Molecular mechanism on the seasonal change in biosynthetic pathways of rose scent compound in response to the environment

本研究旨在阐明玫瑰香2-苯基乙醇（2 PE）生物合成途径随环境变化的分子机制。通过L-[2 H8]苯丙氨酸（[2 H8]LPhe）对玫瑰花的取食实验和GCMS、LCMS分析，阐明了LPhe合成2 PE（LPhe，PPA，PAld，2 PE）的新途径中涉及两个新的酶AAAT和PPDC。我们还证实了该途径在高温环境条件下积极运作。

The objective of the research is to clarify the molecular mechanism on the seasonal change in biosynthetic pathways of rose scent 2-phenylethanol (2PE) in response to environment. Based on the feeding experiments of L-[2H8]phenylalanin ([2H8]LPhe) to rose flowers and the GCMS, and LCMS analyses, we have clarified that two new enzymes, AAAT and PPDC are involved in the new biosynthetic pathway from LPhe to 2PE (LPhe, PPA, PAld, 2PE). We have also confirmed that the pathway is actively operating under the environmental conditions at high temperature.
