TL;DR: An analysis of the current state of knowledge of symbiotic fungal associations in 'lower' plants is provided and it is shown, probably for the first time, that glomalean fungi forming typical VA mycorrhiza with a higher plant can colonize a thalloid liverwort, producing arbuscules and vesicles in the hepatic.

TL;DR: A spectrum of fungal impacts is revealed in which some species respond mutualistically, while others, putative hosts or nonhosts, are antagonised, showing reduction of yield and survivorship and, hence, a loss of fitness relative to plants grown without VA fungi.

TL;DR: Examination of seminal papers written by plant community ecologists is examined and some of ‘the most striking mysteries’ which they reveal are highlighted and it is recommended that scientists involved in research on mycorrhiza extend their vision beyond the limited horizons which are currently so often defined by considerations of the phosphorus nutrition of individual host plants.

TL;DR: It is shown using autoradiography that transfer of carbon between plants connected by VA mycorrhizal mycelium occurs primarily by the direct hyphal pathway and the magnitude of the transfer is strongly influenced by shading of ‘receiver’ plants indicating that movement is governed by source–sink relationships.
