Tryptophan mutants in Arabidopsis: the consequences of duplicated tryptophan synthase beta genes.

The Plant cell - 1 Apr 1991

Last R L, Bissinger P H, Mahoney D J, Radwanski E R, Fink G R

Abstract excerpt

The cruciferous plant Arabidopsis thaliana has two closely related, nonallelic tryptophan synthase beta genes (TSB1 and TSB2), each containing four introns and a chloroplast leader sequence. Both genes are transcribed, although TSB1 produces greater than 90% of tryptophan synthase beta mRNA in leaf tissue. A tryptophan-requiring mutant, trp2-1, has been identified that has about 10% of the wild-type tryptophan...
