Abstract
Tripsacum dactyloides (2n = 2x = 36) is an ancient tetraploid species. Here we report that T. dactyloides chromosomes contain an extraordinary tertiary constriction, which causes a radical and distant separation of a terminal segment from the chromosome. The relationships between extraordinary tertiary constriction and segmental chromosome loss as well as karyotype evolution of polyploid species are discussed.
摘要
摩擦禾（2n = 2x = 36）是一种古老的四倍体物种。在此我们报告，摩擦禾染色体包含一个异常的三级缢痕，该缢痕导致染色体末端片段发生剧烈且远距离的分离。文中讨论了异常三级缢痕与染色体片段丢失以及多倍体物种核型进化之间的关系。
