confocal microscopy analysis of protein sorting to plasmodesmata in nicotiana benthamiana

Plasmodesmata (PD) play a fundamental role in controlling plant development, environmental responses, and interactions with viral pathogens through the regulation of intercellular communication1,2. PD initially forms during cytokinesis, with hundreds of PD inserted into the new cell between the two daughter cells, thus supplying the channels for cell-to-cell communication3,4. PD is a membrane-rich structure, containing the endoplasmic reticulum (ER)-derived membrane, a trans-PD desmotubule, in the central part of the pores that are lined by the plasma membrane3,4. Comparative proteomic approaches identified numerous PD functional proteins, including &#946;-1,3-glucanases (BGs), callose synthases (CALSs), plasmodesmata-located proteins (PDLPs), callose-binding proteins (PDCBs), multiple C2 domains transmembrane region proteins (MCTPs)3, and leucine-rich repeat receptor-like kinases (RLK)5. Recently, Kirk et al. developed a tool termed plasmodesmata in silico proteome 1 (PIP1), which made it possible to predict new PD proteins in 22 plant species6. PD varies in permeability and structure during plant development and response to various stresses. Callose (&#946;-1,3-glucan) deposition and hydrolysis at the neck region surrounding the PD is one of the broadly known mechanisms of PD regulation7.
Many pathogenic microbes, including fungi, bacteria, and viruses, can manipulate the PD dilation or structure during their infection2,8,9. Magnaporthe oryzae, the causative agent of rice blast, deploys intracellular invasive hyphae to move from cell to cell through PD8. A bacterial pathogen Pseudomonas syringae pv.&#160;tomato requires an effector protein HopO1-1 for intercellular movement and spread in the host plant through interacting with and destabilizing PDLP7, thus increasing the molecular flux in neighboring cells in Arabidopsis9. However, plant viruses are more versatile in regulating PD during their intercellular transmission, with the viral movement protein (MP) promoting cell-to-cell movement2. Owing to their important function in regulating plant development and growth, as well as their interaction with plant pathogenic microbes, PD has gained increasing attention in recent years. In Arabidopsis thaliana, there are two major types of PD functional proteins, PDLPs (1-8) and PDCBs (1-5), and many of them, e.g., PDLP51,10,11, PDLP112, PDLP613, PDLP714, and PDCB115, were found to play a role in manipulating the PD permeability through regulation of callose deposition. However, some PDLPs were found to have a functional redundancy, e.g., knockout mutants of pdlp1 and pdlp1,2 did not affect the molecular trafficking, although double knockout mutants of pdlp1,3 and pdlp2,3 showed increased plasmodesmal permeability16. Interestingly, downregulation/knockout or over-expression of PDLP5 alone results in an increase or decrease in plasmodesmal permeability, respectively1,17. Recently, Li et al. have found that PDLP5 and PDLP6 function at different cell interfaces13. These results indicate that PDLP5 might have non-redundant functions with other PDLPs.
Due to the critical function of PD in intercellular communication, we developed a protocol for deploying the plant PD proteins PDLP5 and PDCB1 and the viral cell-to-cell movement protein (MP) of the Turnip vein-clearing virus (TVCV) as simple, convenient, and reliable PD markers for cell biology experimentation. For further verification, visualization of PD using aniline blue staining of the sampled tissues proceeded in parallel. The protocols described for PD localization of PDLP5, PDCB1, and TVCV MP can be easily adapted to analyze potential PD localization of any cellular or pathogen-derived proteins in living plants.

Nicotiana benthamiana'da Plasmodesmata'ya Protein Ayıklamasının Konfokal Mikroskopi Analizi

My research is focused on the plant various movement, from cell to cell. And I'm trying to understand the mechanisms of the various plant interactions during the local spread after infection. Recently, we found that plasmodesmata-localized protein 5 can move from cell to cell in nicotiana benthamiana.This result will help us to understand the mechanisms of plasmodesmata functions in the future. Knowing a protein's subcellular localization is quite important for learning its function. This protocol provides good plasmodesmata-localized microbes, PDLP5 and TVCV MP, that can be used during protein localization studies.
