Abstract
Plant transformation and exogenous protein expression is essential for molecular biology and biotechnology. Current approaches of stable plant transformation might be problematic and very time-consuming. Because of this, transient expression in protoplasts has become valuable alternative, being less cost and time-effective at the same time. Excellent for eukaryotic proteins, representing a natural cell habitat, protoplast isolation is widely used in protein interaction visualization techniques, like BiFC (Bimolecular fluorescence complementation) and FRET (Förster resonance energy transfer). In this protocol we present a another use of Arabidopsis protoplast in protein degradation assay, proving its high versatility as a tool in proteomics.
