Expression patterns of the genes encoding TSR domain proteins of the D and E groups in the head region of Hydra oligactis.

Among the 6 genes of the D and E groups, five (A, B, D-F) are strongly expressed in the endodermal cells of the head region. The transcript of XM_002154766 (C) was only detected in the tentacles, and not in the hypostome. Accession numbers were labeled on the lower left of each panel. The domain structures of the genes were shown on the top of the photo panels for each group.
