The FC range at 1 dpi was 0.77–1.22; among the 12 genes, Toll-like receptor 7 (TOLL7, LOC5575353, AAEL002583) exhibited a significant increase in expression after infection (P < 0.05), with a FC of 1.22, and proteasome maturation protein and protein extramacrochaetae (PEM, LOC5575760, AAEL002721) showed significant decreases in expression after infection (P < 0.05), with FC values of 0.88 and 0.84, respectively. The gene discussed is MUC1; the disease is infection.
