Abstract
We have investigated the use of AFLP® technology as a tool for the high throughput enrichment of Radiation Hybrid (RH) maps. The 3000 rad TM112 bovine RH panel was assayed with 37 EcoRI/TaqI AFLP primer combinations. The number of selective nucleotides used during PCR was increased to seven, to reduce the complexity of the AFLP profile and minimise the overlap between hamster and bovine bands co-amplified from hybrid cell clones. Seven-hundred-forty-seven bovine AFLP bands were amplified that could be distinguished following electrophoresis. Repeatability was tested within and between laboratories on independent template preparations and an error rate of 1.3% found. Two-point linkage analysis clustered 428 AFLP fragments in 39 linkage groups of at least 4 markers. Multi-point maps were constructed for 5 sample linkage groups. The study demonstrated that the AFLP approach could be used to rapidly screen for the most informative clones during panel construction and to increase the number of markers on RH maps, which could be useful for joining linkage groups formed by other markers. The use of AFLP markers as anchor points between existing RH maps and other physical maps, such as BAC contigs, is also discussed.
