Plant cell walls are primarily composed of the cellulose and hemicellulose, embedded in a polysaccharide gel called pectin. These cell wall components interact with one another to create an environmental barrier that meets the needs of the cell during growth and differentiation. In addition the wall provides an extracellular medium through which adjacent cells are connected to each other. Consequently, information concerning plant cell wall structure and how it can be modified as cells develop and adapt to a changing environment is valuable and has many applications in agriculture and forestry. We study a specialized cell type of the Arabidopsis thaliana seed coat that makes large quantities of cell wall polysaccharides.

植物细胞壁主要由纤维素和半纤维素组成，它们被包裹在一种叫做果胶的多糖凝胶中。这些细胞壁成分相互作用，形成一个环境屏障，满足细胞生长和分化的需要。此外，细胞壁提供细胞外介质，相邻细胞通过细胞壁相互连接。因此，有关植物细胞壁结构的信息以及细胞如何随着细胞的发育和适应不断变化的环境而改变细胞壁结构的信息是有价值的，并且在农业和林业中有许多应用。我们研究了一种特殊的细胞类型的拟南芥种皮，使大量的细胞壁多糖。
