对六种悬浮培养单子叶植物和一种悬浮培养裸子植物的初生细胞壁进行了研究，结果如下：（a）尽管细胞培养物来自不同的组织，但所有六种单子叶植物细胞壁的组成非常相似;（B）悬浮培养的单子叶植物的细胞壁与悬浮培养的双子叶植物和悬浮培养的裸子植物的细胞壁显著不同;（c）阿拉伯木聚糖是主要组分，（d）混合β-1，3; β-1，4-葡聚糖仅在黑麦胚乳细胞的细胞壁制备物中发现，而在其它五种单子叶植物细胞培养物的细胞壁中均未发现，在悬浮培养的道格拉斯冷杉细胞壁中也未发现;（e）所研究的单子叶植物初生细胞壁含有9 - 14%的纤维素、7 - 18%的糖醛酸和7 - 17%的蛋白质;（f）羟脯氨酸占单子叶植物细胞壁的不到0.2%。这些细胞分泌的可溶性胞外多糖的类似数据也包括在内。
The primary cell walls of six suspension-cultured monocots and of a single suspension-cultured gymnosperm have been investigated with the following results: (a) the compositions of all six monocot cell walls are remarkably similar, despite the fact that the cell cultures were derived from diverse tissues; (b) the cell walls of suspension-cultured monocots differ substantially from those of suspension-cultured dicots and from the suspension-cultured gymnosperm; (c) an arabinoxylan is a major component (40% or more by weight) of monocot primary cell walls; (d) mixed β-1,3; β-1,4-glucans were found only in the cell wall preparations of rye grass endosperm cells, andnotin the cell walls of any of the other five monocot cell cultures nor in the walls of suspension-cultured Douglas fir cells; (e) the monocot primary cell walls studied contain from 9 to 14% cellulose, 7 to 18% uronic acids, and 7 to 17% protein; (f) hydroxyproline accounts for less than 0.2% of the cell walls of monocots. Similar data on the soluble extracellular polysaccharides secreted by these cells are included.
