Gonad-specific expression of Terb1, Terb2, and Majin in Hydra vulgaris. a Terb1, Terb2, Majin were detected in Hydra tissues by RT-PCR. Actin was used as a control. All three transcripts are exclusively found in the testes. b Whole mount in situ hybridization to detect HySycp3, HyTerb1, HyTerb2, and HyMajin transcripts. Arrows indicate the regions shown enlarged in the insets. All four transcripts were detected in cells at the base of the testes
