Expression Pattern :

Pattern  The ida-1 gene promoter-driven GFP expression pattern in males differs from hermaphrodites, especially in the tail, where many more fluorescent cells are observed. Male larvae appear very similar to hermaphrodite larvae, the only difference being that the PVP neurons in the preanal ganglion showed higher GFP expression levels. It was concluded that all neurons expressing GFP in the hermaphrodite pharyngeal nerve ring and in the tail also express GFP in males. In adult males, additional fluorescence is seen in neurons anterior to the nerve ring, in the ventral cord and many more in the tail. The four additional GFP-expressing cells in the procorpus just anterior to the pharyngeal bulb have not been identified. Expression in the male-specific CEM neurons at the anterior end of the nerve ring appeared variable. The hermaphrodite-specific cells VC, HSN, and uv1 observed to express GFP are not found in males. Nonetheless, several cell bodies in the male ventral cord expressed GFP. Dorsally directed processes emanate from them, which identifies them as CAn, a set of eight motoneurons. As in hermaphrodites, PDE weakly expressed GFP. In the male tail, about 20 neurons express GFP. They include PHA, PHB, PHC, and PVP in the preanal ganglion, which are already seen in larvae. Some of the rays contain GFP-filled axons that extend all the way to the tip of the ray. Rays 2, 8, and 9 show the highest expression levels; axons of rays 1, 4, and 6 fluoresce more weakly. No GFP expression is observed in the spicules. Primary Identifier  Expr843
Remark  Reporter gene fusion type not specified. To analyze ida-1 gene expression in males, the pida-1::GFP transgenic strain BL5715 was crossed with the him-8 (high incidence of males) mutant strain BW1663. cgc6469 mentioned that this reporter gene is transcriptional fusion.
