[Effect of actinomycin D on transformation of the planulae of Obelia loveni (Allman)].
The incubation of planulae Obelia loveni in the actinomycin D solution (40 mug/ml) for 3 hrs at 17--20 degrees resulted in the marked inhibition of the process of attachment of planulae to the substrate and their transformation in polyps. A suggestion is put forward that at the final phase of larval development a special RNA is synthesized which participates in the genetically determined control of the complicated morphogenetic phenomenon of attachment and transformation of the planula in polyp.
