Microarray expression clusters showing significant overlap with genes up or down regulated upon germline ablation in P. pacificus.

Significance scores are −log10 of the p-values obtained in a 2×2 Fisher's exact test, and have been set to zero in case of non-significant enrichment where p-value >0.05.*Expression clusters derived from our as yet unpublished data on pathogen response of wild-type P. pacificus to Serratia marcescens, Xenorhabdus nematophila, Staphylococcus aureus, and Bacillus thuringiensis DB27 (AS, RR, II and RJS, manuscript submitted).
