Duplicated <i>Pax6</i> Gene Expression During Nervous System Development in the Asexually Reproducing Annelid <i>Nais communis</i>.

ABSTRACT: Pax6 plays a highly conserved role in the formation of the eye, development, and patterning of the nervous system across bilaterians. Nevertheless, there are no studies focusing on the role of Pax6 during asexual reproduction, a developmental trajectory that is widespread among metazoans. The present study represents the first investigation of Pax6 gene expression during agametic propagation in annelids. We identified in the asexually reproducing annelid Nais communis four homologs of Pax6 and examined their developmental patterns by in situ hybridization. To establish a morphological basis for the expression patterns, we used immunohistochemistry and confocal laser scanning microscopy to describe the nervous system architecture of the growing adults and
