果胶是存在于所有植物初生细胞壁中的复杂多糖家族。果胶多糖的复杂结构，以及植物保留了合成果胶所需的大量基因。表明果胶在植物生长发育中具有多种功能。在这篇综述中，我们总结了目前水平的理解果胶的一级和三级结构，并描述了新的方法，可能是有用的研究本地化的果胶结构在植物细胞壁。我们还讨论了进展，我们的理解如何果胶是生物合成和审查的生物活性和可能的模式的果胶低聚糖被称为寡聚半乳糖醛酸。我们提出了我们的观点的关键问题，果胶结构。生物合成以及未来十年需要解决的问题。随着植物界努力了解植物表达的数千个tms的功能，大量这些基因可能参与果胶的合成，周转，生物活性和重组。基因的结合。要充分了解果胶的功能和生物合成，必须采用分子、生物化学和化学方法。(C)2001爱思唯尔科技有限公司版权所有。
Pectin is a family of complex polysaccharides present in all plant primary cell walls. The complicated structure of the pectic polysaccharides, and the retention by plants of the large number of genes required to synthesize pectin. suggests that pectins have multiple functions in plant growth and development. In this review we summarize the current level of understanding of pectin primary and tertiary structure, and describe new methods that may be useful to study localized pectin structure in the plant cell wall. We also discuss progress in our understanding of how pectin is biosynthesized and review the biological activities and possible modes of action of pectic oligosaccharides referred to as oligogalacturonides. We present our view of critical questions regarding pectin structure. biosynthesis. and function that nod to be addressed in the coming decade. As the plant community works towards understanding the Functions of the tms of thousands of gents expressed by plants, a large number of those genes are likely to be involved in the synthesis, turnover, biological activity, and restructuring of pectin. A combination of genetic. molecular, biochemical and chemical approaches will be necessary to fully understand the Function and biosynthesis of pectin. (C) 2001 Elsevier Science Ltd.
