Abstract: The expression pattern and protein structure of maize XYLPs (xylogen-like arabinogalactan proteins) gene family were analyzed by bioinformatics. The distribution of ZmXYLPs on chromosome showed a certain preference. Gene replication events not only played an important role in the expansion and evolution of ZmXYLPs, but also might cause the expansion of gene expression location. According to the structural characteristics,ZmXYLPs could be divided into two categories. Only ZmXYLP10/13/14 contained N-linked glycomodifying sites, and the rest of ZmXYLPs contained O-linked glycomodifying sites. The results showed that the biological function of maize ZmXYLPs might be related to its glycosyl side chain, and its roles were not be limited to the development process of vascular tissue in maize, but also to the process of reproductive development.
