你的基因需要背景检查吗?遗传背景如何影响突变,基因和进化的分析

Does your gene need a background check? How genetic background impacts the analysis of mutations, genes, and evolution

Chris H. Chandler, Sudarshan Chari, Ian Dworkin

摘要:

遗传分析的前提是表型变异和等位基因变异之间存在因果联系。然而,长期以来一直有文献证明,突变表型不是单一DNA损伤的简单结果,而是由于焦点等位基因与其他基因和环境的相互作用。虽然一个严格的实验方法,专注于个别突变和同基因控制菌株,促进了遗传学和相关领域的惊人进展,一瞥回来表明,一个巨大的复杂性已经从我们目前的等位基因效应的理解被忽略了。有了传统的遗传分析和他们提供的基础知识,我们认为,时间和工具已经成熟,可以回到基因功能的未充分探索的方面,并接受遗传效应的背景依赖性。我们断言,广泛的理解遗传效应和等位基因的演化动力学需要确定突变的结果如何依赖于野生型遗传背景。此外,我们讨论了如何最好地利用遗传背景效应,以扩大遗传研究计划。

英文摘要:

The premise of genetic analysis is that a causal link exists between phenotypic and allelic variation. Yet it has long been documented that mutant phenotypes are not a simple result of a single DNA lesion, but rather are due to interactions of the focal allele with other genes and the environment. Although an experimentally rigorous approach, focusing on individual mutations and isogenic control strains, has facilitated amazing progress within genetics and related fields, a glimpse back suggests that a vast complexity has been omitted from our current understanding of allelic effects. Armed with traditional genetic analyses and the foundational knowledge they have provided, we argue that the time and tools are ripe to return to the under-explored aspects of gene function and embrace the context-dependent nature of genetic effects. We assert that a broad understanding of genetic effects and the evolutionary dynamics of alleles requires identifying how mutational outcomes depend upon the wild-type genetic background. Furthermore, we discuss how best to exploit genetic background effects to broaden genetic research programs.
