The
glh-2 message is at least 3-fold less abundant than
glh-1 mRNA in the hermaphrodite germ line. The
glh-2 signal is weakest in the distal mitotic region and most concentrated in the central meiotic region of the gonad. In addition,
glh-2 RNA is barely detectable in males. Both
glh-1 and
glh-2 RNAs are detected in all cells of young embryos, with the level of hybridization much reduced after the 8- to 10-cell stage. Thus, while
glh-1 and
glh-2 RNA differ in their levels and their patterns of accumulation in hermaphrodite and male germ lines, both glh RNAs are found throughout the early embryo.
