Background:

• Fluorescent proteins (FPs) are crucial tools in plant science.
• Their primary use is as reporter proteins to track protein localization within plant cells.
• Understanding subcellular localization is key to deciphering protein function.

Purpose of the Study:

• To describe methods for transiently expressing fluorescent protein-interest fusion constructs in plant cells.
• To provide versatile techniques applicable across different plant species.
• To facilitate diverse applications of fluorescent proteins in plant research.

Main Methods:

• Particle bombardment for introducing foreign DNA into plant cells.
• Protoplast transformation for delivering genetic material into plant cells lacking cell walls.
• Agrobacterium-mediated infiltration for transient gene expression in plant tissues.

Main Results:

• Successful transient expression of fluorescent protein-protein of interest (FP-POI) fusion constructs.
• Demonstration of versatility across different plant species and cell types.
• Validation of the described methods for reporter protein applications.

Conclusions:

• The described methods offer robust approaches for transient expression of FP-POI fusions in plants.
