Statistically significant recombination tracks and breakpoints detected in NLRs and DEFLs. a Proportion of recombination tracks per species as percentage of the total number of recombination events detected with Geneconv. Numbers besides each bar indicate the actual number of recombination tracks identified in each species and their average length in each subfamily of NLRs. b Proportion of recombination tracks per species as percentage of the total number of recombination events detected with Geneconv in the DEFL family. Numbers besides each bar indicate the actual number of recombination tracks identified in each species in all DEFL genes analyzed. c Number of recombination tracks identified with Geneconv along the residues encoding three major NLR protein domains. Tracks designed as “out of domain” were identified between the boundaries of CC/TIR and NB-ARC or between NB-ARC and the LRR domain. “After LRR” indicates the amino acid residues after the last identified LRR repeat. d Number of breakpoints identified with GARD in the regions coding major NLR protein domains. A breakpoint indicates the beginning of a region in the multiple sequence alignment that yields a phylogeny significantly different from those based on other nucleotide positions. This phylogenetic incongruence might be due to recombination events or to significant differences in the rates of nucleotide substitution across coding sequences. e Number of recombination tracks identified with Geneconv along the residues encoding the signal peptide, the mature peptide or both regions encoding DEFLs. f Number of breakpoints identified with GARD in the regions encoding the signal or the mature peptides of DEFLs
