Description
Hao Ding and co-authors trace the genetics behind the sweet scent of aromatic coconuts, in a 2026 study. The scent comes mainly from a compound called 2AP, prized in breeding but poorly understood at the gene level. The team built populations that contrast scented and plain coconuts and attacked the question from several angles at once.
They measured enzyme activity, tracked the flow of raw materials, scanned population-wide gene variation, and mapped gene control networks. The amino acid glutamate and its products stood out as tightly tied to scent strength. One enzyme in that pathway, P5CS, showed signs of strong purifying selection, and one form of its gene dominated in scented trees. A switch gene that turns it on was also found. The team built scent markers from the pathway's inputs and outputs to grade young trees early.
