5 Expression Patterns

• Primary Identifier: Expr12263
• Pattern: In contrast to hermaphrodites, lgc-35 is not expressed in any of the male enteric muscles, including the sphincter muscle, suggesting that it does not play a role in defecation in adult males. Like hermaphrodites, adult males expressed lgc-35 in acetylcholine motor neurons, the head mesodermal cell, and in the head interneurons AIY and AVD. In the male tail, lgc-35 is expressed in sensory rays 2, 3, 4, 5, and 9, the oblique muscle, the SPV neurons, and possibly the SPD neuron.

• Primary Identifier: Expr14314
• Pattern: The efhc-1::gfp fusion construct is specifically expressed in a small subset of ciliated mechanosensory neurons: the dopaminergic CEP, ADE and PDE neurons, and the glutamatergic OLQ neurons. Additionally, EFHC-1::GFP is found in the distal regions of sex-specific dopaminergic ray neurons in the male tail (rays 5, 7 and 9). Importantly, these expression patterns were confirmed by tagging endogenous EFHC-1 with GFP using the CRISPR/Cas9 technique.

• Primary Identifier: Expr14315
• Pattern: The efhc-1::gfp fusion construct is specifically expressed in a small subset of ciliated mechanosensory neurons: the dopaminergic CEP, ADE and PDE neurons, and the glutamatergic OLQ neurons. Additionally, EFHC-1::GFP is found in the distal regions of sex-specific dopaminergic ray neurons in the male tail (rays 5, 7 and 9). Importantly, these expression patterns were confirmed by tagging endogenous EFHC-1 with GFP using the CRISPR/Cas9 technique.

• Primary Identifier: Expr9189
• Remark: Reporter gene fusion type not specified.
• Pattern: smp- 2::gfp is strongly expressed in the male hook in close proximity to ray 1 in wild-type adult males. Expression was observed in rays 7, 8 and 9. No expression was observed in ray 1-6 lineages.

• Primary Identifier: Expr9188
• Pattern: smp- 1::gfp is strongly expressed in the male hook. Expression was observed at the cell membrane of the developing male hook precursors, the adult hook, in rays 7, 8 and 9, and in the bursa of the male tail. No expression was observed in ray 1-6 lineages.
• Subcellular Localization: [smp-1::gfp] is expressed at the cell membrane of the developing hook stage male and in adult hook cells in wild-type males.
