	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
	Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons.	DESeq. False discovry rate (FDR) < 0.1.	WBPaper00048988:neuron_expressed
Osmotic stress	Transcripts that showed significantly altered expression with 500 mM salt (NaCl) vs 100 mM salt when no food was present	DESeq(version 1.10.1), FDR < 0.05.	WBPaper00050726:OsmoticStress_regulated_NoFood
	Genes that were upregulated in lin-15B(n744).	For each gene in each microarray hybridization experiment, the ratio of RNA levels from the two samples was transformed into a log2 value and the mean log2 ratio was calculated. The log2 ratios were normalized by print-tip Loess normalization (Dudoit and Yang, 2002). All genes with a false discovery rate of <= 5% (q <= 0.05) (Storey and Tibshirani, 2003) and a mean fold-change ratio of >= 1.5 were selected for further analysis.	WBPaper00038168:lin-15B(n744)_upregulated
	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

Reduced humidity (98% relative humidity).	Genes that were down-regulated after one day exposure to reduced humidity (98% relative humidity) according to microarray analysis.	Multiple hypothesis testing with the Benjamini-Hochberg correction was applied on calculated p-values. A change in the expression level was considered to be significant if the adjusted p-value was less than 0.001.	WBPaper00044578:reduced-humidity_downregulated_microarray
	Transcripts that showed significantly increased expression in clk-1(qm30) 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:clk-1(qm30)_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
	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.

The differentially expressed genes were filtered by fold change more than 2 and adjusted p-value < 0.05. The scatter plots were generated by the plot function in R.

• Primary Identifier: Expr3457
• Remark: With a translational full-length rom-1::gfp fusion construct, no transgenic lines were obtained that consistently expressed ROM-1::GFP. Moreover, a genomic DNA fragment encompassing the entire rom-1 locus failed to produce stable transgenic lines even when injected at relatively low concentrations (10 ng/$(B&L(Bl), suggesting that elevated levels of ROM-1 are toxic to the animals.
• Pattern: The transcriptional rom-1::nls::gfp reporter was widely expressed in somatic cells throughout development. Surprisingly, no rom-1::nls::gfp expression was in the gonadal AC before the L4 stage, while consistent expression was observed in the Pn.p cells and the Pn.a-derived neurons from the L1 stage on. In early L2 zhIs5 larvae, the six VPCs expressed rom-1::nls::gfp at equal levels. The Pn.p cells that are not part of the vulval equivalence group and had fused to hyp7 at the end of the L1 stage showed relatively higher rom-1::nls::gfp expression than the VPCs (for example, P1.p, P2.p, and P9.p). Toward the end of the L2 stage, rom-1::nls::gfp expression decreased in distal VPCs adopting the 3N0 uninduced fate and persisted in the proximal VPCs adopting induced vulval fates. In 60% of zhIs5 animals, there is an up-regulation of rom-1::nls::gfp in P6.p, and in 35% and 45% of the cases, rom-1::nls::gfp expression was higher in P5.p and P7.p, respectively (n = 20). After vulval induction, rom-1::nls::gfp was down-regulated in the primary and secondary descendants of P5.p, P6.p and P7.p, while the tertiary descendants of P3.p, P4.p, and P8.p again expressed high levels of rom-1::nls::gfp after they had fused with hyp7. Expression of rom-1::nls::gfp was observed in the AC and other cells of the somatic gonad only beginning in the L4 stage, before the AC fused with the uterine seam cell and persisting after fusion.

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.
