The Caenorhabditis elegans NR4A nuclear receptor is required for spermatheca morphogenesis.

ABSTRACT: The gene nhr-6 encodes the Caenorhabditis elegans ortholog of the NR4A nuclear receptor. We determined the biological functions of NHR-6 through the isolation and characterization of a deletion allele of nhr-6, lg6001. We demonstrate that nhr-6 has an essential role in the development of the C. elegans somatic gonad. Specifically, nhr-6 is required for the development of the hermaphrodite spermatheca, a somatic gonad organ that serves as the site of sperm storage and oocyte fertilization. Using a variety of spermatheca cell markers, we have determined that loss of nhr-6 function causes severe morphological defects in the spermatheca and associated spermathecal valves. This appears to be due to specific requirements for nhr-6 in regulating cell proliferation and cell differentiation during
