Agrobacterium-mediated transient expression has greatly contributed to research in molecular plant biology but has low efficiency and inconsistency in Arabidopsis thaliana (Arabidopsis). Here, we describe a simple, efficient and fast protocol to make transient gene expression in NahG Arabidopsis plants using Agrobacterium tumefaciens. This protocol has been successfully used to assess protein sub-cellular localization and accumulation, enzyme activity, and protein-protein interaction. In addition, this assay overcomes the use of Nicotiana benthamiana plants as a surrogate system for transient gene expression assays. Finally, the use of this protocol does not require complex inoculation methods or specific growth conditions, and can be used with different Agrobacterium strains with similar results.
