• Primary Identifier: Expr13134
• Pattern: Refers to NEXTDB In-situ hybridization pattern in the adult gonad. Distal + central

• Primary Identifier: Expr10651
• Pattern: PUF- 8::GFP is expressed throughout the distal end of the gonad, with slightly lower levels within the first third to half of the proliferative zone. Protein levels gradually decrease proximally until eventually plateauing at ~40 cell diameters, well beyond where all cellsnormally have entered into meiotic prophase. PUF-8 is at its maximum expression level in the approximate region of the proliferative zone where cells are likely entering pre-meiotic S-phase.

• Primary Identifier: Expr15956
• Subcellular Localization: Immunofluorescent imaging revealed FLAG signal on the distal gonad of dissected ges-1p::FLAG vpr-1 transgenic worms. Z-stack imaging showed that the N-terminal FLAG signal of VPR-1 is restricted to the surface of the somatic gonad. No FLAG staining was detected inside the syncytium, on oocytes, fertilized embryos, or in the proximal gonad. Taken together, the results provide strong evidencethat N-terminal FLAG-tagged VPR-1 is secreted from intestinal cells and travels to the distal gonad to modulate gonadal development.
