Venn diagram representing Rhipicephalus microplus genes regulated by feeding. The number of regulated genes is shown followed by signs which denote the direction of the regulation; the single plus (+) or minus (−) sign indicates up- or down-regulation, respectively, in all groups included in the intersection. Multiple plus (+) and minus (−) signs depict the gene expression regulation observed in the all groups included in the intersection starting from the group labelled ‘MG 2d’ to the group labelled ‘SG 9d’. MG, midgut; SG, salivary glands; d, day.
