The sys-1 gene and sexual dimorphism during gonadogenesis in Caenorhabditis elegans.
In wild-type Caenorhabditis elegans, the hermaphrodite gonad is a symmetrical structure, whereas the male gonad is asymmetric. Two cellular processes are critical for the generation of these sexually dimorphic gonadal shapes during early larval development. First, regulatory "leader" cells that control tube extension and gonadal shape are generated. Second, the somatic gonadal precursor cells m...
متن کاملgon-2, a gene required for gonadogenesis in Caenorhabditis elegans.
The gonad of the Caenorhabditis elegans hermaphrodite is generated by the postembryonic divisions of two somatic precursors, Z1 and Z4, and two germline precursors, Z2 and Z3. These cells begin division midway through the first larval stage. By the end of the fourth larval stage, Z1 and Z4 produce 143 descendants, while Z2 and Z3 give rise to approximately 1000 descendants. The divisions of Z2 ...
متن کاملReciprocal asymmetry of SYS-1/ -catenin and POP-1/TCF controls asymmetric divisions in Caenorhabditis elegans
-Catenins are conserved regulators of metazoan development that function with TCF DNA-binding proteins to activate transcription. In Caenorhabditis elegans, SYS-1/ -catenin and POP-1/TCF regulate several asymmetric divisions, including that of the somatic gonadal precursor cell (SGP). In the distal but not the proximal SGP daughter, SYS-1/ -catenin and POP-1/TCF transcriptionally activate ceh-2...
متن کاملUsing RNA-Mediated Interference to Investigate the Role of Novel Proteins in Caenorhabditis elegans Gonadogenesis
During development, cells divide, differentiate into various cell types, and organize into functional tissues and organs. We are interested in understanding the cellular and molecular basis of organ formation in the nematode Caenorhabditis elegans. To this end, we are investigating two novel proteins that have a role in gonadogenesis, SYS-1 and NUD-1. SYS-1 was identified via a genetic screen f...

beta-Catenins are conserved regulators of metazoan development that function with TCF DNA-binding proteins to activate transcription. In Caenorhabditis elegans, SYS-1/beta-catenin and POP-1/TCF regulate several asymmetric divisions, including that of the somatic gonadal precursor cell (SGP).
