The plant cell wall, which is composed of cellulose, hemicellulose, pectin and lignin, is a dynamically changing network structure, that not only plays the role of a key line of defense in the process of plant resistance to external pressure and adaptation to environmental changes, but also plays the role of an information hub in the process of signal transmission. When the cell wall is damaged, cells sense cell wall changes and initiate early immune responses, such as hormonal changes, alterations in wall composition and modifications, and the production of disease-resistant secondary metabolites. Although the importance of the cell wall in plant immunity is widely recognized, the specific molecular mechanisms by which cell wall damage triggers immune responses remain poorly understood. The application of in situ unlabeled imaging techniques in plant cells is gradually increasing and has become an important tool for studying cell wall structure and function. This paper describes the interaction mechanism between the plant cell wall and the immune response to provide a scientific basis for a deeper understanding of plant life activities and improve crop disease resistance, and describes in situ non-labeled imaging of the cell wall to provide more technological options for advancing the study of the cell wall in the immune response.
