TI  - Chromosome-level homeology in paleopolyploid soybean (Glycine max) revealed 
      through integration of genetic and chromosome maps.
PG  - 1893-900
AB  - Soybean has 20 chromosome pairs that are derived from at least two rounds of 
      genomewide duplication or polyploidy events although, cytogenetically, soybean 
      behaves like a diploid and has disomic inheritance for most loci. Genetically 
      anchored genomic clones were used as probes for fluorescence in situ 
      hybridization (FISH) to determine the level of postpolyploid chromosomal 
      rearrangements and to integrate the genetic and physical maps to (1) assign 
      linkage groups to specific chromosomes, (2) assess chromosomal structure, and (3) 
      determine the distribution of recombination along the length of a chromosome. 
      FISH mapping of seven putatively gene-rich BACs from linkage group L (chromosome 
      19) revealed that most of the genetic map correlates to the highly euchromatic 
      long arm and that there is extensive homeology with another chromosome pair, 
      although colinearity of some loci does appear to be disrupted. Moreover, mapping 
      of BACs containing high-copy sequences revealed sequestration of high-copy 
      repeats to the pericentromeric regions of this chromosome. Taken together, these 
      data present a model of chromosome structure in a highly duplicated but 
      diploidized eukaryote, soybean.
