FIG. 4.

Chromatin organization of the amdS::lacZ fusion gene in a CCAAT and hapE mutant strain. MH1 corresponds to the wild-type strain. In strain MH9206, hapE is deleted. In strain MH5733, the CCAAT motif is mutated to CAGAT (Fig. 2). Mycelia were grown for 16 h on 1% glucose plus 10 mM ammonium tartrate. Chromatin analysis was performed as indicated in the legend of Fig. 1B. Nucleosomes are pictured at the right as ellipses. The dashed ellipses indicate a less strict positioning of nucleosomes. The vertical map at the left indicates the relative positions of TATA box, CCAAT sequence, and amdS::lacZ coding region.
