Abstract |
lim-7 is one of seven Caenorhabditis elegans LIM-homeodomain (LIM-HD)-encoding genes and the sole Islet ortholog. LIM-HD transcription factors, including Islets, function in neuronal and non-neuronal development across diverse phyla. Our results show that a lim-7 deletion allele causes early larval lethality with terminal phenotypes including uncoordination, detached pharynx, constipation and morphological defects. A lim-7(+) transgene rescues lethality but not adult sterility. A lim-7(+) reporter in the full genomic context is expressed in all gonadal sheath cells, URA neurons, and additional cells in the pharyngeal region. Finally, we identify a 45-bp regulatory element in the first intron that is necessary and sufficient for lim-7 gonadal sheath expression. |
