Strategies for promoting high-efficiency homologous gene replacement have been developed and adopted for many filamentous fungal species. The next generation of analysis requires the ability to manipulate gene expression and to tag genes expressed from their endogenous loci. Here we present a suite of molecular tools that provide versatile solutions for fungal high-throughput functional genomics studies based on locus-specific modification of any target gene. Additionally, case studies illustrate caveats to presumed overexpression constructs. A tunable expression system and different tagging strategies can provide valuable phenotypic information for uncharacterized genes and facilitate the analysis of essential loci, an emerging problem in systematic deletion studies of haploid organisms.
促进高效同源基因置换的策略已被开发并应用于许多丝状真菌物种。下一代分析需要具备操纵基因表达以及标记从其内源位点表达的基因的能力。在此,我们展示了一套分子工具,这些工具基于对任何目标基因的位点特异性修饰,为真菌高通量功能基因组学研究提供了通用的解决方案。此外,案例研究说明了假定的过表达构建体存在的问题。一个可调节的表达系统和不同的标记策略可以为未表征的基因提供有价值的表型信息,并有助于分析必需位点,这是单倍体生物系统缺失研究中一个新出现的问题。
