白色念珠菌是一种机会性真菌病原体,可导致重大疾病和死亡。在缺乏完全交配和其他方便方法的情况下,对其毒力因子的剖析依赖于强大的工具来删除、补充或以其他方式修改这种二倍体生物体中的相关基因。在这里,我们描述了从PCR盒瞬时表达的Cas9和sgRNAs的设计原理和用途,以修饰感兴趣的基因,在单个转化步骤中产生纯合子突变。
Candida albicans is an opportunistic fungal pathogen responsible for significant disease and mortality. Absent complete mating and other convenient methods, dissection of its virulence factors relies on robust tools to delete, complement, and otherwise modify genes of interest in this diploid organism. Here we describe the design principles and use of Cas9 and sgRNAs transiently expressed from PCR cassettes to modify genes of interest, generating homozygous mutants in a single transformation step.
