Abstract:
Studies on the expression of genes in different contexts are essential to
our understanding of the functioning of organisms and their adaptations to
the environment. Gene expression studies require steps of normalization,
which are done using the stable expression pattern of reference genes. For
many different eusocial bees reference genes have been discovered, but
not for the primitively eusocial Euglossini bees. We used available genomic
resources of Euglossini species and the gene information of Apis mellifera
Linnaeus to develop a set of reference genes for the primitive eusocial bee
Euglossa viridissima Friese. We tested nine genes, in distinct developmental
stages, using three different algorithms, to infer stability of gene expression.
The TATA-binding protein (TBP) and 14-3-3 epsilon were the most stable
genes across all developmental stages. The strongest deviation in gene
expression pattern occurred in pupae, which require a different set of genes
for normalizing gene expression.
