  Transcripts of coding genes that showed significantly decreased expression in muscle. DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed. WBPaper00062325:muscle_depleted_coding-RNA

  Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic. 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_SM

  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.

  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
  Germline-intrinsic transcripts. Comparisons were made between genotypes by subtracting the mean log value of one ratio from another, and the significance of the difference was evaluated using Student t-test for two populations. For the fem-3(gf) versus fem-1(lf) direct comparison, authors performed the same analysis, except they used a Students t-test for one population. Author chose a combination of a twofold difference with a t value exceeding 99% confidence (P < 0.01), because these criteria allowed the inclusion of essentially all genes that had previously been identified as germline-enriched in a wt/glp-4 hermaphrodite comparison. Additionally, requiring a twofold difference reduced false positives, as the number of genes with two-fold difference and a P<0.01 only included ~100 genes more than with P < 0.001, and almost all genes showed germline expression by in situ hybridization.

Strain: BC12480 [C23G10.8::gfp] transcriptional fusion. PCR products were amplified using primer A: 5' [TTTTAACTTCCTCGATTTCTCCAG] 3' and primer B 5' [TCTCTTCATCGATGTTTGATCCT] 3'. Expr5316 Adult Expression: intestine; Nervous System; head neurons; unidentified cells in tail ; Larval Expression: intestine; body wall muscle; Nervous System; head neurons; unidentified cells in tail ;  
    Expr16318 SNA-1, SNA-2, SNA-3, and SUT-1 fusion proteins gave essentially identical expression patterns, being expressed in the nuclei of all somatic and germline cells, consistent with their proposed functions in spliced leader trans-splicing.  
    Expr16319 We examined the expression pattern of SNA-3::GFP throughout development. The fusion protein is found in the paternal and maternal pronuclei in one-cell embryos and expression is maintained throughout early embryogenesis, even in cells that are transcriptionally quiescent, indicating substantial parental contributions of the protein to the embryo. Somatic and germline cells express nuclear-localised SNA-3::GFP throughout postembryonic development, with expression being particularly strong in actively dividing cells, presumably reflecting the high demand for spliced leader trans-splicing.
