细胞壁对于植物生长发育及抗胁迫均具有基础性作用。乙酰化作为细胞壁多聚物的主要修饰形式,其修饰水平和位置对细胞壁理化性质和结构具有重要影响。研究表明,模式植物拟南芥有三类蛋白参与细胞壁多糖的乙酰化修饰,其中TBL(Trichome Birefringence-Like)属多蛋白成员家族。木聚糖是水稻中最主要的半纤维素,且主链和侧链均存在高度的乙酰化修饰,但目前对水稻细胞壁多糖乙酰化修饰的分
Cell wall for plant growth and resistance to stress have a fundamental role. Acetylation as a major modification of cell wall polymers, the level of its modification and location of the physical and chemical properties of cell walls and structure have a significant impact. Studies have shown that three types of Arabidopsis thaliana proteins involved in cell wall polysaccharide acetylation, including TBL (Trichome Birefringence-Like) is a member of the multi-protein family. Xylan is the most important hemicellulose in rice with high degree of acetylation in the main chain and side chain. However,
