	Genes with expression level regulated by genotype (N2 vs CB4856) and age at old adults stage (214 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_aging

	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

• Primary Identifier: Expr1030216
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr16157
• Pattern: We confirmed the expression of this construct in F and U, but detected expression at lower frequency and level in other hindgut cells in hermaphrodites grown at 20C. Expression is also observed in K and K'. In wild type, cdh-3::gfp expression is never observed in Y. In contrast, the B cell expresses cdh-3::gfp at low levels in wild type.

• Primary Identifier: Expr1614
• Remark: Reporter gene fusion type not specified.
• Pattern: At the beginning of embryonic morphogenesis, all ten pairs of lateral epidermal cells, the seam cells, express cdh-3::lacZ. cdh-3::GFP expression in these cells is observed at hatching and throughout subsequent postembryonic development. During the last larval stage (L4) the 15 pairs of seam cells generated during larval development fuse to form two continuous lateral syncytia, surrounded by hyp7. cdh-3::GFP expression correlates with seam cell identity during these postembryonic divisions; it is not observed in daughters that fuse with hyp7 or adopt other fates. In embryos undergoing morphogenesis, lacZ is expressed in a single large nucleus, whose size and position is consistent with that of the excretory cell. This identification is reinforced by the observation that in many newly hatched L1 larvae, low levels of GFP expression are visible in the excretory cell. This expression of cdh-3-reporter genes was observed only during late embryogenesis and in some newly hatched L1s (the latter may be due to perdurance of the GFP fusion protein), but not at later stages. Several other cells expressed the cdh-3 reporter constructs during embryonic morphogenesis; as in the seam cells this expression continued upon hatching. In the tail two cells, hyp10 and hyp11, show strong GFP expression that persists only during the first larval stage. Strong expression was observed in cells that form interfacial epithelia between the intestinal epithelium and the epidermis. Two cells that form part of the rectal epithelium, designated F and U, express cdh-3::GFP during embryonic morphogenesis and throughout larval development. In the anterior of embryos undergoing morphogenesis there were several cells expressing cdh-3::lacZ, and in larvae and adults, GFP expression is seen in nine cell bodies located just anterior to the first bulb of the pharynx. Processes extend anteriorly from these cell bodies and terminate at the level of the buccal capsule. Based upon the location of the cell bodies and the morphology of the processes, these cells were identified as the anterior and posterior arcade cells. Expression pattern of the pJP#38 construct in males indicated expression in the male tail and several male-specific neurons, however the expression pattern is complicated and the cell identity were not determined. cdh-3::GFP expressed in the developing hermaphrodite vulva. GFP first expressed in the anchor cell in L3 larvae. A little later expression were seen in those vulval cells that are closest to the anchor cell and are beginning to invaginate. As vulval morphogenesis continues all of the cells that invaginate to form the vulva are expressing GFP. During this period, the uterine epithelium closest to the invaginating vulval cells begins to express cdh-3::GFP and the anchor cell fuses with the multinucleate uterine seam cell (utse), which also begins to express cdh-3::GFP. Expression continues in these cells into the adult stage, though at somewhat reduced levels, which may perhaps be due to perdurance of the fusion protein, since older adults show much reduced fluorescence compared with younger ones. During the time that the vulva is forming, cdh-3::GFP expressed in the six VC neurons located in the ventral nerve cord and the two HSNs located just posterior and dorsal to the developing vulva. These cells begin to extend processes at about this time, and GFP expression continues in these cells and their processes throughout the remainder of larval development and into adulthood.

• Primary Identifier: Expr14865
• Pattern: We also used smFISH to examine the expression of cdh-4 and cdh-3. Consistent with transgenic reporter studies (Sundararajan et al., 2014), we observed cdh-4 mRNA spots in the Q neuroblasts, as well as a wide range of other cells, including the neighboring seam and P cells, ventral nerve cord neurons and cells in the head region. In contrast, we found that during the initial polarization and migration phase, cdh-3 was specifically expressed in the Q neuroblasts, with additional expression only in a few unidentified cells in the head. Similar to unc-40, there was no significant difference in expression between QL and QR. Moreover, for both cdh-3 and cdh-4, the expression level correlated with migration distance (cdh-3 QL, Spearman r = 0.5765, p < 0.0001, QR, Spearman r = -0.4838, p < 0.0004; cdh-4 QL, Spearman r = 0.3176, p < 0.03, QR, Spearman r = -0.5070, p < 0.0004), indicating that expression increases during polarization and migration.
