LE — Medicago truncatula

Summary

MTR_2G102570, also known as LE or MtGA4, encodes a gibberellin 3-beta-dioxygenase, a member of the 2-oxoglutarate-dependent dioxygenase family. This gene is associated with gibberellin signaling and response, as well as responses to red or far-red light, light stimulus, cold acclimation, and molecules of fungal origin. It is linked to the biosynthesis of morphine, isoflavonoids, coumarins, and flavonoids. It has been connected to somatic embryogenesis and embryogenesis. Associations with agronomically relevant traits include petiole length, leaf shape and size, chlorophyll content, plant height, vegetative growth, seed dormancy, primary root growth, hypocotyl elongation, flowering time, fruit growth, and petal and stamen development. Studies of related genes in other species link the family to gibberellin biosynthesis, reduced bioactive GA4 levels, and seed coat development.
