GAL1 — Cucumis melo

Summary

MELO3C006726.2 (symbol GAL1, also known as CmGAL1) on melon chromosome 7 encodes a galactokinase, an enzyme that phosphorylates galactose and belongs to the GHMP kinase family. The gene is associated with galactose metabolism, carbohydrate phosphorylation, and sucrose metabolism, as well as with fruit development and ripening. It has been linked to fruit firmness, sugar content, sucrose content, and respiration rate. Additional associations include protein binding, protein deneddylation, COP9 signalosome assembly, signal transduction, and diterpenoid anabolism. The encoded protein localises to the cytosol and cytoplasm. Studies of the related Arabidopsis gene CSN7 link the family to photomorphogenesis, anthocyanin accumulation, and UV tolerance.
