| Pattern | In hermaphrodites, the daz-1 mRNA was first detected in the germline of the L2 stage larva. Since germ cells enter the meiotic pathway at late L3, the onset of transcription of daz-1 appeared to precede the initiation of meiosis. The hybridization signal increased its intensity as the developmental stage progressed. During the larval stages, the daz-1 mRNA appeared more abundant at the distal region than the proximal region of the gonad. In young adult hermaphrodites, the daz-1 transcripts were detected at a very low level in the distal mitotic region of the gonad, began to accumulate in the meiotic transition zone, and reached the maximum level in the proximal pachytene region. The transcript level dropped sharply in mature oocytes. No hybridization signal was seen in the spermatheca. Compared to hermaphrodites, a much weaker signal was detected in the germline of adult males. | |||
