Abstract

We have developed an optimized protocol for isolating protoplasts from chlorenchyma cells of the single-cell C4 species Bienertia sinuspersici. The isolated protoplasts maintained the integrity of the unique single-cell C4 intracellular compartmentation of organelles as observed in chlorenchyma cells after cell wall digestion. Approximately over 80% of isolated protoplasts expressed the fusion reporter gene following the polyethylene glycol-mediated transfection procedures. Overall, fluorescent protein fusion tagged with various intraorganellular sorting signals validated the potential use of the transient gene expression system in subcellular localization and organelle dynamics studies.
