摘要

微生物组被假设为宿主生物表型变异的驱动力,能够延长代谢过程,改变发育,在某些情况下,赋予对生存至关重要的新功能。只有少数研究直接表明环境微生物组在改变宿主表型特征中的因果作用。为了评估环境微生物诱导宿主生活史性状和行为变化的程度,我们用从两个不同地点收集的果蝇种群中分离的微生物接种了无菌黑腹果蝇,并产生了两个具有不同细菌和真菌特征的种群。我们表明,从具有适度非生物差异的环境中分离出来的微生物会引起宿主繁殖、脂肪酸水平、应激耐受性和睡眠行为的巨大变化。重要的是,从每个实验群体中清除微生物消除了表型差异。这些结果支持了环境微生物作为宿主表型可塑性和潜在的快速适应和进化驱动因素的因果作用。

Environmental microbes promote phenotypic plasticity in reproduction and sleep behaviour

The microbiome has been hypothesized as a driving force of phenotypic variation in host organisms that is capable of extending metabolic processes, altering development and in some cases, conferring novel functions that are critical for survival. Only a few studies have directly shown a causal role for the environmental microbiome in altering host phenotypic features. To assess the extent to which environmental microbes induce variation in host life-history traits and behaviour, we inoculated axenic Drosophila melanogaster with microbes isolated from drosophilid populations collected from two different field sites and generated two populations with distinct bacterial and fungal profiles. We show that microbes isolated from environmental sites with modest abiotic differences induce large variation in host reproduction, fatty acid levels, stress tolerance and sleep behaviour. Importantly, clearing microbes from each experimental population removed the phenotypic differences. The results support the causal role of environmental microbes as drivers of host phenotypic plasticity and potentially, rapid adaptation and evolution.

期刊介绍: Molecular Ecology publishes papers that utilize molecular genetic techniques to address consequential questions in ecology, evolution, behaviour and conservation. Studies may employ neutral markers for inference about ecological and evolutionary processes or examine ecologically important genes and their products directly. We discourage papers that are primarily descriptive and are relevant only to the taxon being studied. Papers reporting on molecular marker development, molecular diagnostics, barcoding, or DNA taxonomy, or technical methods should be re-directed to our sister journal, Molecular Ecology Resources. Likewise, papers with a strongly applied focus should be submitted to Evolutionary Applications. Research areas of interest to Molecular Ecology include: * population structure and phylogeography * reproductive strategies * relatedness and kin selection * sex allocation * population genetic theory * analytical methods development * conservation genetics * speciation genetics * microbial biodiversity * evolutionary dynamics of QTLs * ecological interactions * molecular adaptation and environmental genomics * impact of genetically modified organisms
