Project description:Long noncoding RNAs (lncRNAs) are a diverse class of RNAs that are critical for gene regulation, DNA repair and splicing, and have been implicated in cancer, stress response, and development. However, the function of many lncRNAs remains unknown. In Drosophila melanogaster, U snoRNA host gene 4 (Uhg4) encodes an antisense long noncoding RNA that is host to seven small nucleolar RNAs (snoRNAs). Uhg4 is expressed ubiquitously during development and in all adult fly tissues with maximal expression in ovaries; however, it has no annotated function(s). Here, we used CRISPR-Cas9 germline gene editing to generate multiple deletions spanning the promoter region and first exon of Uhg4. Mutant flies were sterile, showed delayed development and decreased viability, and changes in sleep and responses to stress. Whole genome RNA sequencing of Uhg4 deletion flies and their controls identified coregulated genes and genetic interaction networks. Gene ontology analyses highlighted a broad spectrum of biological processes, including morphogenesis, stress response, and regulation of transcription and translation. Thus, Uhg4 is a lncRNA essential for reproduction with pleiotropic effects on multiple fitness traits.

Project description:Thomas Hunt Morgan and colleagues identified variation in gene copy number in Drosophila in the 1920s and 1930s and linked such variation to phenotypic differences [Bridges, C. B. (1936) Science 83, 210]. Yet the extent of variation in the number of chromosomes, chromosomal regions, or gene copies, and the importance of this variation within species, remain poorly understood. Here, we focus on copy-number variation in Drosophila melanogaster. We characterize copy-number polymorphism (CNP) across genomic regions, and we contrast patterns to infer the evolutionary processes acting on this variation. Copy-number variation in D. melanogaster is non-randomly distributed, presumably due to a mutational bias produced by tandem repeats or other mechanisms. Comparisons of coding and noncoding CNPs, however, reveal a strong effect of purifying selection in the removal of structural variation from functionally constrained regions. Most patterns of CNP in D. melanogaster suggest that negative selection and mutational biases are the primary agents responsible for shaping structural variation.
