Summary of functional genomic tools available in cnidarians. KO—knockout, KI—knock-in, KD—knockdown by RNA interference. References by taxon: Nematostella vectensis [23, 24, 41], Exaiptasia pallida [15], Acropora millepora (KO) [9], Acropora tenuis (KD) [63], Astrangia poculata (this study), Hydra vulgaris [34], Cladonema pacificum [36], Clytia hemisphaerica (KO) [39, 45], Clytia hemisphaerica (KD) [36], Hydractinia echinata (KO, KD) [14, 18], Hydractinia symbiolongicarpus (KI, KD) [13, 46, 50]. The cladogram was inferred from two studies of overlapping taxa [16, 26]. Silhouettes were downloaded from Phylopic.org, license (CC BY-SA 3.0)
