中文摘要：

苯并恶唑嗪酮（benzoxazinoids,BXs）是植物体内一种重要的次生代谢物,因其具有防御作用和化感作用得到了广泛的关注和研究。随着基因组学及分子生物学的发展,苯并恶唑嗪酮的生物合成在分子领域的研究取得了很大的进展。介绍了苯并恶唑嗪酮概况、苯并恶唑嗪酮的功能以及苯并恶唑嗪酮生物合成参与基因及表达调控。

英文摘要：

Benzoxazinoids（ BXs） are important secondary metabolites in plants. There has been a wide range of attention and research of them because of their role in defensive and allelopathy. With the development of genomics and molecular biology,the BXs biosynthesis and other molecular areas research has made great progress. The BXs profile,the function of BXs,the genetic basis of BXs biosynthesis and expression regulation were briefly introduced.
