The stability of aging barley calli was investigated with the barley retroelement 1 (BARE-1) retrotransposon specific inter-retrotransposon amplified polymorphism (IRAP) technique. Mature embryos of barley (Hordeum vulgare cv. Zafer-160) were cultured on callus induction MS medium supplemented with 3 mg/L 2,4-D and maintained on the same medium for 60 days. Ten IRAP primers were used in 25 different combinations. The similarity index between 30-day-old and 45-day-old calli was 84%; however, the similarity index between mature embryos and 45-day-old calli was 75%. These culture conditions caused BARE-1 retrotransposon alterations to appear as different band profiles. This is the first report of the use of the IRAP technique in barley in an investigation of callus development.
