Phylogenetic tree showing the relationships among 250 RGADEs predicted within the COMPGG transcripts dataset. Cladogram was obtained with FastTree software and the Le-Gascuel model of amino acid evolution. a Full cladogram, with subclades collapsed. b, c and d Expanded RGA subclades. Expression profiles from sugarcane genotypes of IAC66–6 and SP80–3280 are represented as Log2 Fold Change values (inoculated/control) in the heatmap, if significant at P < 0.05 in at least one sugarcane genotype. In the heatmap, blue squares represent down-regulation, whereas red squares represent up-regulation; grey squares represent no transcript expression. The statistical significance of expression is fully presented in Additional file 2. Predicted protein domains are depicted with colors together with geometric forms accordingly to legend. RGAs not having depicted domains were predicted only based on orthology during BLASTp searches. Branches colors indicate RGA classes according to legend. Dashed grey lines indicate the amino acid sequence length. Green stars highlight clades where sugarcane genotypes shared related expression profiles. Yellow stars highlight clades where sugarcane genotypes had distinct expression profiles of RGADE
