HER1 — Cucumis melo
Summary
MELO3C032583.2, designated HER1 (also known as CmVAMT, CmGABA-TP1-3, and CmPOP2) on melon chromosome 8, encodes a pyridoxal phosphate-dependent transaminase with 4-aminobutyrate:pyruvate transaminase and adenosylmethionine-8-amino-7-oxononanoate transaminase activities. The gene is associated with GABA catabolism, the GABA shunt, beta-alanine breakdown, succinate metabolism, and biotin biosynthesis. It is linked to fruit development, shoot development, pollen tube adhesion, adaxial/abaxial axis specification, and response to alcohol. Associations with agronomic traits include seed length and size, fruit quality, saline-alkali tolerance, drought tolerance, insect herbivory resistance, and self-fertility. The encoded protein localizes to the plant-type vacuole, Golgi complex, mitochondria, and cytosol. Studies of related genes in other species link the family to fruit ripening, salt tolerance, and herbivore defense.
