HER1 — Cucumis melo
Summary
MELO3C016238.2 (HER1) on melon chromosome 8 encodes a pyridoxal phosphate-dependent aminotransferase with 4-aminobutyrate:pyruvate transaminase and adenosylmethionine-8-amino-7-oxononanoate transaminase activities. The gene is associated with GABA catabolism and the GABA shunt, beta-alanine breakdown, succinate metabolism, and biotin biosynthesis. It has been linked to fruit development, shoot development, pollen tube adhesion, and adaxial/abaxial axis specification. The encoded protein localises to the plant-type vacuole, Golgi, mitochondria, and cytosol. Associations with agronomic traits include seed length and size, fruit quality, saline-alkali tolerance, drought tolerance, insect herbivory resistance, and self-fertility. The gene is also connected to GABA accumulation, pollen tube guidance and elongation, root and hypocotyl growth, transpiration, and light response. Related genes in other species link the family to salt tolerance and GABA-dependent growth regulation.
