摘要Shells are one of the most notable features of the majority of mollusks. In addition, the shell is also considered a key characteristic during molluscan evolution and development. However, although the morphological changes during larval shell formation have been well described, the underlying molecular mechanisms remain poorly understood. In this study, we focused on the potential involvement of a GATA gene in shell formation because GATA genes are often downstream genes of BMP (bone morphogenetic protein) signaling pathways, which have been suggested to participate in molluscan shell formation. In the Pacific oyster Crassostrea gigas, we observed that the expression of a GATA2/3 homolog (cgi-gata2/3) was clearly restricted to the edge of the shell field in early larval stages (trochophore and D-veliger). This expression pattern supports the notion that cgi-gata2/3 gene plays conserved roles in bilaterian ectodermal development. It is possible that cgi-gata2/3 is one shell-formation gene under the regulation of BMP signaling pathways. In addition, cgi-gata2/3 was also detected in the ventral side of embryos. The expression of cgi-gata2/3 away from the shell field may be involved in hematopoiesis. Our results provide fundamental support for studies into the molecular mechanisms of larval shell formation and the functions of molluscan GATA genes.
