GA2OX1 — Solanum tuberosum

Summary

PGSC0003DMG400021095, designated GA2OX1 on potato chromosome 2, encodes a 2-oxoglutarate-dependent dioxygenase with domains including DIOX_N and Oxoglu/Fe-dep_dioxygenase. It is annotated with gibberellin 2-oxidase activity, gibberellin 3-beta-dioxygenase activity, (S)-tetrahydroprotoberberine N-methyltransferase activity, 2-oxoglutarate dioxygenase activity, vitamin C binding, and metal binding. In potato, GA2OX1 is associated with tuberization, tuber formation, gibberellic acid metabolism, and tolerance to low temperature, drought, and salt stress. The gene is linked to responses to red and far-red light, hypoxia, fungal infection, and processes including seed germination, root development, secondary growth, and the mevalonate pathway. Associations also include relative chlorophyll and nitrogen content, photosynthetic rate, stomatal resistance, plant height, lateral branching, hypocotyl elongation, shade avoidance suppression, anthocyanin accumulation, and resistance to Phytophthora infestans. Studies of related genes in other species connect the family to fruit development, ripening, parthenocarpy, seed development, chilling tolerance, and root elongation.
