Fig. 4From: Identification of candidate transmission-blocking antigen genes in Theileria annulata and related vector-borne apicomplexan parasitesDiversifying selection and B cell epitopes in candidate genes. dN/dS computed from allelic sequences of (a) TA17050; (b) TA10955; (c) TA03640 and (d) TA20855, plotted against predicted B cell epitope regions (>1 amino acid, shaded areas) from GeneDB reference sequences for each protein. Epitopes with evidence of positive selection (peaks above 0) are shaded yellow, epitopes with no evidence of positive selection are shaded grey. For TA20855 and TA10955, but not TA17050 or TA03640, there was a statistically significant association between predicted epitopes and positive dN/dS, reflected in the figure by more yellow shaded areas, relative to grey Back to article page
