Screening of an EMS-mutagenized population of Arabidopsis thaliana has revealed a fluoroorotic acid (FOA)-resistant mutant. Genetic analysis has shown that FOA resistance was due to a nuclear recessive gene, for1-1. Assays of key regulatory enzymes of the de novo synthesis and salvage of pyrimidines, and also uptake studies using radiolabelled purines and pyrimidines have revealed that for1-1/for1-1 plants were defective in the uptake of free uracil and uracil-like bases.
