HER1 — Daucus carota subsp. sativus
Summary
DcHER1 (DCAR_029734) on carrot chromosome 9 encodes a pyridoxal phosphate-dependent transaminase with 4-aminobutyrate:pyruvate transaminase activity and adenosylmethionine-8-amino-7-oxononanoate transaminase activity. The gene is associated with GABA catabolism, the GABA shunt, beta-alanine breakdown, succinate metabolism, and biotin anabolism. It has been linked to pollen tube adhesion, fruit development, leaf and shoot development, and adaxial/abaxial axis specification. The encoded protein localises to the cytosol, mitochondria, Golgi complex, and plant-type vacuole. Phenotypic associations include GABA accumulation, fruit quality, saline-alkali tolerance, drought tolerance, insect herbivory resistance, self-fertility, and responses to light and E-2-hexenal. Related genes in other species are linked to salt tolerance, pollen tube growth defects, and root growth inhibition upon GABA exposure.
