A fusion gene construct containing the bacterial chloramphenicol acetyltransferase (CAT) gene under the control of CyIIIa actin gene regulatory sequences was injected into unfertilized eggs of the sea urchin Strongylocentrotus purpuratus, and early pluteus stage embryos that developed from these eggs were fixed and sectioned for analysis by in situ hybridization. A [^3H]RNA antisense probe for CAT mRNA was hybridized to 5-μm embryo sections. Autoradiographic signal denoting the presence of CAT mRNA was detected only over aboral ectoderm cells, in which the CyIIIa gene is normally expressed, and not over any recognizable regions of gut or oral ectoderm included in the same sections.
