Effect of MOG-7 disruption on the C. elegans transcriptome

In higher eukaryotes, splicing of introns from pre-mRNAs is required for gene expression. Here, we report that Caenorhabditis elegans MOG-7 is a hybrid RNA splicing factor that contains conserved splicing domains from both yeast and mammals. Acute removal of MOG-7 from the C. elegans germline causes intron retention in the majority of genes, resulting in sterility, germline masculinization and germ cell morphology defects. Despite the deleterious consequences caused by MOG-7 loss, the germline can functionally recover to produce viable and fertile progeny once MOG-7 expression is restored through apoptotic clearance of defective germ cells. Overall design: 6 replicates in each condition; 3 conditions (No auxin treatment, 1 hour auxin; 2 hour auxin)
