As part of our collaboration in the annotation and analysis of the melon genome (Cucumis melo L.) we have reconstructed the phylome, comprising 22,218 phylogenetic trees. This has enabled mapping of the orthology and paralogy relationships of sequenced plant genomes, and noticing the absence of recent whole-genome duplications in the melon lineage since the ancient eudicot triplication. Also our data suggest that transposon amplification may in part explain the increased size of the melon genome compared with the close relative cucumber. This phylome adds to the phylome of the model plant Arabidopsis thaliana.
The phylome analysis has been published as part of the genome paper (Garcia-Mas et. al. PNAS, in press, PMID:22753475)
