This research investigates the impact of various factors on the efficiency of Agrobacterium-mediated transient gene expression in plants.
Used two A. tumefaciens strains, LBA4404 and EHA105, with a GFP reporter gene.
Applied vacuum infiltration at different pressures and times.
Measured GFP expression in N. benthamiana leaves post infiltration at varying Agrobacterium concentrations.
Assessed the effect of incubation time on GFP intensity.
Increasing vacuum pressure enhanced GFP expression, peaking at 0.07 MPa.
Longer vacuum infiltration time (20 min) significantly boosted GFP levels.
Optimal Agrobacterium concentrations were OD600 0.5 for LBA4404 and OD600 0.3 for EHA105.
Incubation time of 4 days maximized GFP expression, while 6 days led to a reduction.
