CRISPR是一种越来越多地用于实验室基础研究和应用研究的技术。我们为本科生设计并实现了一个实验室体验,在实验室中进行CRISPR技术,敲除翅膀图案基因optixand wntainvanessa carduibutterflies。学生们获得了蝴蝶翅膀颜色和图案的惊人表型突变,唤起了他们对基因组如何编码形态的好奇心。此外,学生们成功地使用分子技术对野生型毛毛虫幼虫和蝴蝶进行基因分型和筛选,以便对基因进行CRISPR编辑。学生的反馈表明,通过执行整个CRISPR工作流程,从CRISPR组件的设计和交付到蝴蝶卵的显微注射,到活体动物的整个生命周期的饲养,以及由此产生的突变体的分子和表型分析,他们经历了一个有意义的科学探究过程。我们讨论了我们在蝴蝶中使用CRISP基因组编辑实验的经验,让学生接触到在一个有魅力的活生物体中探索基因与表型关系的实践研究经验。
CRISPR is a technique increasingly used in the laboratory for both fundamental and applied research. We designed and implemented a lab experience for undergraduates to carry out CRISPR technology in the lab, and knockout the wing patterning genesoptixandWntAinVanessa carduibutterflies. Students obtained spectacular phenotypic mutants of butterfly wings color and patterns, awakening curiosity about how genomes encode morphology. In addition, students successfully used molecular techniques to genotype and screen wild‐type caterpillar larvae and butterflies for CRISPR edits in genes. Student feedback suggests that they experienced a meaningful process of scientific inquiry by carrying out the whole CRISPR workflow process, from the design and delivery of CRISPR components through microinjection of butterfly eggs, the rearing of live animals through their complete life cycle, and molecular and phenotypic analyses of the resulting mutants. We discuss our experience using CRISP genome editing experiments in butterflies to expose students to hands‐on research experiences probing gene‐to‐phenotype relationships in a charismatic and live organism.
