My lab just opened at Lehigh University - we study the origins, mechanisms, and impacts of the rapid evolution of the chromosome segregation machinery. I'm looking for 2 team members (postdoc and lab tech) who are passionate about evolution and cell division! See the opportunities at dudkalab.me.

When transposons jump, genomes diverge - even in cultured cells. I am happy to share our new preprint: a chromosome-scale genome assembly for Drosophila OSC cells, one of the key model systems in the piRNA field, especially for nuclear piRNA biology. 🧬🧵 (1/12)
Graphical abstract: The Drosophila OSC Genome as a resource for transposon and piRNA biology. The figure illustrates the workflow and key findings. Left: De novo genome assembly using Oxford Nanopore Technologies (ONT) long reads and Hi-C data generates a phased assembly distinguishing unique (blue) and repetitive (orange) sequences. Dot plot comparison between OSC-r1.01 and dm6 reference genomes shows overall synteny with extensive structural variation. Middle: A freely accessible UCSC genome browser session displays multi-omics data tracks including gene models, transposon insertions, chromatin accessibility, transcription, small RNAs, and histone modifications. Right: New insights into flamenco piRNA cluster biology reveal >730 kb transcribed from a single promoter without major splicing. Tethering assays demonstrate long-range silencing effects across the locus, and genome browser tracks show coordinated regulation of piRNA production, transcription, and chromatin state. This resource enables comprehensive studies of transposon regulation and piRNA pathway function in a widely-used Drosophila cell line.
