dc.description.abstract | Background: Although melon (Cucumis melo L.) is an economically important fruit crop, no genome-wide
sequence information is openly available at the current time. We therefore sequenced BAC-ends representing a
total of 33,024 clones, half of them from a previously described melon BAC library generated with restriction
endonucleases and the remainder from a new random-shear BAC library.
Results: We generated a total of 47,140 high-quality BAC-end sequences (BES), 91.7% of which were paired-BES.
Both libraries were assembled independently and then cross-assembled to obtain a final set of 33,372 nonredundant, high-quality sequences. These were grouped into 6,411 contigs (4.5 Mb) and 26,961 non-assembled BES
(14.4 Mb), representing ~4.2% of the melon genome. The sequences were used to screen genomic databases,
identifying 7,198 simple sequence repeats (corresponding to one microsatellite every 2.6 kb) and 2,484 additional
repeats of which 95.9% represented transposable elements. The sequences were also used to screen expressed
sequence tag (EST) databases, revealing 11,372 BES that were homologous to ESTs. This suggests that ~30% of the
melon genome consists of coding DNA. We observed regions of microsynteny between melon paired-BES and six
other dicotyledonous plant genomes.
Conclusion: The analysis of nearly 50,000 BES from two complementary genomic libraries covered ~4.2% of the
melon genome, providing insight into properties such as microsatellite and transposable element distribution, and
the percentage of coding DNA. The observed synteny between melon paired-BES and six other plant genomes
showed that useful comparative genomic data can be derived through large scale BAC-end sequencing by
anchoring a small proportion of the melon genome to other sequenced genomes. | ca |
