• Primary Identifier: Expr4741
• Remark: Reporter gene fusion type not specified.
• Pattern: The tni-2 and tni-3 genes were also expressed in the same cells of body wall, vulval and anal muscles, but while tni-2 was uniformly expressed in body wall muscles, the tni-3 gene was strongly expressed in the head, vulval and anal muscles. Expression of tni-2::gfp was observed in the vulval and anal muscles in addition to those muscles detected with tni-2::lacZ. This was the result of the inclusion of a longer 5' upstream region of tni-2 that includes the NdE-box enhancer for vulval expression.

The tni-3::lacZ construct was expressed in all the body wall muscles from the L1 to adult stages. In the adult stage, tni-3::lacZ expression in body wall muscles became weaker with time although strong expression persisted in the head and vulval muscles.

Using a muscle-specific marker, these cells were identified as head body wall muscle cells.
