Abstract HasPOU-III is expressed in multiple cell types during the first 3 days of development of the gastropod Haliotis asinina. HasPOU-III expression begins in two bilaterally symmetrical sets of cells on the ventral ectodermal surface of the trochophore larva; one set are putative foot mucous cells. After torsion, HasPOU-III transcripts transiently appear in the developing ganglia of the central nervous system. At the end of larval morphogenesis, HasPOU-III expression is initiated in dorsoposterior cells of the visceral mass, in the posterior cells of the statocyst and in the developing radular sac. These expression patterns in Haliotis, a spiralian lophotrochozoan, are similar to POU Class III genes in other bilaterians where expression occurs in secretory cells and the developing nervous system.
