Distribution of annexin genes in duplicated genomic regions in various plant species.

The segmental duplicated annexin genes for Arabidopsis and rice were obtained from (http://wolfe.gen.tcd.ie/athal/dup) and (http://rice.plantbiology.msu.edu/segmental_dup/500kb/segdup_500kb.shtml), respectively. For poplar and soybean, the segmental duplications were identified based on the chromosome mapping in collinear regions in Plaza database (http://bioinformatics.psb.ugent.be/plaza_v1/dotplot/). The annexin genes separated by two to five genes were identified as tandemly duplicated genes.
