Plant cell wall in symbiotic interactions. Pectins

Since plant cells, unlike animals, are immobile and limited by rigid cell walls, often the properties of the plant extracellular matrix play a crucial role in the plant development. The extracellular matrix, in particular the cell walls, are involved in the molecular dialogue between partners during the interaction of plants and microorganisms during the formation of legume-rhizobial symbiosis (N.J. Brewin, 2004; M.K. Rich et al., 2014). Legume-rhizobial symbiosis is a convenient model for studying changes in the composition of the plant cell wall caused by interactions with bacteria. Colonization of host cells with nodule bacteria, rhizobia, involves the sequential reorganization of the plant-microbial interface. The bacterial components of the symbiotic interface include various surface polysaccharides (A.V. Tsyganova et al., 2012). Plant components include the cell wall, the extracellular matrix and the plasma membrane. In this review, we have summarized the data demonstrating the involvement of pectins, the polysaccharides of the cell wall matrix, in the legume-rhizobial symbiosis (K...
