Basal-body-associated macromolecules: a continuing debate.
Controversy over the possibility that centrioles/basal bodies contain nucleic acids has overshadowed results demonstrating other macromolecules in the lumen of these organelles. Glycogen particles, which are known to be present within the lumen of the centriole/basal body of sperm cells, have now been found in basal bodies of protists belonging to three different groups. Here, we extend the debate on a role for RNA in basal body/centriole function and speculate on the origin and the function of centriolar glycogen.
