ASMT — Cucumis sativus

Summary

CsASMT (CSA_7G017720) on cucumber chromosome 7 encodes an O-methyltransferase domain-containing protein. The gene is associated with acetylserotonin O-methyltransferase activity, apigenin 4'-O-methyltransferase activity, naringenin 7-O-methyltransferase activity, (R)-reticuline 7-O-methyltransferase activity, kaempferol 4'-O-methyltransferase activity, O-methyltransferase activity, SAM-dependent methyltransferase activity, protein dimerization activity, and identical protein binding. It is linked to melatonin anabolism, auxin anabolism, chlorophyll anabolism, alkaloid anabolism, photoprotection, circadian rhythm, leaf senescence, seed germination, downregulation of seed germination, regulation of stomatal closure, defence response to fungi, cell death, regeneration, response to mannitol, osmotic response, and homeostasis. It localises to the cytosol, cytoplasm, and nucleus. The gene is associated with stem diameter, net photosynthetic rate, photosynthetic rate, melatonin synthesis, and high light stress tolerance. Related genes in other species link the family to drought sensitivity, water use efficiency, chlorophyll content, seed dormancy, oxidative stress response, and chilling tolerance.
