title: Fractionation of synteny in a genomic region containing tandemly duplicated genes across glycine max, Medicago truncatula, and Arabidopsis thaliana.
abstract: Extended comparison of gene sequences found on homeologous soybean Bacterial Artificial Chromosomes to Medicago truncatula and Arabidopsis thaliana genomic sequences demonstrated a network of synteny within conserved regions interrupted by gene addition and/or deletions. Consolidation of gene order among all 3 species provides a picture of ancestral gene order. The observation supports a genome history of fractionation resulting from gene loss/addition and rearrangement. In all 3 species, clusters of N-hydroxycinnamoyl/benzoyltransferase genes were identified in tandemly duplicated clusters. Parsimony-based gene trees suggest that the genes within the arrays have independently undergone tandem duplication in each species.
