10H — Cucumis sativus

Summary

CsCYP82A3 (gene symbol 10H, chromosome 3) encodes a cytochrome P450 with methyltetrahydroprotoberberine 14-hydroxylase activity, iron and heme binding, and oxidoreductase activity acting on paired donors with molecular oxygen. It is associated with isoquinoline alkaloid and nicotine anabolism, unsaturated fatty acid and primary metabolism, nitrate assimilation, phenylpropanoid anabolism, secondary metabolism, systemic acquired and induced resistance, stress response, skotomorphogenesis, cell division, and regulation of organ growth. The gene is linked to plant height and localizes to membranes. Studies of related genes in other species connect the family to additional cytochrome P450 activities, including EC 1.14.14.97, 1.14.14.132, and 1.14.14.189.
