Phylogenetic analysis of the reannotated Heinz 1706 NB-LRR genes. Full NB-ARC domains of 240 reannotated NB-LRR genes were used together with 30 functionally characterized plant R genes (green font) to do a maximum likelihood analysis based on the Whelan and Goldman model. Clades are collapsed based on a bootstrap value over 79 and numerated. The TNL clade is drawn with a yellow background. Expressed genes, as identified by the cDNA RenSeq analysis, are in red font. Evolutionary analyses were conducted in MEGA5. Labels show the gene IDs (red for expressed NB-LRR genes; black for not-expressed genes). Bootstrap values higher than 79 (out of 100), are indicated above the branches. The tree is drawn to scale, with branch lengths proportional to the number of substitutions per site.
