main product is beta-phellandrene. The profile of monoterpenes produced by PHS1 is identical with the monoterpenes found in type VI glandular trichome. In tomato glands, neryl diphosphate serves as a precursor for the synthesis of monoterpenes

neryl diphosphate most likely ionizes to a neryl cation, which can further isomerize to an alpha-terpinyl cation. Further transformations of this cyclic intermediate can eventually yield all observed products of PHS1
the main product is beta-phellandrene
