摘要: pAeca212 is 204 bp in length, and the G + C content is 51%. It disperses on all seven chromosome pairs of Aegilops caudata except centromeres and secondary constrictions. Compared with the 316893 DNA sequences registered in Genbank/EMBL/DDJB/PDB, pAeca212 is a new C-genome specific repetitive sequence. The results of genomic specificity analysis of pAeca212 show that there are no hybridization signals detected in all donor Poaceae plants except in rye. pAeca212 is a very useful molecular marker in the study of the origin of Triticeace and the detection of C chromatin in wheat background.
