Description

Xueqian Gao and co-authors find the enzymes behind an orchid's scent in a 2025 study. The orchid Cymbidium sinense is prized for its strong fragrance, and one sweet compound, dihydro-β-ionone, carries much of it.

That compound grew more abundant as flowers opened and came mostly from sepals and petals. Gene scans across three flower stages found four candidate reductase genes. Their activity peaked in the same tissues and rose in step with the scent compound. Three of the four enzymes, made in bacteria, converted the parent compound into the scent in a dish, and leaf tests in a tobacco relative confirmed the work in living tissue. Two enzymes also acted on other scent related compounds.
