doi:10.3969/j.issn.1000-7091.2013.01.013

Abstract

Abstract: Localization of 45S RDNA on Elymus canadensis chRomosome was studied by fluoRescence in situ hybRidization( FISH) of chRomosome on Root tip． The Results showed that fouR hybRidization sites weRe detected at the end of shoRt aRm of E． canadensis chRomosome 2 and in secondaRy constRiction( nucleolaR oRganizing Region) on chRomosome 5，which weRe the location of 45S RDNA． And the signal of hybRidization weRe the same intensity．

Key words: E． canadensis, ChRomosome kaRyotyping, FISH, 45S RDNA
