THE MIGRATION OF FUNGAL NUCLEI IN AN ELECTRIC FIELD

The mycelium of Neurospora tetrasperma readily conducts an electric current. During the time an electric current of about 5 μa. is allowed to pass through cultures of N. tetrasperma or Gelasinospora tetrasperma, mycelial growth ceases almost entirely, but afterwards the fungi grow normally again and show no ill effects. Electric currents of the order of 1 or 10 μa. running in either direction through two fused strains of N. tetrasperma do not alter the normal direction of nuclear migration from one strain to the other.
