Summary
Plant vesicle trafficking is crucial for cellular immunity against pathogens. This review highlights how pathogen-associated molecular patterns trigger receptor endocytosis and exocytosis, essential for plant defense mechanisms.
Area of Science:
- Plant immunity
- Cellular biology
- Vesicle trafficking
Background:
- Plant cellular immunity relies on surface pattern recognition.
- Pathogen-associated molecular patterns (PAMPs) are key triggers.
- Vesicle trafficking plays a critical role in plant defense responses.
Purpose of the Study:
- To review recent findings on vesicle trafficking in plant immunity.
- To discuss ligand-stimulated receptor endocytosis in plant immune receptors.
- To explore the role of SNARE-mediated processes in plant defense.
Main Methods:
- Literature review of current research on plant immunity and vesicle trafficking.
- Discussion of pattern-recognition receptor (PRR) mechanisms, including FLS2 and TLR4.
- Analysis of syntaxin involvement in plant defense, exemplified by PEN1 in Arabidopsis.
Main Results:
- Ligand binding triggers endocytosis of pattern-recognition receptors like FLS2.
- N-ethylmaleimide-sensitive factor adaptor protein receptor (SNARE) proteins, such as PEN1, are involved in defense.
- Pathogen-induced endocytic and exocytic processes must be balanced for host homeostasis.
Conclusions:
- Vesicle trafficking, encompassing both endocytosis and exocytosis, is integral to plant immune responses.
- Pathogens may exploit host vesicle trafficking pathways to manipulate plant immunity.
- Further research is needed to understand pathogen strategies targeting plant vesicle trafficking.

01:38Intralumenal Vesicles and Multivesicular Bodies
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...
01:18Protein Transport to the Inner Chloroplast Membrane
Proteins targeted to the inner chloroplast membrane, or plastid proteins, are transported by two general pathways: the stop-transfer and the re-insertion or post-import pathways. Most plastid proteins carry N-terminal transit sequences and internal import sequences targeting it to the specific chloroplast subcompartment. Proteins targeted by the stop-transfer pathway have internal hydrophobic sequences that inhibit their translocation into the stroma. As a result, these precursors are arrested...
01:45Vesicular Tubular Clusters
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.

01:33Overview of Secretory Vesicles
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

01:12Clathrin Coated Vesicles
Clathrin-coated vesicles use endocytosis to transport receptors and lysosomal hydrolases from the Golgi to the lysosome in the late secretory pathway. Clathrin-mediated endocytosis was the first described endocytic process, and Clathrin-coated vesicles remain one of the most well-studied transport vesicles. The molecular machinery that generates clathrin-coated vesicles comprises over 50 proteins that precisely coordinate vesicle formation. Cell surface receptors concentrated in indented sites...
01:44Introduction to Membrane Traffic
The ER, Golgi apparatus, endosomes, and lysosomes work in tandem to modify, sort, and package proteins and lipids. An integrated membrane trafficking network facilitates the back and forth shuttling of molecules within different organelles in the same cell or across the cell membrane.
The transport of soluble and membrane proteins is mediated by transport vesicles that collect cargo from one cellular compartment and deliver it to another by fusing with the target organelle membrane. The Rab...
