Hydra magnipapillata
In Hydra magnipapillata the activator of protein kinase C diC8 causes multiple head formation along the body axis only when accompanied by feeding, but heavy feeding alone is sufficient to cause multiple head formation
... Here we show that diC8 by itself is unable to induce the formation of ectopic heads in Hydra magnipapillata. DiC8 can only induce such structures when combined with feeding. In addition, heavy feeding alone ...
