Genes were tested for differential expression between each mutant strain and wild-type using edgeRs glm method. Briefly, negative binomial models were fitted and dispersion estimates obtained. These were then used to calculate average levels of change between conditions and determine differential expression, using the generalized linear model likelihood ratio test. For each comparison, genes with less than 5 CPM were filtered and those with at least 50% change and False Discovery Rate (FDR) of 1% or less were considered differentially expressed.

	Genes that showed expression levels higher than the corresponding reference sample (L3/L4 all cell 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.

• Remark: Deconvolution microscopy to generate high resolution images of the nuclei of two-cell embryos stained with mAb 6C4 and DAPI. The relative time of each nucleus in the cell cycle was inferred by comparing the staining patterns of the AB and P1 blastomeres; the AB blastomere division occurs before that of the P1 blastomere. The morphology of DAPI staining and presence of a nuclear membrane were used as additional landmarks of cell cycle progression. No other cellular expression pattern described.
• Subcellular Localization: Interphase nuclei had no detectable mAb 6C4 reactivity. Nuclei that are in the earliest stages of chromosome condensation do not stain with mAb 6C4. Staining with mAb 6C4 was first observed in prophase nuclei that contain condensed chromosomes. At this stage, mAb 6C4 staining was observed as dots distributed throughout the nucleus; many of these dots colocalize with the chromosomes. These chromosome-associated dots are widely dispersed along the entire length of each chromosome. Later in prophase, mAb 6C4 stained structures located on opposite sides of each chromosome. In metaphase, when the chromosomes are aligned at the equatorial plane, chromosomes were oriented with each mAb 6C4 stained structure facing one centrosome. At anaphase, sister chromatids separated with the mAb 6C4 stained side on the poleward face of each sister chromatid. No mAb 6C4 staining was detectable by late anaphase. These results show that there is dynamic localization of the mAb 6C4 antigen to chromosomes throughout mitosis. mAb 6C4 Staining during meiosis During meiosis, C. elegans chromosomes lack a trilaminar kinetochore structure, and attachment to the meiotic spindle is mediated through the chromosome ends. No mAb 6C4 nuclear staining was detected in the mitotic region of the gonad of the hermaphrodite nor in oocytes arrested at diakinesis of prophase I. After fertilization, embryos exit prophase I arrest and undergo two consecutive rounds of division to form two polar bodies. Staining with mAb 6C4 was detected on meiotic chromosomes after fertilization and before first olar body formation. The mAb 6C4 staining pattern was observed as a halo surrounding the meiotic chromosomes.
