Investigation of cell wall proteins of C. sinensis leaves by combining cell wall proteomics and N-glycoproteomics

Cell wall proteomics of crops

Cell wall proteins play key roles in cell structure and metabolism, cell enlargement, signal transduction, responses to environmental stress, and many other physiological events. Agricultural crops are often used for investigating stress tolerance because cultivars with differing degrees of tolerance are available. Abiotic and biotic stress factors markedly influence the geographical distributi...

Cell wall proteins: a new insight through proteomics.

Cell wall proteins are essential constituents of plant cell walls; they are involved in modifications of cell wall components, wall structure, signaling and interactions with plasma membrane proteins at the cell surface. The application of proteomic approaches to the cell wall compartment raises important questions: are there technical problems specific to cell wall proteomics? What kinds of pr...

Arabidopsis Regenerating Protoplast: A Powerful Model System for Combining the Proteomics of Cell Wall Proteins and the Visualization of Cell Wall Dynamics

The development of a range of sub-proteomic approaches to the plant cell wall has identified many of the cell wall proteins. However, it remains difficult to elucidate the precise biological role of each protein and the cell wall dynamics driven by their actions. The plant protoplast provides an excellent means not only for characterizing cell wall proteins, but also for visualizing the dynamic...

Cell wall cementing materials of grass leaves.

Treatment of grass leaves with either a purified pectin lyase of Aspergillus japonicus or a purified xylanase of Trichoderma viride could lead to the isolation of some single leaf cells. However, a mixture of pectin lyase and xylanase brought about more rapid isolation of single cells than did either of the two enzymes alone, indicating a synergistic effect. Analysis of the components released ...
