Genetic and contig map of a 2200-kb region encompassing 5.5 cM on chromosome 1 of Arabidopsis thaliana.
In the course of the isolation of the MONOPTEROS ( MP) gene, required for primary root formation in Arabidopsis thaliana, a yeast artificial chromosome (YAC) contig encompassing approximately 2200 kilobases corresponding to 5.5 cM on the top arm of chromosome 1 was established. Forty-six YAC clones were characterized and 12 new restriction fragment length polymorphism (RFLP) markers are presented. Three new codominant amplified polymorphic sequence (CAPS) markers were generated that enabled high resolution genetic mapping and correlation of physical and genetic distances along the contig. The map contributes to the completion of a physical map of the Arabidopsis genome and should facilitate positional cloning of other genes in the region as well as studies on genome organization. We also present another set of 11 physically linked probes, as well as mapping data for additional RFLP markers within a broader interval of 10.4 cM.[1]References
