Short summary

MEK is an important VOC in atmospheric chemistry and recently it has been shown that biogenic sources are globally as important as anthropogenic ones. We unveiled the mechanism by which within-plant transformation of MVK is a source of biogenic MEK. Such transformation is observed in red oak for both exogenous MVK, taken up from the atmosphere, and endogenous MVK generated within plant when it experiences stress (e.g. heat stress). The new mechanism is important for inclusion in models.
