WormMine: ExpressionPattern Expr2818

• Pattern: In hermaphrodites, the daz-1 mRNA was first detected in the germline of the L2 stage larva. The hybridization signal increased its intensity as the developmental stage progressed. 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. Compared to hermaphrodites, a much weaker signal, if any, was detected in the germline of adult males. Thus, daz-1 transcription is virtually confined to the female germline, and is regulated according to the developmental stages of oogenesis.
