OfERF106-OfACS2 regulatory module helps accelerate the aging process of Osmanthus fragrans petals.

OfERF106 protein binds to the promoter region of the ethylene biosynthesis gene OfACS2 and activates its expression, thereby accelerating the aging process of Osmanthus fragrans petals. Osmanthus fragrans is a multipurpose ornamental plant that combines landscaping utility, aesthetic appeal, and aromatic fragrance, granting it considerable economic and horticultural value. However, its value is substantially constrained by the short overall flowering period and the brief longevity of individual petals. Th…
