	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
	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.

For log2 fold changes > 0.00001 the values > 81.25th percentile were defined as up-regulated and for log2 fold changes < -0.00001 the values < 18.75th percentile were defined as down-regulated.

	Transcripts expressed in intestine, according to PAT-Seq analysis using Pges-1-GFP-3XFLAG mRNA tagging.	Cufflinks FPKM value >=1.	WBPaper00050990:intestine_expressed
	Genes with expression level regulated by genotype (N2 vs CB4856) and age at L3 larva and Late reproduction stage (96 hours at 24 centigrade).	For model 2, authors used 100 permutations to estimate the FDR threshold. Per permutation, genotypes and ages were independently randomly distributed, keeping the among-gene structure intact. Then for each spot (23,232) on the array, model 2 was tested. The obtained P-values were used to estimate a threshold for each of the explanatory factors. Authors also used a genome-wide threshold of -log10 P-value = 2, which resembles an FDR of 0.072 and 0.060 for marker and the interaction age-marker for the developing worms and FDR of 0.050 and 0.065 for marker and age-marker for the aging worms. For the physiological age effect, authors used a log10 P-value = 8 in developing worms (0.012 FDR) and -log10 P-value = 6 (0.032 FDR).	WBPaper00040858:eQTL_age_regulated_developing

7 Expression Patterns

• Primary Identifier: Expr16119
• Subcellular Localization: To investigate the expression and subcellular localization of GRDN-1 in A/PQR, we expressed the functional GFP-tagged full-length GRDN-1a isoform (henceforth referred to as GRDN-1::GFP) under its endogenous regulatory sequences (Nechipurenko et al., 2016). GRDN-1::GFP was expressed in A/PQR and localized to the cilia base in both neurons in adult hermaphrodites. The dynein light intermediate chain protein XBX-1 localizes to the basal body and undergoes bidirectional movement along the ciliary axoneme (Schafer et al., 2003). The GRDN-1::GFP signal overlapped with the proximal-most region of the XBX-1::tagRFP signal in PQR, suggesting that GRDN-1 localizes to the basal body in PQR. GRDN-1 also associates with the basal body in the distal segment of the outgrowing AQR dendrite.

• Primary Identifier: Expr13138
• Subcellular Localization: GRDN-1a::GFP was broadly expressed during embryogenesis and was enriched at the presumptive nose starting at mid-embryogenesis, coinciding with the time period of sensory neuron differentiation and ciliogenesis (Sulston et al., 1983).The subcellular localization of GRDN-1a::GFP was reminiscent of that previously reported for BB and TZ proteins in embryonic head sensory neurons (e.g., Dammermann et al., 2009). Consistent with this notion, GRDN-1a::GFP was present at the AWB cilia base in larvae, and co-localized with the BB markers DYF-19 and GASR-8 in the PHA/PHB ciliated tail neurons in L1 larvae and adult AWB neurons, respectively. Intriguingly, GRDN-1a::GFP appeared to be enriched at the proximal ends of centrioles, and was completely excluded from the TZ marked by MKS-5::tagRFP. Together, these observations suggest that Girdin is localized to the BBs in C. elegans sensory neurons.
