  1. ..., the factors influencing such regulation are poorly understood. In Caenorhabditis elegans, 62% of genes are trans-spliced to a specific spliced leader (SL1), which replaces part of the native 5′ untranslated region (5′ UTR). Given the pivotal role the 5′ UTR plays in the regulation of translational efficiency...
  2. ...categorized the 5′ ends of RNA reads based on the proximity of their 5′ end to the trans-splicing site (TSS; as many C. elegans gene mRNAs are trans-spliced after transcription, the 5′-most nucleotide of the spliced mRNA differs from the transcription start site). Decapping leaves a 5′ monophosphate (Wang et...
  3. ...communication between cis-regulatory elements. Many organisms, including S. cerevisiae, C. elegans, and A. thaliana contain cohesin but lack CTCF. Here, we used C. elegans to investigate the function of cohesin in 3D organization in the absence of CTCF. Using Hi-C data, we observe cohesin-dependent features...
  4. ...more peaks in introns than worms. The distribution of peaks in C. elegans is slightly farther upstream of the TSS than in Drosophila, perhaps reflecting the fact that for many C. elegans gene models the annotated TSS is the site of trans-splicing, with the start of transcription occurring further...

  6. ...most genes in C. elegans are trans-spliced to a 22-nt leader RNA (Blumenthal 2012), leading to removal and degradation of the initial 5′ sequence between the promoter and the trans-splice site, the beginning of the mature mRNA does not usually correspond to the transcription initiation site. Therefore...
  7. ...of the 5′-most 10–15 bases prevented us from examining splice leader-based trans splicing, a common RNA modification in C. elegans (see discussion in Supplemental Material). The average length of unique splice isoforms identified in our sequencing libraries was 1596 nt (Fig. 1E,F and discussed below...
  8. ...reveal many more. Operons About 70% of C. elegans transcripts are trans-spliced, with the SL1 splice leader used for genes with independent promoters and the Figure 2. The relative abundance of novel versus known junctions in alternatively spliced pairs within WormBase gene models. For each splice...
