Gene Ontology (GO) analysis showing the correlation between GO categories and microarray expression data calculated using ErmineJ software. The GO annotations with parent-child analysis are presented on the left. Contributions to each of the categories from each lifecycle stage (2-fold or higher gene expression) are shaded. The overall number of genes in each category represented on the microarray and the correlation p-value associated with the entire lifecycle are shown on the right. NA, the parent category is significant but a child category is not. Genes expressed in adult parasites from weeks 6–7.
