摘　　要：The plant cell wall is the first physical and defensive barrier against pathogens.The plant cell wall usually undergoes dynamic remodeling as an immune response to prevent infection by pathogens.In this review,we summarize advances on relationship between cell wall and immunity in plants.In particular,we outline current progresses regarding the regulation of the cell wall components,including cellulose,hemicellulose,pectin and lignin,on plant disease resistance.We also discuss the impacts of cell wall-derived cellodextrin,oligogalacturonic acid and xyloglucan/xylan oligosaccharides as potent elicitors or signal molecules to trigger plant immune response.We further propose future studies on dissecting the molecular regulation of cell wall on plant immunity,which have potentials in practical application of crop breeding aiming at improvement of plant disease resistance.
