The transcription factors HeBlimp and HeT-brain of an indirectly developing polychaete suggest ancestral endodermal, gastrulation, and sensory cell-type specification roles.

Abstract

The expression of Blimp and T-brain was characterized during embryogenesis of the indirectly developing polychaete Hydroides elegans. The expression of both genes in the vegetal blastomeres of this lophotrochozoan is restricted to the lateral and oral regions of the blastopore. Both transcription factors also have expression patterns consistent with… (More)
