Amborella Genome Organization
The Amborella genome shows microsynteny with other plant genomes.
Illustrated here is a physical map of a 0.65 Mb region of the Amborella nuclear
genome (highlighted in yellow) showing synteny with segments in each of the
Arabidopsis, poplar, grape, and rice genomes. Two homologous segments are
shown in each case: one above and one below the Amborella map. The physical
map is based on high information content fingerprinting of an Amborella BAC
library. Synteny was inferred over 5 Mb tracts of sequenced genomes on the
basis of BAC-end sequences matching the reference genomes with TBLASTX bit
scores of greater than 80. Red and green ovals depict BAC-end Amborella
sequences with significant hits to known transposable elements and
protein-coding genes, respectively. From Soltis et al. (2008)
