Centrioles in flies: the exception to the rule?

Centrioles and basal bodies are MT based structures that present a highly conserved ninefold symmetry. Centrioles can be found at the core of the centrosome where they participate in PCM recruitment and organization, contributing to cytoplasmic MT nucleation. Basal bodies are normally located closely to the plasma membrane where they are responsible for axoneme assembly to form structures such as cilia or flagella. While it is well accepted that these organelles have important roles in cell and tissue organization, their contribution to certain phases of animal development is still not entirely established. Here we review the role of centrosomes and cilia in Drosophila melanogaster and briefly discuss the implications of these findings to other model organisms.
