Abstract:
Transient gene expression in plant protoplasts facilitates the analysis of hybrid genes in a fast and reproducible manner. The technique is particularly powerful when studying basic conserved biochemical processes including de novo protein synthesis, modification, assembly, transport, and turnover. Unlike individual plants, protoplast suspensions can be divided into almost identical aliquots, allowing the analysis of independent variables with uncertainties restricted to minor pipetting errors/variations. Using the examples of protein secretion and ER retention, we describe the most advanced working practice of routinely preparing, electroporating, and analyzing Nicotiana benthamiana protoplasts. A single batch of electroporation-competent protoplasts permits up to 30 individual transfections. This is ideal to assess the influence of independent variables, such as point mutations, deletions or fusions, or the influence of a co-expressed effector gene in dose-response studies.

Protein Transport to the Outer Chloroplast Membrane
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
