Inhibitor treatment and subcellular localization analysis reveal the contribution of a cytosolic terpene synthase to the substantial release of anti-insect monoterpenes by Sphagneticola trilobata (L.) Pruski.

ABSTRACT:

Introduction

Bird strikes are one of the greatest threats to aviation safety in the worldwide. Sphagneticola trilobata (L.) Pruski has anti-insect effects that may indirectly decrease bird populations, thereby reducing bird strikes. However, it is unclear how S. trilobata exerts its anti-insect effects. Moreover, the mechanism mediating the biosynthesis of its main volatile compounds is unknown.

Objectives

This study was conducted to identify the major anti-insect volatile compounds in S. trilobata and elucidate their biosynthetic mechanisms.

Methods

A continuous sampling method was used to analyze the released volatiles of S. trilobata. Direct feeding or fumigation treatments with the main monoterpenes were followed by the evaluation of anti-insect functions. Evoluti
