非洲丽鱼科(Cichlidae)鱼类是一类重要的硬骨鱼类,在水产养殖和科学研究中具有重要意义。一个蓬勃发展的研究团体对东非五大湖的慈鲷辐射特别感兴趣。一个关键的目标是查明表型多样化背后的遗传变异,但缺乏遗传工具,排除了彻底解剖慈鲷相关性状的遗传基础。基因组编辑技术已经在斑马鱼和青鳉等硬骨鱼模型中得到了很好的应用。然而,东非慈鲷等新兴模式生物的情况并非如此,大多数实验室仍然无法获得这些技术,部分原因是知识和专门知识的交流有限。Cichlid Science 2022会议(英国剑桥)首次举办了基因组编辑研讨会,社区讨论了基因组编辑的最新进展,重点是CRISPR/Cas9技术。基于研讨会的结果和讨论,在这篇综述中,我们定义了慈鲷基因组编辑的最新技术,分享资源和协议,并提出了进一步扩展慈鲷基因组编辑工具包的新的可能途径。
African cichlid fishes of the Cichlidae family are a group of teleosts important for aquaculture and research. A thriving research community is particularly interested in the cichlid radiations of the East African Great Lakes. One key goal is to pinpoint genetic variation underlying phenotypic diversification, but the lack of genetic tools has precluded thorough dissection of the genetic basis of relevant traits in cichlids. Genome editing technologies are well established in teleost models like zebrafish and medaka. However, this is not the case for emerging model organisms, such as East African cichlids, where these technologies remain inaccessible to most laboratories, due in part to limited exchange of knowledge and expertise. The Cichlid Science 2022 meeting (Cambridge, UK) hosted for the first time a Genome Editing Workshop, where the community discussed recent advances in genome editing, with an emphasis on CRISPR/Cas9 technologies. Based on the workshop findings and discussions, in this review we define the state-of-the-art of cichlid genome editing, share resources and protocols, and propose new possible avenues to further expand the cichlid genome editing toolkit.
