模式生物对于理解基础生物学和推动生物医学研究具有重要意义。然而,实验室培养对这些生物的影响没有得到充分重视,特别是环境如何影响研究结果。最近的实验使人们深入了解了广泛使用的秀丽隐杆线虫实验室参考菌株与自然菌株的比较情况。在这里,我们描述了潜在的选择压力,导致固定的基因npr-1,glb-5和nath-10的实验室衍生的等位基因。这些等位基因影响大量的性状,导致影响实验解释的行为。此外,由这些实验室衍生的等位基因引起的强表型效应阻碍了天然等位基因的发现。我们强调减少实验室来源的等位基因的影响和利用C的全部力量的策略。优雅的。
Model organisms are of great importance to understanding basic biology and to making advances in biomedical research. However, the influence of laboratory cultivation on these organisms is underappreciated, especially how that environment can affect research outcomes. Recent experiments led to insights into how the widely used laboratory reference strain of the nematode Caenorhabditis elegans compares to natural strains. Here, we describe potential selective pressures that led to fixation of laboratory-derived alleles for the genes npr-1, glb-5, and nath-10. These alleles influence a large number of traits, resulting in behaviors that affect experimental interpretations. Furthermore, strong phenotypic effects caused by these laboratory-derived alleles hinder the discovery of natural alleles. We highlight strategies to reduce the influences of laboratory-derived alleles and to harness the full power of C. elegans.
