    Description: Drosophila melanogaster is one of the most well studied genetic model organisms; nonetheless, its genome still contains unannotated coding and non-coding genes, transcripts, exons and RNA editing sites. Full discovery and annotation are pre-requisites for understanding how the regulation of transcription, splicing and RNA editing directs the development of this complex organism. Here we used RNA-Seq, tiling microarrays and cDNA sequencing to explore the transcriptome in 30 distinct developmental stages. We identified 111,195 new elements, including thousands of genes, coding and non-coding transcripts, exons, splicing and editing events, and inferred protein isoforms that previously eluded discovery using established experimental, prediction and conservation-based approaches. These data substantially expand the number of known transcribed elements in the Drosophila genome and provide a high-resolution view of transcriptome dynamics throughout development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3075879/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3075879/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graveley, Brenton R -- Brooks, Angela N -- Carlson, Joseph W -- Duff, Michael O -- Landolin, Jane M -- Yang, Li -- Artieri, Carlo G -- van Baren, Marijke J -- Boley, Nathan -- Booth, Benjamin W -- Brown, James B -- Cherbas, Lucy -- Davis, Carrie A -- Dobin, Alex -- Li, Renhua -- Lin, Wei -- Malone, John H -- Mattiuzzo, Nicolas R -- Miller, David -- Sturgill, David -- Tuch, Brian B -- Zaleski, Chris -- Zhang, Dayu -- Blanchette, Marco -- Dudoit, Sandrine -- Eads, Brian -- Green, Richard E -- Hammonds, Ann -- Jiang, Lichun -- Kapranov, Phil -- Langton, Laura -- Perrimon, Norbert -- Sandler, Jeremy E -- Wan, Kenneth H -- Willingham, Aarron -- Zhang, Yu -- Zou, Yi -- Andrews, Justen -- Bickel, Peter J -- Brenner, Steven E -- Brent, Michael R -- Cherbas, Peter -- Gingeras, Thomas R -- Hoskins, Roger A -- Kaufman, Thomas C -- Oliver, Brian -- Celniker, Susan E -- U01 HB004271/HB/NHLBI NIH HHS/ -- U01 HG004271/HG/NHGRI NIH HHS/ -- U01 HG004271-01/HG/NHGRI NIH HHS/ -- ZIA DK015600-14/Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Mar 24;471(7339):473-9. doi: 10.1038/nature09715.

    Description: Characterization of interspecies differences in gene regulation is crucial for understanding the molecular basis of both phenotypic diversity and evolution. By means of chromatin immunoprecipitation and DNA microarray analysis, the divergence in the binding sites of the pseudohyphal regulators Ste12 and Tec1 was determined in the yeasts Saccharomyces cerevisiae, S. mikatae, and S. bayanus under pseudohyphal conditions. We have shown that most of these sites have diverged across these species, far exceeding the interspecies variation in orthologous genes. A group of Ste12 targets was shown to be bound only in S. mikatae and S. bayanus under pseudohyphal conditions. Many of these genes are targets of Ste12 during mating in S. cerevisiae, indicating that specialization between the two pathways has occurred in this species. Transcription factor binding sites have therefore diverged substantially faster than ortholog content. Thus, gene regulation resulting from transcription factor binding is likely to be a major cause of divergence between related species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Borneman, Anthony R -- Gianoulis, Tara A -- Zhang, Zhengdong D -- Yu, Haiyuan -- Rozowsky, Joel -- Seringhaus, Michael R -- Wang, Lu Yong -- Gerstein, Mark -- Snyder, Michael -- New York, N.Y. -- Science. 2007 Aug 10;317(5839):815-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular, Cellular and Developmental Biology, Yale University, New Haven, CT 06511, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17690298" target="_blank"〉PubMed〈/a〉

    Description: Engineering radically altered genetic codes will allow for genomically recoded organisms that have expanded chemical capabilities and are isolated from nature. We have previously reassigned the translation function of the UAG stop codon; however, reassigning sense codons poses a greater challenge because such codons are more prevalent, and their usage regulates gene expression in ways that are difficult to predict. To assess the feasibility of radically altering the genetic code, we selected a panel of 42 highly expressed essential genes for modification. Across 80 Escherichia coli strains, we removed all instances of 13 rare codons from these genes and attempted to shuffle all remaining codons. Our results suggest that the genome-wide removal of 13 codons is feasible; however, several genome design constraints were apparent, underscoring the importance of a strategy that rapidly prototypes and tests many designs in small pieces.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lajoie, M J -- Kosuri, S -- Mosberg, J A -- Gregg, C J -- Zhang, D -- Church, G M -- New York, N.Y. -- Science. 2013 Oct 18;342(6156):361-3. doi: 10.1126/science.1241460.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24136967" target="_blank"〉PubMed〈/a〉
