Manipulation of Ploidy in Caenorhabditis elegans Erlyana K. Clarke1, Katherine A. Rivera Gomez1,2, Zaki Mustachi1, Mikaela C. Murph1,3, Mara Schvarzstein1,2,3 1Brooklyn College, Biology Department, City University of New York, 2The Graduate Center, Biology Department, City University of New York, 3Advanced Science Research Center, City University of New York This method allows for the generation of tetraploid and triploid Caenorhabditis nematodes from any diploid strain. Polyploid strains generated by this method have been used to study chromosome interactions in meiotic prophase, and this method is useful for examining important basic questions in cell, developmental, evolutionary, and cancer biology.
An Introduction to Parasitic Wasps of Drosophila and the Antiparasite Immune Response Chiyedza Small*1,2, Indira Paddibhatla*1,2, Roma Rajwani1, Shubha Govind1,2 1Biology Department, The City College of New York, CUNY, 2The Graduate Center, The City University of New York Parasitoid (parasitic) wasps constitute a major class of natural enemies of many insects including Drosophila melanogaster. We will introduce the techniques to propagate these parasites in Drosophila spp. and demonstrate how to analyze their effects on immune tissues of Drosophila larvae.
