pubmed:abstractText |
In Aspergillus nidulans the temperature-sensitive cell cycle mutation bimE7 causes chromosome condensation and pre-anaphase spindle formation to occur at restrictive temperature. By constructing double mutants between bimE7 and S phase or G2 phase mutants and blocking DNA replication with hydroxyurea, we demonstrate that bimE7 can cause chromatin condensation and spindle formation in cells held in S or G2. Thus bimE7 overrides normal control systems that prevent mitosis from prematurely occurring during S or G2. We show that bimE7 is a loss of function mutation and propose that bimE normally functions to negatively control a positive mitotic inducing factor, possibly the cell cycle gene nimA.
