Abstract
A bovine artificial chromosome (BAC) library of 105 984 clones has
been constructed in the vector pBeloBAC11 and organized in 3-dimension
pools and high density membranes for screening by PCR and
hybridization. The average insert size, determined after analysis of
388 clones, was estimated at 120 kb corresponding to a four genome
coverage. Given the fact that a male was used to construct the
library, the probability of finding any given autosomal and X or Y
locus is respectively 0.98 and 0.86. The library was screened for 164
microsatellite markers and an average of 3.9 superpools was positive
for each PCR system. None of the 50 or so BAC clones analysed by FISH
was chimeric. This BAC library increases the international genome
coverage for cattle to around 28 genome equivalents and extends the
coverage of the ruminant genomes available at the Inra resource center
to 15 genome equivalents.
