| Abstract: | Background Well preserved genomic colinearity among agronomically important grass species such as rice, maize, Sorghum, wheat and barley
provides access to whole-genome structure information even in species lacking a reference genome sequence. We investigated
footprints of whole-genome duplication (WGD) in barley that shaped the cereal ancestor genome by analyzing shared synteny
with rice using a ~2000 gene-based barley genetic map and the rice genome reference sequence. |
