"In adult C. elegans,
klp-18 mRNA expression is strongest in the female germ line. In
glp-4 hermaphrodites, which have a severely underproliferated germ line (Beanan and Strome, 1992), no
klp-18 transcript is detectable (Figure 1E). In
fem-2 hermaphrodites, which produce only oocytes (Kimble et al., 1984),
klp-18 transcript is present at high levels, and in
fem-3 gain-of-function hermaphrodites, which produce only sperm (Barton et al., 1987), it is present at approximately wild-type levels."
