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.
