	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.

7 Expression Patterns

• Primary Identifier: Expr1031598
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr2768
• Pattern: GFP-dependent fluorescence is observed organized into thin, circumferentially oriented stripes in regions of the hypodermis adjacent to muscle. This distribution is similar to that of hemidesmosome-associated cIFs. Furthermore, confocal microscopy shows that MUA-6/IFA-2::GFP codistributes with myotactin, a protein that colocalizes with hemidesmosome-associated intermediate filaments in the hypodermis of wild-type animals. MUA-6/IFA-2::GFP is also found in thin longitudinal stripes where the mechanosensory neurons interface with the hypodermis, a region of the hypodermis also shown to contain hemidesmosomes. Finally, MUA-6/IFA-2::GFP localizes to the uterine seam and prominent fibers are visualized within the uterinevulval cells. The MUA-6/IFA-2::GFP fusion protein can already be detected in embryos that are just starting to elongate. This stage is before hemidesmosome-associated intermediate filaments are recruited to regions of the hypodermis adjacent to muscle. By the three-fold stage of embryogenesis, the MUA-6/IFA-2::GFP fusion protein is detected in a pattern that is consistent with its becoming associated with hemidesmosomes.
• Subcellular Localization: Associated with hemidesmosomes.

• Primary Identifier: Expr2259
• Remark: Reporter gene fusion type not specified.
• Pattern: The A2 promoter::gfp reporter was strongly expressed in the main body hypodermis during the entire larval development, but not in the seam cells. Weak expression was detected in the ventral nerve cord.

• Primary Identifier: Expr12514
• Pattern: IFA-2::GFP protein localizes to the epidermal fibrous organelles (hemidesmosomes), the uterine seam and touch neurons. Uterine expression includes both utse and uv cells. The seam expression appears at the L4-adult molt and probably correlates with expression of IFA-2 in both the utse and the seam cells as they terminally differentiate.

• Primary Identifier: Expr2013823
• 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.
