Identification of an Arabidopsis thaliana mutant accumulating threonine resulting from mutation in a new dihydrodipicolinate synthase gene

Summary A novel Arabidopsis DHDPS gene named DHDPS2 was found through identification of a mutant by promoter trapping. The mutation promotes a reduction of growth resulting from combination of a defect in lysine biosynthesis and accumulation of a toxic level of threonine or derived products. The mut...
