The aim of this study was to develop an improved procedure for preparation of chromosome suspensions, and to evaluate the potential of flow cytometry for chromosome sorting in wheat. Suspensions of intact chromosomes were prepared by mechanical homogenization of synchronized root tips after mild fixation with formaldehyde. Histograms of relative fluorescence intensity (flow karyotypes) obtained after the analysis of DAPI-stained chromosomes were characterized and the chromosome content of all peaks on wheat flow karyotype was determined for the first time. Only chromosome 3B could be discriminated on flow karyotypes of wheat lines with standard karyotype. Remaining chromosomes formed three composite peaks and could be sorted only as groups. Chromosome 3B could be sorted at purity >95% as determined by microscopic evaluation of sorted fractions that were labeled using C-PRINS with primers for GAA microsatellites and for Afa repeats, respectively. Chromosome 5BL/7BL could be sorted in two wheat cultivars at similar purity, indicating a potential of various wheat stocks for sorting of other chromosome types. PCR with chromosome-specific primers confirmed the identity of sorted fractions and suitability of flow-sorted chromosomes for physical mapping and for construction of small-insert DNA libraries. Sorted chromosomes were also found suitable for the preparation of high-molecular-weight DNA. On the basis of these results, it seems realistic to propose construction of large-insert chromosome-specific DNA libraries in wheat. The availability of such libraries would greatly simplify the analysis of the complex wheat genome.
