Metabolic Signatures of Aging and Gametogenesis in Hydra oligactis
Aging can be experimentally induced in Hydra oligactis, making it an exception among the “immortal” cnidarian genus Hydra. In response to cold temperatures, H. oligactis polyps switch from asexual to “emergency” sexual reproduction and eventually age and die. We used GC–MS‐based metabolite profiling to characterize col...
