Inferring barley genome duplications using the synteny to rice. At least seven barley genome duplications could be inferred by analyzing the location of mapped ESTs among the seven barley chromosomes (Hv1H – Hv7H) and their best rice homologs (putative orthologs) among the 12 rice chromosomes (Os01 – Os12) with respect to rice segmental genome duplications (indicated by connecting lines of the same color). Relationships between second-best rice homologs (putative paralogs) of the same markers to the corresponding paralogous region in rice are shown in grey. Two hypothetical additional AD's involving Hv5H – Os03/Hv2H – Os07 and Hv4H – Os11/Hv5H – Os12 confirmed by less than 8 orthologous gene pairs to one of the duplicated rice regions are not shown.
