Illegitimate recombination (IR) signatures flanking different regions of the 20 Rdr1 -TNL homologs. a) IR-flanking TIR domain. b) IR-flanking NBS domain. c) IR-flanking LRR domain. Two to five base IR signatures are framed. The sequence region with random duplication is underlined. Certain sequence parts of the IR signatures are imperfect with few mismatches. In each case, duplication of at least one sequence is visible following the IR signature.
