Abstract
The vast majority of land plants transfer part of the organic carbon
they produce by photosynthesis to arbuscular mycorrhizal (AM)
fungi inside their root cells; the fungi in turn help plants to take up
nutrients and water from the soil. This carbon can subsequently be
acquired from mycorrhizal fungi by rare nonphotosynthetic
‘mycoheterotrophic’ plants that tap into the same fungal network.
However, recent findings suggest that carbon uptake from AM
fungi may exist among some green plants too. If so, this would
qualify them as partial mycoheterotrophs (mixotrophs) rather than
as pure autotrophs. Here, we discuss the evolutionary, ecophysiological,
morphological, genetic, and environmental evidence for the
existence and prevalence of this trait. We conclude that there is
strong, albeit indirect, evidence for its existence, although its
taxonomic distribution remains to be determined. This knowledge
gap currently prevents us from inferring the magnitude of AM
partial mycoheterotrophy in terrestrial ecosystems, which in turn
severely limits our understanding of its role in plant establishment
and survival and in ecosystem structure and function.
