AAT2 — Cucumis melo

Summary

MELO3C003577.2 (symbol AAT2, also known as CmAAT2 and YLS4) on melon chromosome 5 encodes an aspartate aminotransferase (EC 2.6.1.1) with L-aspartate:2-oxoglutarate transaminase activity, pyridoxal phosphate binding, copper binding, and ATP hydrolase activity. The gene is associated with amino acid metabolism, the TCA cycle, 2-oxoglutarate and glutamate metabolism, and the CRISPR-Cas system. It is linked to meristem growth and structural organization, root cap development, root morphogenesis, phyllome and inflorescence development, and male and female gamete generation. Associations with traits include zinc and herbicide sensitivity, disease tolerance, leaf composition, and organ identity. Phenotypic connections include leaf senescence, disease resistance to Botrytis cinerea, reduced root growth with decreased phloem aspartate transport, and UV-B sensitivity. The protein localizes to mitochondria, the cytosol, plastids, the plant-type cell wall, and the proteasome.
