基因工程一篇Science文章。求翻譯摘要。Genetic Engineering

隔行如隔山啊 求翻譯下面摘要。當然 如果您看過這篇文獻 幫忙介紹一下文章主要研究內(nèi)容再好不過了 特此感謝 感謝 可追加金幣的。Herbivore-damaged plants release complex mixtures of volatiles that attract natural enemies of the herbivore. To study the relevance of individual com- ponents of these mixtures for predator attraction, we manipulated herbivory- induced volatiles through genetic engineering. Metabolic engineering of terpenoids, which dominate the composition of many induced plant volatile bouquets, holds particular promise. By switching the subcellular localization of the introduced sesquiterpene synthase to the mitochondria, we obtained transgenic Arabidopsis thaliana plants emitting two new isoprenoids. These altered plants attracted carnivorous predatory mites (Phytoseiulus persimilis) that aid the plants’ defense mechanisms. |

金蟲 (小有名氣)

| 受植食性昆蟲為害的植物會釋放可吸引該植食性昆蟲的天敵的復(fù)雜揮發(fā)性物質(zhì)。為研究這些混合物中對天敵起引誘作用的各單一組分之間的相互關(guān)系,我們通過轉(zhuǎn)基因技術(shù)來改變蟲害誘導(dǎo)的揮發(fā)物。作為誘導(dǎo)性植物揮發(fā)物的主要成分——萜類物質(zhì),對其進行代謝工程方面的研究很有前景。通過將插入的倍半萜合酶進行亞細胞定位至線粒體,我們獲得了可釋放兩種新異戊間二烯化合物的轉(zhuǎn)基因擬南芥。這些轉(zhuǎn)基因植株可吸引對植物防御機制有幫助的捕食性螨(智利小植綏螨)。 |
