報告內(nèi)容簡介：
All plant cells are surrounded by polysaccharide-based extracellular matrices, called cell walls. These walls underpin cell morphology, thus providing the driving force for plant architecture and protecting plants against their environment. The cell wall polysaccharides are divided into three main classes; pectins, hemicelluloses and cellulose, that together with proteins, ions and sometimes hydrophobic polymers form the cell walls. Nevertheless, the cell wall content and organization can vary substantially across different species, and also across tissues and cell types within a single species. Altering cell wall content and organization may therefore change what a plant looks like and the functional aspects of plant cells. In this talk I will outline efforts done to increase our knowledge of cellulose synthesis, especially how this process may be aided during salt stress exposure. I will also summarize new ways to rapidly identify protein-protein interactions in plant cells to decipher protein complexes involved in cell wall synthesis, sugar sensing and allocation, as well as other processes that drive plant growth.
