Vulval expression. In the vulva,
cog-1::gfp is expressed from early L4 to the adult. Cells that express are vulC [P5.ppa(l/r), P7.pap(l/r)], vulD (P5.ppp, P7.paa), vulE(P6.pppl, P6.pppr, P6.paal, P6.paar), and vulF (P6.ppal, P6.ppar, P6.papl, P6.papr). The expression is considerably brighter in vulC and vulD than in vulE and vulF. Occasionally, expression in vulB and vulA was observed. Male expression. The expression of
cog-1::gfp in the male was scored mostly in animals containing an extrachromosomal array containing the SmaI insertion.
cog-1::gfp is expressed during proctodeal development. eL.aav and eR.aav express
cog-1. In addition, proctodeal cells B.pap and B.pppa express
cog-1::gfp. Additional expressing cells observed in occasional males include: rep, and P11.pp progeny. No gonadal cells in the male, including the linker cell, expressed
cog-1::gfp in any stage of development.
