Locus-dependent profiles of the rescue of nonexcitable behavioral mutants during conjugation in Tetrahymena thermophila.

Abstract

The Tetrahymena nonreversal (TNR) mutants of Tetrahymena thermophila are behavioral mutants with nonexcitable membranes. When cells of the tnrB mutant were mated with wild type, a phenotypic change occurred about 1 h after pair formation. The pairs began to lose their heterotypic character in stimulation solution containing high potassium and, within 1 1/2… (More)
