Abstract

Of the 617 genes from Buchnera aphidicola, the obligate bacterial symbiont of the pea aphid, 23% were differentially expressed in embryos compared to adults. Genes involved in flagellar apparatus and riboflavin synthesis exhibited particularly robust upregulation in embryos, suggesting functional differences between the symbiosis in the adult and embryo insect.

摘要

在豌豆蚜的专性细菌共生体 Buchnera aphidicola 的 617 个基因中,有 23%在胚胎与成虫相比时表现出差异表达。参与鞭毛器和核黄素合成的基因在胚胎中表现出特别强烈的上调,这表明成年和胚胎昆虫共生体之间存在功能差异。
