Microinjection of DNA into Aiptasia zygotes. (A) Schematic of injected plasmids: the promoter of an Aiptasia actin gene drives expression of the NLS-eGFP-V2A-mCherry-CaaX reporter with a SV40 termination sequence. Meganuclease I-SceI recognition sites are indicated. (B) The promoter of actin gene XM_021049442.1 drives reporter expression in the majority of larvae coinjected with plasmid and the meganuclease I-SceI. For each promoter tested, the expression level (FPKM) (larvae transcriptomes19), the number of larvae injected and analyzed, and the percentage of larvae in which GFP signal could be detected are given. (C) Coinjection of I-SceI and the prom XM_021049442.1: NLS-eGFP-V2A-mCherry-CAAX:SV40 plasmid causes strong, mosaic expression of the transgene, labeling nuclei (green) and membranes (magenta). 10 hpf, scale = 25 μm.
