Abstract
The detailed arrangement of 563 YAC clones comprising four contigs covering ∼17 Mbp of chromosome 4 is presented. YAC clones were positioned relative to each other and to markers by taking into account marker and end fragment hybridization data and the sizes of all YAC clones. This analysis made it possible to estimate physical distances between the majority of chromosome 4 markers. It also identified a relatively large number of YAC clones containing chimaeric inserts. The YAC contig map of the Columbia ecotype presents an important resource for map‐based cloning experiments, rapid mapping of DNA sequences and large‐scale genomic sequencing programs.
