The “mutualism-parasitism continuum” (MPC), a concept introduced by Johnson et al. (1997) to describe the spectrum of plant responses following manipulation of their arbuscular mycorrhizal (AM) status, remains a particularly influential idea at the core of AM research. Two recent articles in Plant and Soil (Johnson and Graham 2012; Smith and Smith 2013) raised some interesting points on the MPC in the arbuscular mycorrhiza (AM). We would like to expand on their points and introduce in this letter the concept of adaptation deficit of constitutively-AM plants that are prevented from becoming mycorrhizal (cAM-NMp). We note that monocultures of constitutively-non-mycorrhizal plants (cNMp) can sometimes extract as much P as constitutively AM plant species (e.g. Veresoglou et al. 2011) and even dominate ecosystems with extreme P limitation (Miller 2005). Moreover, while pathogen susceptibility is higher in cAM-NMp than in constitutively-AM-plants (Veresoglou and Rillig 2012), optimal defense |
