Abstract

The efficiency of transient gene expression in plants credibly demonstrated characteristics of gene functions in numerous studies. Two key strategies of transient expression became favorites among researchers: protoplast transfection and agroinfiltration. Each of them, alongside the advantages, has its own constraints. In this work, an easy, rapid, and reliable system for characterization of the signal sequences and determinations of target protein localization in a plant cell is proposed and tested. This system—called the AgI–PrI—implies production of protoplasts from plant tissues after agroinfiltration. Reliability of the proposed system for transient gene expression has been proved using characterized signal sequences in Nicotiana benthamiana cells. The corresponding protocol is less expensive and depends to a lesser degree on the professional skills in the area of protoplast isolation and transfection; furthermore, it may be applicable to other plant species with either available efficient methods of agroinfiltration and protoplast isolation or with the potential for one of the protocols to be supplemented. Thus, the AgI–PrI technique makes it possible to combine the advantages of two widely used methods for the transient gene expression in plants—agroinfiltration and protoplast isolation and transfection—and concurrently avoids their critical points.
