WormMine: ExpressionPattern Expr576

• Pattern: In adult hermaphrodites, mex-1 mRNA is detected in the syncytial core of the gonad and in oocytes at all stages of maturation. In 1 and 2-cell stage embryos, mex-1 mRNA is distributed uniformly, but then appears to be degraded rapidly in somatic blastomeres but remains in germ line blastomeres in subsequent divisions. After P4 divides, mex-1 mRNA is not detected.
• Primary Identifier: Expr576
• Remark: Maternal effect. early embryo(author) = blastula + gastrulating embryo(curator).
