A population of Arabidopsis thaliana recombinant inbred lines was constructed and used to develop a high-density genetic linkage map containing 252 random amplified polymorphic DNA markers and 60 previously mapped restriction fragment length polymorphisms. Linkage groups were correlated to the classical genetic map by inclusion of nine phenotypic markers in the mapping cross. We also applied a technique for local mapping that allows targeting of markers to a selected genome region by pooling DNA from recombinant inbred lines based on their genotype. We conclude that random amplified polymorphic DNAs, used in conjunction with a recombinant inbred population, can facilitate the genetic and physical characterization of the Arabidopsis genome and that this method is generally applicable to other organisms for which appropriate populations either are available or can be developed.
