Novel polynucleotides encoding enzymes involved in the metabolism of gamma aminobutyric acid (GABA) in plants, specifically, gamma aminobutyric acid transaminase (GABA-T) and gamma hydroxybutyrate dehydrogenase (GHBDH), are described, as well as the GABA-T and GHBDH proteins they encode, and derived antibodies. The polynucleotides are useful for the screening and isolation of other related genes, the antibodies are useful for identifying and isolating related proteins, and the proteins provide a basis for determining how carbon and nitrogen is metabolized in plants. |
