lin-36::GFP was expressed in the nuclei of the P(3-8).p cells and their descendants during vulval cell determination, division and invagination. Similar observations have been made with an independently constructed
lin-36::GFP reporter. Besides the P(3-8).p cells, many other cells expressed GFP in strains bearing this reporter construct. Most notably, neurons of the head, tail and ventral cord expressed
lin-36::GFP throughout development, and sporadic fluorescence was infrequently observed in the germline. Very weak staining was observed in hypodermal and intestinal nuclei.
