three different learning assays, a general up-regulation of genes and proteins were observed in bimodal learning compared to controls. Protein-protein network predictions of differential proteins together with FISH assays suggest ALDH7A1 may be involved in regulation of bimodal learning and memory. Injecting siRNA-ALDH7A1 to the bee brain results in significant inhibition the expressions of ALDH7A1 and regucalcin, and increase β-alanine content. Interestingly, we found that loss of ALDH7A1 only affect visual-olfactory bimodal learning and memory, but not single visual or olfactory conditioned learning after ALDH7A1-RNAi in bees. Therefore, our data suggests that ALDH7A1 may affect bimodal learning and memory though controlling β-alanine related plasticity mechanisms.
