Sammanfattning

We identify an Arabidopsis pyridoxal-phosphate-dependent aminotransferase, VAS1, whose loss-of-function simultaneously increases amounts of the phytohormone auxin and the ethylene precursor 1-aminocyclopropane-1-carboxylate. VAS1 uses the ethylene biosynthetic intermediate methionine as an amino donor and the auxin biosynthetic intermediate indole-3-pyruvic acid as an amino acceptor to produce L-tryptophan and 2-oxo-4-methylthiobutyric acid. Our data indicate that VAS1 serves key roles in coordinating the amounts of these two vital hormones.
