近些年来从小麦族植物中分离到了许多 DNA重复序列 ,并对其组织结构特点、物种分布特异性和在染色体上的分布特征做了广泛的研究。其中一些重复序列已被成功地用于检测导入小麦的外源染色质和小麦族有关种属的进化研究。本文就以上诸方面进行了简要介绍。
In recent years, many DNA repetitive sequences have been isolated from plants of the genus Triticeae, and extensive studies have been carried out on their characteristics of tissue structure, species distribution and distribution on chromosomes. Some of these repeats have been successfully used in evolutionary studies to detect exogenous chromatin and wheat-related species introduced into wheat. This article on the above aspects were briefly introduced.
