	Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons.	DESeq. False discovry rate (FDR) < 0.1.	WBPaper00048988:neuron_expressed
	Genes that showed expression levels higher than the corresponding reference sample (embryonic 24hr 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.

	Transcripts expressed in intestine, according to PAT-Seq analysis using Pges-1-GFP-3XFLAG mRNA tagging.	Cufflinks FPKM value >=1.	WBPaper00050990:intestine_expressed
	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

	Transcripts that showed significantly altered expression after 24 hour exposure to nitroguanidine (NQ).	Multivariate permutation tests with random variance model implemented in BRB-Array Tools version 4.5 were performed to infer differentially expressed genes (DEGs). One thousand random permutations were computed per chemical class (i.e., a group of 16 arrays or samples). The confidence level of false discovery rate assessment was set at 80%, and the maximum allowed portion of false-positive genes was 10%.	WBPaper00055899:nitroguanidine_regulated

	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.

7 Expression Patterns

• Primary Identifier: Expr2034143
• Pattern: Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type. Interactive visualizations are available as a web app (https://cello.shinyapps.io/celegans/) and can also be installed as an R package (https://github.com/qinzhu/VisCello.celegans).

• Primary Identifier: Expr1337
• Remark: Reporter gene fusion type not specified.
• Pattern: Pers Comm. from Rachel Aronoff 11-29-01: clear expression in adult muscle and in embryonic cells of many lineages, including myocytes.
• Subcellular Localization: SMG-4:GFP localizes both to nuclear and cytoplasmic compartments. Confocal microscopic resolution, furthermore, reveals bright puncta both around nuclei and extending into the cytoplasm. In the embryo, GFP luorescence is visible both in the nucleus and cytoplasm of many cells, although the nuclear signal is stronger. Intense GFP puncta can also be seen in or around the nucleus. From successive confocal series through individual nuclei, the very bright GFP puncta appear to be perinuclear, as the signal can sometimes be seen radially distributed around the nucleus. Such perinuclear accumulation can also occasionally be seen by standard fluorescence microscopy. However, in the confocal microscope, additional bright GFP puncta extending into the cytoplasm are also frequently evident.

• Primary Identifier: Expr110
• Remark: Other strains-- UL374, UL372 late embryo(author) = 3-fold embryo + fully-elongated embryo(curator).
• Pattern: Expression is seen from 3 fold embryonic stage to adulthood. Staining mostly consists of a few posterior intestinal nuclei. Occasionally anterior intestinal nuclei are also evident. Staining is strong in larvae but weaker in adults. A few nuclei, probably neuronal, are sometimes seen in the adult head. The 5' upstream region is 3.8kb.
