Figure 4From: A first survey of the rye (Secale cereale) genome composition through BAC end sequencing of the short arm of chromosome 1RExample of localization of ISBP markers onchromosome arm 1RS. PCR products obtained after amplification with two ISBP primer pairs were visualized on a 2% agarose gel. Templates were DNA of rye (1), wheat (2), wheat-rye 1RS addition (3), flow-sorted chromosome 1R (4), and flow-sorted chromosomes 2R – 7R (5) were used for testing marker specificity. BAC pools of plate SccImp1RShA_0079 (6), SccImp1RShA_0127 (7), SccImp1RSbA_0175 (8), and SccImp1RSbA_0223 served to estimate frequency of ISBP sites on 1RS and as positive control. Both markers were positive in rye, the wheat-rye 1RS addition line and in flow-sorted chromosome 1R and negative in wheat and flow-sorted chromosomes 2R – 7R and thus were considered 1RS specific.
