Abstract: Xylan is a major component of hemicellulose that widely present in the cell walls of various types of plants and is essential for the growth and development of plants. Many studies have shown that the content and structure of xylan in the cell wall have a significant impact on the processing characteristics of biomass. Hence, understanding the mechanism of xylan biosynthesis will enable us to modify the cell wall through genetic engineering. During last decade, many genes involved in xylan biosynthesis have been characterized in the model plant Arabidopsis and some important grain and cash crops. This article reviews these recent findings and discusses the potential applications of xylan biosynthesis genes in biomass energy and related fields.
