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(More)
In this paper we are concerned with the inverse spectral problems for energy-dependent Sturm-Liouville problems (that is, differential pencils) defined on interval [0, 1] with two potentials known on a subinterval [a 1 , a 2 ] ⊂ [0, 1]. We prove that the potentials on the entire interval [0, 1] and the boundary condition at x = 1 are uniquely determined in(More)
