许多种类的蚜虫的报警信息素由倍半萜(E)- - -法尼烯（E β f）组成，它在受到捕食者或寄生性昆虫的攻击时引起分散。我们在拟南芥植物中高水平表达了从薄荷x piperita中克隆的E β f合成酶基因，以引起纯E β f的释放。这些植物对桃蚜（Myzus persicae）（报警和驱避反应）及其寄生蜂rapaeretiella（捕避反应）的行为产生了强有力的影响。在这里，我们报告了一种植物产生昆虫信息素的转化，并证明了由此产生的排放物在两个营养水平上影响行为反应。
The alarm pheromone for many species of aphids, which causes dispersion in response to attack by predators or parasitoids, consists of the sesquiterpene (E)-beta-farnesene (E beta f). We used high levels of expression in Arabidopsis thaliana plants of an E beta f synthase gene cloned from Mentha x piperita to cause emission of pure E beta f. These plants elicited potent effects on behavior of the aphid Myzus persicae (alarm and repellent responses) and its parasitoid Diaeretiella rapae (an arrestant response). Here, we report the transformation of a plant to produce an insect pheromone and demonstrate that the resulting emission affects behavioral responses at two trophic levels.
