	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
	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.

	Genes that showed oscillating mRNA expression level throughout the 16 hour time courses from L3 larva to young adult.	The following three lines of R code were used to perform the classification: increasing <-2*amplitude-PC1 < -1.7; oscillating <-!increasing & (amplitude > 0.55); flat <-!increasing & !oscillating; Note that the amplitude of a sinusoidal wave corresponds to only half the fold change between trough and peak.

	Transcripts that showed significantly decreased expression in set-2(tm1630) animals at embryo stage, comparing to in N2 animals.

	Genes regulated by DAF-12, according to whole transcriptome profiling to compare genome-wide regulatory influences of DPY-21 and SET-4 to those of the key transcription factors controlling dauer arrest in eak-7;akt-1 animals, DAF-16 and DAF-12.	Authors identified genes differentially expressed between wild-type and eak-7;akt-1 double mutant animals [fold change >= 1.5 and false discovery rate (FDR) < 0.05]. Authors then compared the transcriptomes of eak-7;akt-1 double mutants to those of eak-7;akt-1 animals harboring mutations in dpy-21, set-4, daf-16, or daf-12, and identified genes that are differentially expressed in the opposite direction as in wild-type relative to eak-7;akt-1. Annotated gene expression data output from CuffDiff v2.2.1 was read into R version 3.2.1 for six comparisons: eak-7;akt-1 compared to (1) wild-type, (2) daf-16(mu86);eak-7;akt-1, (3) daf-12;eak-7;akt-1, (4) set-4(n4600);eak-7;akt-1, (5) set-4(dp268);eak-7;akt-1, and (6) dpy-21;eak-7;akt-1. Authors filtered genes by the following criteria: (1) status = OK for wild-type vs. eak-7;akt-1, (2) fold change (FC) >= 1.5 or FC <= 1/1.5 for wild-type vs. eak-7;akt-1 and (3) FDR < 0.05 for at least two separate comparisons.

	Genes uniquely expressed in endoderm, according to RNAseq studies on blastomere (with isolated AB, MS, E, C, D founder cells dividing in vitro) time course and whole embryo time course.	Germ layers were assigned by correlating the average expression with germ-layer-specific patterns with a cutoff of 0.6 correlation with the following idealized vectors: endoderm = [00100]; ectoderm = [10000]; mesoderm = [01011], where the order is AB, MS, E, C and P3. Germ-layer genes were defined according to the sum of the genes identified by the clusters and are indicated in Fig. 2b. Authors further filtered the germ-layer gene sets by keeping only those genes whose expression was partitioned across the germ layers such that at least two-thirds of the expression was in that germ layer.

6 Expression Patterns

• Primary Identifier: Expr1151972
• Pattern: Developmental gene expression time-course. Raw data can be downloaded from ftp://caltech.wormbase.org/pub/wormbase/datasets-published/hashimshony2015

• Primary Identifier: Expr13327
• Pattern: As indicated by gfp, the expression of klf-2 was not noticeable in embryos but prominent in all four larval and adult stages. During larval development, the gfp expression was continuously observed along the length of the intestine during the developing larva and adult stages, suggesting that klf-2 is mainly located in intestine.

• Primary Identifier: Expr2012951
• 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).
