The phylogenic trees of Avr -genes. In this Figure, each tree represents the phylogenetic relationship of one AVR gene. The colored shape indicates the origin of the strain, and the number of strains is labeled behind the shape if there are more than one member at the the same position. In the tree of PWL2, there are only two kinds of alleles. One of them is the wild type, which is intoxical, while the other is inefficient and toxical.
