Abstract: In gastropod mollusks, neuroendocrine cells in the anterior ganglia have been shown to regulate growth and reproduction. As a first step toward understanding the molecular mechanisms underlying the regulation of these physiological processes in the tropical abalone Haliotis asinina, we have identified sets of POU, Sox, and Pax transcription factor genes that are expressed in these ganglia. Using highly degenerate oligonucleotide primers designed to anneal to conserved codons in each of these gene families, we have amplified by reverse transcriptase polymerase chain reaction 2 POU genes (HasPOU-III and HasPOU-IV), 2 Sox genes (HasSox-B and HasSox-C), and two Pax genes (HasPax-258 and HasPax-6). Analyses with gene-specific primers indicated that the 6 genes are expressed in the cerebral and pleuropedal ganglia of both reproductively active and spent adults, in a number of sensory structures, and in a subset of other adult tissues.
