TargetedGeneReplacementinFungiUsingaSplitMarkerApproach

Targeted gene replacement is one of the primary strategies for functional characterization of fungal genes and several methods have been developed for this purpose over the years. The increased availability of genome sequence information in the present times has enabled wider adoption of protocols based on the knowledge of the gene sequence and its surrounding region. Among such targeted gene replacement ......阅读全文
