Table 3 Overlap of genes regulated in the abdomen by pollen feeding or varroa parasitism

From: Nutrigenomics in honey bees: digital gene expression analysis of pollen's nutritive effects on healthy and varroa-parasitized bees

1)   Varroa -   2) Pollen -   
   Pollen ↑ Pollen ↓ Significance    Varroa ↑ Varroa ↓ Significance
Varroa + Pollen ↑ 111 8 χ2 = 190.1 Pollen + Varroa ↑ 8 7 χ2 = 74.6
  Pollen ↓ 244 624 P < 0.001   Varroa ↓ 81 1925 P < 0.001
  1. 1) Number of genes regulated by pollen feeding in bees parasitized (Varroa +) or not by varroa (Varroa -). 2) Number of genes regulated by varroa parasitism in bees fed with (Pollen +) or without pollen (Pollen -). ↑ and ↓ indicate genes that are up- or downregulated. Chi-square tests with Yates correction were performed to determine whether overlapping genes follow the same pattern of expression between the two conditions.
