	Maternal class (M): genes that are called present in at least one of the three PC6 replicates.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_M

	Genes with increased RNA expression after 24 hours rotenone treatment	EdgeR provides statistical routines for determining differential expression in digital gene expression data using a model based on the negative binomial distribution. The resulting p-values were adjusted using the Benjamini and Hochbergs approach for controlling the false discovery rate (FDR). Transcripts with an adjusted p-value smaller 0.05 were assigned as differentially expressed.	WBPaper00044426:rotenone_24h_upregulated
Starvation	Starvation-induced transcripts that showed significantly increased expression in post dauer animals comparing to wild type control.	edgeR	WBPaper00053713:Starvation-induced_postdauer_vs_control_upregulated
	Genes that showed expression levels higher than the corresponding reference sample (L2 all cell reference).	A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes.

	Proteins that showed significantly decreased expression after 1-day-old wild type adults were exposed to cisplatin (300ug per mL) for 6 hours.

	Transcripts that showed significantly increased expression in isp-1(qm150) comparing to in N2.	Differential gene expression analysis was performed using the quasi-likeli-hood framework in edgeR package v. 3.20.1 in R v. 3.4.1.	WBPaper00053810:isp-1(qm150)_upregulated
	Transcripts that showed significantly increased expression in nuo-6(qm200) comparing to in N2.	Differential gene expression analysis was performed using the quasi-likeli-hood framework in edgeR package v. 3.20.1 in R v. 3.4.1.	WBPaper00053810:nuo-6(qm200)_upregulated
