AUR3 — Cucumis melo

Summary

MELO3C013566.2, also known as CmAUR3, encodes a GH3 family protein with GH3_M and GH3_C domains and exhibits multiple amino acid synthetase activities, including IAA amido synthetase, jasmonate-amino synthetase, and 4-hydroxybenzoate amino acid synthetase activity. In melon, this gene is associated with auxin conjugate metabolism, benzoate metabolism, chorismate metabolism, camalexin anabolism, and regulation of systemic acquired resistance. It is linked to detection of fungi, regulation of defence response to bacteria, cellular auxin homeostasis, and salicylic acid-mediated signaling. Associations with traits include stem angle, ethylene sensitivity, root morphology, and disease resistance. The gene product localises to the chloroplast envelope, stroma, plasmodesmata, mitochondria, cytosol, plasma membrane, and nucleus. Studies of related genes in other species connect the family to auxin and salicylic acid homeostasis, pathogen defence, root architecture, and abiotic stress tolerance.
