Table 1. Microarray expression clusters showing significant overlap with genes up or down regulated upon germline ablation in P. pacificus.

DAF-16, TGF-beta and Dauer related clusters
Expression cluster	sigScore.UP	sigScore.DOWN
Murphy_etal_cgc5976_Class1	1.35	0
Murphy_etal_cgc5976_Class2	0	1.55
Sinha_etal_ppa_dauers_UP	4.97	0
Sinha_etal_ppa_dauers_DOWN	29.91	302.83
Roberts_etal_2010_DBL-1-DOWN	0	49.64
Roberts_etal_2010_DBL-1-UP	0	12.24

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^*Expression clusters derived from our as yet unpublished data on pathogen response of wild-type P. pacificus to Serratia marcescens, Xenorhabdus nematophila, Staphylococcus aureus, and Bacillus thuringiensis DB27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).
