WormMine: ExpressionPattern Expr598

• Pattern: Male and hermaphrodite. Staining detected at all stages (embryo, L1-L4 and adults). Strong expression detected in the head and near the pharynx where numerous muscle and neuronal cells are present. Tail expression prominent near the anal sphincter. Many cells from ventral nerve cord and nerve ring stained prominently. Occasionally beta-gal was visible in hypodermal cells and in some vulval cells of adults. Young larvae displayed strong staining in head and tail region. In late stage embryos expression often seen in pairs of closely associated cells, or sometimes in a greater number of cells.
• Primary Identifier: Expr598
• Remark: This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope).
