Simplified Protocol to Demonstrate Gene Expression in Nicotiana benthamiana Using an Agrobacterium-Mediated Transient Assay
Agrobacterium-mediated transient gene expression in Nicotiana benthamiana is widely used to study gene function in plants. One dramatic phenotype that is frequently screened for is cell death. Here, we present a simplified protocol for Agrobacterium-mediated transient gene expression by infiltration. Compared with current methods, the novel protocol can be done without a centrifuge or spectrometer, thereby suitable for K-12 outreach programs as well as rapidly identifying genes that induce cell death. Key features • The protocol simplifies the widely used Agrobacterium-mediated transient gene expression assay [1] and can be completed within one week when plants are available. • Rice XB3 gene can induce a dramatic and easily identifiable cell death phenotype in Nicotiana benthamiana. • Allows identification of cell death–inducing genes and is suitable for teaching. • Compared to the currently used methods, our protocol omits the use of agroinfiltration buffer, pH meter, temperature-controlled growth chamber, centrifuge, and spectrophotometer.
