A fluoroorotic acid (FOA)-resistant mutant of Arabidopsis thaliana was isolated by screening M2 populations of ethyl methane sulphonate (EMS)-mutagenized Columbia seed. FOA resistance was due to a nuclear recessive gene, for1-1, which locates to a 519 kb region in chromosome 5. Assays of key regulatory enzymes in de novo pyrimidine synthesis (uridine(More)
The solute specificity profiles (transport and binding) for the nucleobase cation symporter 1 (NCS1) proteins, from the closely related C4 grasses Zea mays and Setaria viridis, differ from that of Arabidopsis thaliana and Chlamydomonas reinhardtii NCS1. Solute specificity profiles for NCS1 from Z. mays (ZmNCS1) and S. viridis (SvNCS1) were determined(More)
