Ancestral state reconstruction of trophic mode and symbiotic association using bayestraits ‘MultiState’ analysis. (a) The posterior probability of trophic modes of the common ancestor of orchids under a relaxed definition of partial mycoheterotrophy (Supporting Information Notes S1). AU, autotrophy; PMH, partial mycoheterotrophy; MH, full mycoheterotrophy. (b) The posterior probability of trophic modes of the common ancestor of orchids under a strict definition of PMH (Notes S1). (c) The posterior probability of symbiotic associations of the common ancestor of orchids. Symbiotic associations are represented by the lifestyles of fungal families that one orchid associates with. R, ‘rhizoctonias’; E, ectomycorrhizal fungi; S, saprotrophic fungi.
