We have developed an automated, high-throughput fingerprinting technique for large genomic DNA fragments suitable for the construction of physical maps of large genomes. In the technique described here, BAC DNA is isolated in a 96-well plate format and simultaneously digested with four 6-bp-recognizing restriction endonucleases that generate 3' recessed ends and one 4-bp-recognizing restriction endonuclease that generates a blunt end. Each of the four recessed 3' ends is labeled with a different fluorescent dye, and restriction fragments are sized on a capillary DNA analyzer. The resulting fingerprints are edited with a fingerprint-editing computer program and contigs are assembled with the FPC computer program. The technique was evaluated by repeated fingerprinting of several BACs included as controls in plates during routine fingerprinting of a BAC library and by reconstruction of contigs of rice BAC clones with known positions on rice chromosome 10.

A fosmid library representing 10-fold coverage of the Histoplasma capsulatum G217B genome was used to construct a restriction-based physical map. The data obtained from three restriction endonuclease fingerprints, generated from each clone using BamHI, HindIII, and PstI endonucleases, were combined and used in FPC for automatic and manual contig assembly builds. Concomitantly, a whole-genome shotgun (WGS) sequencing of paired-end reads from plasmids and fosmids were assembled with PCAP, providing a predicted genome size of up to 43.5 Mbp and 17% repetitive DNA. Fosmid paired-end sequences in the WGS assembly provide anchoring information to the physical map and result in joining of existing physical map contigs into 84 clusters containing 9551 fosmid clones. Here, we detail mapping the Histoplasma capsulatum genome comprehensively in fosmids, resulting in an efficient paradigm for de novo sequencing that uses a map-assisted whole genome shotgun approach.
