Abstract
Primary cell walls of Zea mays prepared in a glycerol medium are capable of autolysis in vitro. Autolysis results in solubilization of about 10% of the wall substance during an 8 hour incubation period. Approximately 10% of the solubilized material is glucose and the remainder consists of an unidentified polymer which yields only glucose upon hydrolysis. Cell wall autolysis is a linear function of time of incubation and of wall concentration. The autolytic process occurs optimally over the pH range of 5.5 to 6.5. The possible relationship between autolytic capacity and capacity for elongation is discussed.
摘要
在甘油介质中制备的玉米原生细胞壁能够在体外进行自溶。自溶导致在 8 小时孵育期间约 10%的壁物质溶解。大约 10%的溶解物质是葡萄糖，其余部分是一种未鉴定的聚合物，水解后仅产生葡萄糖。细胞壁自溶是孵育时间和细胞壁浓度的线性函数。自溶过程在 pH 值为 5.5 到 6.5 的最佳范围内发生。自溶能力和伸长能力之间的可能关系进行了讨论。
