Expression patterns of the top five genes encoding TSR domain proteins in Hydra oligactis.

(A) A schematic drawing of a longitudinal cross section of an adult hydra. (B-F) Expression patterns of the top five genes encoding TSR domain proteins in Hydra oligactis by whole mount in situ hybridization. All the genes are expressed in the head region. The accession numbers of the genes were shown on the lower left in each panel.
