Neighbor joining gene tree depicting the relationship of all studied individuals at <i>Xa26</i> locus.

<p>The tree was inferred from 10,000 replicates bootstrap values to represent the evolutionary history of the alleles. The highest bootstrap value of each branch is indicated correspondingly. The scale of branch length is indicated at the bottom. Each allele is indicated with the accession name followed by species name. Phylogenetic analyses were conducted in MEGA4 (Tamura et al. 2007).
