Figure 1

In Saccharomyces cerevisiae, all microtubules (MTs) originate from the spindle pole body. Kinetochore MTs are required for chromosome segregation, and interpolar MTs are required for nuclear pole separation. Astral MTs interact with the cell cortex and septin ring at the bud neck to orientate the mitotic spindle across the mother–daughter cell junction.
