	Genes with expression level regulated by genotype (N2 vs CB4856) 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_regulated_developing

6 Expression Patterns

• Primary Identifier: Expr1032083
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr16249
• Pattern: PTR-18 and GRL-7 are temporally localized along the periphery of the apical membranes of hypodermal and P neuronal progenitor cells during late embryogenesis and are subsequently targeted to lysosomal degradation before hatching. PTR-18::GFP was first detected along the apical side of surface cells that cover the whole body, which consists of hypodermal, seam, and P cells at the 3-fold stage during embryogenesis. During the early time point, the majority of the 3-fold embryos initially showed apical localization of PTR-18::GFP. As development continued, the percentage of the apical localization decreased, the fraction that exhibited localization of PTR-18::GFP in the vesicular punctate structures increased, and eventually, most of the embryos did not show its expression. These observations indicate that PTR-18::GFP first localizes at the apical side of the hypodermal, seam, and P cells, subsequently accumulates in the vesicular structures, and eventually disappears before hatching. PTR-18::GFP was alsoexpressed in the descendants of P cells, rectal epithelial F, K, and U cells, and some seam cells in late L1 larvae.
