CYP82G1 Enzyme Functions as Chromone Hydroxylase in the Biosynthesis of 6-Hydroxy-2-(2-Phenylethyl)chromone in Aquilaria sinensis. [PDF]

open access: yesPlant Biotechnol J
ABSTRACT Aquilaria sinensis, a plant of the genus Aquilaria in the family Thymelaeaceae, can form resinous and fragrant agarwood in response to wounding or infection. The resin physically occludes xylem vessels and ray parenchyma, limiting pathogen mobility and resource loss.
