The purpose of this study is to develop the EEG (Euchromatin Enriched Genomic) DNA library of wheat, barley, rye and oat. Mcr A and Mcr BC system in DH5 alpha bacteria cell line and Kuemkangmil, Olbori, Olhomil and Olgwiri were used for materials in our experiments. EEG colonies have been constructed by using junk DNA exclusion. We analyzed the genetic information of the colonies using blast searches of NCBI and GRAMENE web sites. One hundred eighty-four, 65, 79 and 119 STS primer pairs were developed using sequencing data of selected colonies in Kuemkangmil, Olbori, Olhomil and Olgwiri respectively. Twenty-eight and forty-two percent of designed primer pair showed polymorphism using six endoucleases in Kuemkangmil, Olbori, Olhomil and Olgwiri germplasm respectively. These primers could be useful for specific allele tagging in mapping populations and germplasm and for the study of functional genomics of wheat, barley, rye and oat.
