Figure 1
Chromosomal localization and gene duplication events of OsPTR genes. White ellipses on the chromosomes (vertical bars) indicate the position of centromeres. The scale on the left is in megabases (Mb). Respective chromosome numbers are indicated at the top of each bar. The chromosome order has been arranged to bring duplicated regions in the vicinity. The segmental duplication genes have been connected by straight line. In case of tandemly duplicated genes present in clusters, the genes are marked with rectangles of different colors.
