Genetics Detection of Homologous Recombination Intermediates via Proximity Ligation and Quantitative PCR in Saccharomyces cerevisiae Diedre Reitz1, Jérôme Savocco2, Aurèle Piazza2, Wolf-Dietrich Heyer1,3 1Department of Microbiology & Molecular Genetics, University of California, Davis, 2Laboratory of Biology & Modeling of the Cell, École Normale Supérieure de Lyon, 3Department of Molecular & Cellular Biology, University of California, Davis The D-loop capture (DLC) and D-loop extension (DLE) assays utilize the principle of proximity ligation together with quantitative PCR to quantify D-loop formation, D-loop extension, and product formation at the site of an inducible double-stranded break in Saccharomyces cerevisiae. Biology The Tomato/GFP-FLP/FRT Method for Live Imaging of Mosaic Adult Drosophila Photoreceptor Cells Pierre Dourlen1,2, Clemence Levet1, Alexandre Mejat1, Alexis Gambis3, Bertrand Mollereau1 1Laboratory of Molecular Biology of the Cell, Ecole Normale Supérieure de Lyon, 2INSERM U744, Institut Pasteur de Lille, Université Lille-Nord de France, 3Howard Hughes Medical Institute, Laboratory of Apoptosis and Cancer, The Rockefeller University The Tomato/GFP-FLP/FRT method involves visualizing mosaic photoreceptor cells in living Drosophila. It can be used to follow individual photoreceptor cell fates in the retina for days or weeks. This method is ideal for studies of retinal degeneration and neurodegenerative diseases or photoreceptor cell development.
