Abstract

The commitment phenomenon exhibited by Ceratocystis ulmi is a manifestation of the requirement for a Ca(II)-calmodulin interaction for mycelial growth. Under otherwise identical conditions, addition of CaCl₂(10 mM) to committed yeasts caused them to germinate, while addition of the calmodulin antagonists chlorpromazine (80 μM), dibucaine (750 μM), or trifluoperazine (60 μM) to committed mycelia caused them to bud.
