ABSTRACT
Amphioxus Bblhx3 was identified as a LIM-homeobox gene expressed in gastrulae. Structural analysis suggested that it is a member of lhx3 but not of lhx1 gene group. Whole mount in situ hybridization revealed that expression of Bblhx3 was initiated at the early gastrula stage and continued at least until 10-day larvae. Expression of Bblhx3 first appeared in the vegetal and future dorsal area in initial gastrulae and became restricted to the endoderm during gastrulation. In neurulae and early larvae, Bblhx3 was expressed in the developing neural tube, the notochord and preoral pit lineage. In 10-day larvae, Bblhx3 was expressed only in the preoral pit. This expression pattern is apparently distinct from that of vertebrate lhx3 genes that are not expressed during gastrulation.
