Isolation and characterization of paramecium mutants defective in their response to magnesium.

Genetics - 1 Jul 1994

Preston R R, Kung C

Abstract excerpt

Four mutant strains of Paramecium tetraurelia with a reduced ability to respond behaviorally to Mg2+ have been isolated. Voltage-clamp analyses showed that their Mg2+ insensitivity is associated with a reduced Ca(2+)-dependent Mg2+ current. The four mutants, which have been doubled "eccentric," result from recessive mutations in two unlinked loci, xntA and xntB. Further analysis of xntA1 showed it to be unlinked...
