Both groups found that bni1 mutants had defects in spindle positioning, using different approaches. The nucleus did not migrate to the neck efficiently, and the spindle was not aligned along the mother-bud axis, based in part on movies of live cells . The spindle then moved into the neck . These phenotypes are similar ...
