LE — Solanum tuberosum

Summary

StLE (PGSC0003DMG400016516) on potato chromosome 6 encodes a gibberellin 3-beta-dioxygenase (EC 1.14.11.15), a member of the 2-oxoglutarate/Fe(II)-dependent dioxygenase superfamily. In potato, this gene is associated with tuberization and tuber size. It is also associated with gibberellin signaling, responses to red and far-red light, fruit ripening, and the biosynthesis of starch, chlorophyll, ethylene, and coumarin. The encoded protein is predicted to localize to the cytoplasm. Associations from studies where the source species is not recorded link this gene to vegetative growth, plant height, seed dormancy, primary root growth, flowering time, stamen and petal development, and fruit growth. Studies of related genes in other species link the family to seed germination, starch degradation, seed coat formation, and hypocotyl growth, while sequence similarity analyses connect it to traits including harvest index, stem elongation, leaf size, and chlorophyll content.
