Hydrogen peroxide, an important signal inducing vessel occlusions and stimulating sesquiterpene accumulation in stems of Aquilaria sinensis
Agarwood is highly valuable resinous and fragrant heartwood produced principally from tropical trees in the genus Aquilaria,which is used widely in countries of Middle East,Southeast Asia and Japan.Generally,healthy tree will not produce agarwood,but wounding of Aquilaria tree could initiate the production of argarwood.In this study,the pruning of actively growing saplings of A.sinensis resulted in hydrogen peroxide (H2O2) burst,which was followed by a stimulation of vessel occlusions formation and sesquiterpenes biosynthesis in pruned stems.However,treatment of the pruned stems with H2O2 inhibitors,ascorbate (AsA) greatly reduced the amount of H2O2,and greatly reduced the number of vessel occlusions and the amount of sesquiterpenes.
