Direct gene transfer methods. The trem Direct gene transfer is used to discriminate between the methods of plant transformation that rely on Agrobacterium (indirect method) and those that do not (direct methods). Direct gene transfer methods all rely on the delivery of large amount of naked DNA whilst plant is transiently permeabilised.
