Distance tree of I2 homologues from different genotypes of tomato. The 76 I2 homologues from tomato form five clades, supported by high bootstrap numbers. Members in clades I, III and V are evenly related homologues, and are extensive chimeras. Members within clades II and IV are highly conserved homologues from different genotypes. The first part of the gene name represents accession/cultivar name, and the numbers in bracket (if any) show gene’s position (sub-locus). Genes from the same genotype spread in the tree. Numbers on nodes are bootstrap values, and values <65 are not shown.
