Abstract excerpt

In Aspergillus nidulans a combination of null mutations in halA, encoding a protein kinase, and sltA, encoding a zinc-finger transcription factor having no yeast homologues, results in an elevated calcium requirement ('calcium auxotrophy') without impairing net calcium uptake. sltA(-) (+/-halA(-)) mutations result in hypertrophy of the vacuolar system. In halA(-)sltA(-) (and sltA(-)) strains, transcript levels...
