摘要/Abstract

摘要： 通过生物信息学的方法对玉米木质形成素类阿拉伯半乳糖蛋白(xylogen-like arabinogalactan proteins,XYLPs)基因家族的表达模式和蛋白结构进行了分析。ZmXYLPs基因家族成员在染色体上的分布具有一定的偏好性。基因复制事件不仅在基因家族成员数量的扩张和进化中发挥重要作用,同时还可能引起基因表达部位的扩张。根据ZmXYLPs蛋白结构特点,可将其分为两大类。其中仅ZmXYLP10/13/14蛋白存在N连接的糖修饰位点,其余ZmXYLPs蛋白均为O连接糖修饰位点。结果显示,玉米ZmXYLPs的生物学功能可能与其糖基侧链有关,并且其作用并不局限于维管组织发生过程,可能也参与生殖发育过程。

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.
