DefinitionThe spindle pole body is the microtubule organizing center (MTOC) in fungi, functionally equivalent to the animal cell centrosome. The SPB is responsible for the nucleation and organisation of microtubules. This may include the spindle microtubules required for chromosome segregation in mitosis and meiosis as well as the cytoplasmic interphase microtubules.
