Phylogenetic position of the species investigated here in a broader context1. Lineages not
including one of the species discussed in our study are indicated by dotted lines. Prosopis
juliflora and Piptadenia flava were not included in the original study, their phylogenetic
position was estimated based on the high similarity of the sequences shared with included
representatives of the respective genus. The relationships within Acacia subg. Acacia are
according the analysis displayed in Supplementary Figure 1. Constitutive EFN secretion (red)
has been observed only in the myrmecophytic Acacia species, while inducible EFN flow
(green) is found in different phylogenetic lineages including Phaseolus lunatus2, which is
member of the subfamily Faboideae.
