ASMT — Cucumis sativus

Summary

CsASMT (CSA_7G017710) on cucumber chromosome 7 encodes an O-methyltransferase with acetylserotonin O-methyltransferase activity, also annotated with naringenin 7-O-methyltransferase and (R)-reticuline 7-O-methyltransferase activities. The protein contains a SAM-dependent methyltransferase domain and is localised to the cytosol, cytoplasm and nucleus. CsASMT is associated with melatonin anabolism, isoflavonoid anabolism, auxin anabolism, photoprotection, regulation of stomatal closure, leaf senescence, seed germination, circadian rhythm, and response to mannitol and osmotic response. It has been linked to net photosynthetic rate, stem diameter, high light stress tolerance, and melatonin synthesis. Studies of related genes in other species connect the family to drought tolerance, disease resistance, chilling tolerance, thermotolerance, chlorophyll content, and water use efficiency.
