Amebae of Naegleria gruberi transform into flagellates whose basal bodies have the typical centriole-like structure. The amebae appear to lack any homologous structure, even during mitosis. Basal bodies are constructed during transformation and, in cells transforming synchronously at 25 degrees C, they are first seen about 10 min before flagella are seen. No structural precursor for these basal bodies has been found. These observations are discussed in the light of hypotheses about the continuity of centrioles.
