Engineering and implementation of synthetic molecular tools in the basidiomycete fungus Ustilago maydis
biorxiv(2023)
摘要
The basidiomycete Ustilago maydis is a well-characterized model organism for studying pathogen-host interactions and of great interest for a broad spectrum of biotechnological applications. To facilitate research and enable applications, in this study, three luminescence-based and one enzymatic quantitative reporter were implemented and characterized. We generated dual-reporter constructs for ratiometric normalization that can be used as a fast-screening platform for reporter gene expression, applicable to in vitro and in vivo detection. Furthermore, we constructed and implemented synthetic bi-directional promoters, that enable bicisitronic expression for gene expression studies and engineering strategies. These non-invasive, quantitative reporters and expression tools will widen significantly the application range of biotechnology in U. maydis and enable in planta detection of fungal infection.
