Characterization of tryptophan synthase alpha subunit mutants of Arabidopsis thaliana.

Molecular & general genetics : MGG - 13 Dec 1996

Radwanski E R, Barczak A J, Last R L

Abstract excerpt

Three mutations in the Arabidopsis thaliana gene encoding the alpha subunit of tryptophan synthase were isolated by selection for resistance to 5-methylanthranilate or 5-fluoroindole, toxic analogs of tryptophan pathway intermediates. Plants homozygous for trp3-1 and trp3-2 are light-conditional tryptophan auxotrophs, while trp3-100 is a more leaky mutant. Genetic complementation crosses demonstrated that the...
