  Pattern: In the pAB::GFP fusion, expression was seen in some pioneering neurones of the nerve ring, beginning at the early comma stage. At the two-fold stage, expression was detected in some 10 neurones in the head that extend axons into the nerve ring, and in two neurones in the tail that extend processes anteriorly. This expression pattern was confirmed by immunohistochemistry with MAb 16-48-2. At the three-fold stage, expression was seen in all DA motoneurones and persisted while they pioneered the dorsal nerve chord. It was also seen in four to six neurones in each of the four head ganglia, including ALA and RID in the dorsal ganglion, and four of the six neurones of the terminal bulb, including M5. In the tail, two neurones in the pre-anal ganglion and six in the lumbar ganglion, including PVQL and PVQR, showed pAB::GFP expression. Additionally, a transient expression was seen in the four rows of bodywall muscle cells in the embryo. After hatching, in L1 larvae, the expression domain extended to amphid and phasmid socket cells, and subsequently in L2 larvae to all the newly born AS motoneurones. In hermaphrodite L3 larvae, expression was seen in the sex myoblasts subsequent to their anterior migration towards the position of the presumptive vulva, and in adult worms at a high level in the vulval muscles vm1 and vm2. In males, expression was seen in the diagonal and spicule retractor muscles.
