Development of microsatellite markers specific for the short arm of rye (Secale cereale L.) chromosome 1

Popis výsledku v původním jazyce

We developed 74 microsatellite marker primer pairs yielding 76 polymorphic loci, specific for the short arm of rye chromosome 1R (1RS) in wheat background. Four libraries enriched for microsatellite motifs AG, AAG, AC and AAC were constructed from DNA offlow-sorted 1RS chromosomes and 1,290 clones were sequenced. Additionally, 2,778 BAC-end-sequences from a 1RS specific BAC library were used for microsatellite screening and marker development. From 724 designed primer pairs, 119 produced 1RS specific bands and 74 of them showed polymorphism in a set of ten rye genotypes. We show that this high attrition rate was due to the highly repetitive nature of the rye geonome consisting of a large number of transposable elements. We mapped the 76 polymorphic loci physically into three regions (bins) on 1RS; 29, 30 and 17 loci were assigned to the distal, intercalary and proximal regions of the 1RS arm, respectively. The average polymorphism information content increases with distance from the c
