摘要: Pectic polysaccharides are major components of extendable primary cell walls and amongst the most complex macromolecules in nature. The three pectic polymers homogalacturonan, rhamnogalacturonan I II. Here we review current understanding how these structurally distinct integrated into wall networks they function matrices. We also structure properties can be modified muro contribute to environments for controlled slippage cellulose cross-linking glycan network during expansion processes.
