Expression patterns of 5-HT receptor genes in the crop and the midgut of adult forager honeybees determined by quantitative real-time PCR (N = 5/ tissue). Transcript levels were normalized to Amef-1α as a reference gene. Significant post hoc comparisons in expression of each receptor mRNA within each tissue (crop or midgut) are indicated with by letters (capital letters = crop; lower-case = midgut). Significant post hoc comparisons for the expression of each receptor in the crop and midgut are indicated by asterisks (indicated as P < 0.05; ∗∗∗P < 0.001).
