  1. ...enrichment despite lacking well-positioned nucleosomes (Fig. 3E). This noncanonical H3K27me3 enrichment resembles the pattern observed in female Drosophila GSCs, in which H3K27me3 is detectable at both inactive and active gene loci (DeLuca et al. 2020).In contrast, in CySC-like cells, H3K27me3 is most...
  2. ...and 5 kb (Colby and Williams 1993). The 5-kb repeat unit has a 242-bp insert between H1 and H3 genes. These variants are present in a number of Drosophila species, indicating that their origin predates the speciation event (Strausbaugh and Weinberg 1982). Figure 3B shows the distribution of 5- and 4...
  3. ..., hinging on the precise binding of transcription factors (TFs) and cofactors to gene regulatory elements such as promoters and enhancers. Although it is relatively routine to profile -wide DNA binding landscapes of proteins, identifying the specific proteins that bind to, and regulate the transcription of...

  4. ...transcriptionally quiescent and undergoes significant chromatin remodeling. In Drosophila, the DNA-binding protein Zelda (also known as Vielfaltig) is required for this transition and for transcriptional activation of the zygotic . Open chromatin is associated with Zelda-bound loci, as well as more generally...
  5. ...cells (RGCs) in clonally derived cell populationsWe next wanted to test the utility of the 2C-Cas9 system in the analysis of a loss-of-function phenotype in cell clones. We chose to target the atonal bHLH transcription factor 7 (atoh7) gene because a characterized loss-of-function allele (lakritz) shows...
  6. ...San Francisco, California 94080, USA. Abstract Drosophila melanogaster cell lines are important resources for cell biologists. Here, we catalog the expression of exons, genes, and unannotated transcriptional signals for 25 lines. Unannotated transcription is substantial (typically 19...
  7. ...) belong to the Drosophila subgenus (see Negre et al. 2003 for details). In order to ascertain the consequences of Drosophila HOM-C splits, we have carried out a genomic and functional characterization of the two splits present in D. buzzatii . We isolated and sequenced two BAC clones containing the lab...
  8. ...genes with no characterized role in eye development, shf and VhaPPA1–1, and two known RD genes that had not previously been characterized as direct targets of Ey, eyes absent ( eya ) and Optix. shf encodes a Drosophila homolog of Wnt-inhibitory factor-1 (WIF-1) and has recently been shown...
  9. ...intervening genes with no homology with Drosophila E(spl)-C genes. E(spl)-C in hemimetabolous insects The conclusion that E(spl) complexes are larger and more evolutionarily stable than previously thought led us to examine the newly sequenced s of the pea aphid (Acyrthosiphon pisum) and louse (Pediculus...

Results Characterization of known genes and novel TUs To catalog known genes and novel TUs, all genomic clones comprising the chr22 tiling path were subjected to a Perl...
