Erigeron 属植物が特異的に生成するプロピレン

抄録

We detected endogenous propylene as a peculiarity of the genus Erigeron plants during the analysis of physiological properties of ethylene among plant species and their cultivars. The unknown peak with about 5.8 min. retention time in our GC system in Erigeron plants was identified as propylene by GC-MS. Propylene was determined in the leaf (and callus) of E.philadelficus, E.annuus , E.canadensis, Conyza sumatrensis(E.fioribundus). We could not find it in other species including some Compositae plants. Propylene production fluctuated by light/dark condition and it was remarkably promoted in light. This behavior is very different from that of ethylene which is produced in the darkness much more than in light.
