Live imaging of transgenic Hydractinia gastrozooids. a A polyp expressing eGFP under an RFamide precursor promoter, labeling a subset of neurons. The animal was created via random integration of a circular DNA plasmid. b A polyp expressing eGFP under the endogenous Eef1a promoter. The animal was created using CRISPR/Cas9 to target integration of the eGFP coding sequence into the Hydractinia Eef1a locus
