Supplementary Figure 6. Maximum likelihood phylogram comparing NBS domains of the TIR resistance gene homologs from chickpea (Ca) with Medicago truncatula (Mt).

Monophyletic clades are collapsed into filled triangles, with numbers at the base of the triangle indicating the number of genes in the given clade. Green, Medicago truncatula; orange, clades with chickpea sequences for the assembled genome only; black, clades containing both sequences from the chickpea genome and NBS domains obtained by PCR. Dual numbers at the base of black clades indicate number of PCR/genome sequences, respectively.
