Relationship of TAL effector genes in Xoo strains PXO99A and MAFF. The individual genes, distributed among nine loci in PXO99A and eight in MAFF, are represented by open arrows and labeled as described in the text. Pseudogenes (truncated genes or genes with early stop codons) are indicated by an apostrophe. Genes that have identical repeat regions based on number of repeats and identity at the twelfth and thirteenth codons are connected with a black dashed line. Blue dashed lines connect genes with nearly identical repeat regions (see text). Names of previously characterized genes are centered above or below the corresponding open arrow. Colored boxes indicate TAL gene clusters (not to scale), with the same color representing loci at the same relative positions in the two genomes. Locus 4 in PXO99A and locus 3 in MAFF are uniquely positioned in their respective genomes. The solid black rectangle and arrows beneath it represent the 212 kb direct repeat in the PXO99A genome.
