[Effects of alpha-amanitin on the development of Xenopus (Xenopus laevis Daud.) heart in vitro].
The differentiation of Xenopus heart is studied in vitro, in the presence of alpha-amanitin. The results obtained depend on the concentration of the inhibitor, the length of treatment and the stage of primordium. The mRNA pool assures the differentiation of explants, removed from young stages, for 12 hours. This time is half for the primordia removed from stages greater than 3,5 mm.
