This paper is a comment to a paper published in this issue [See New Phytologist (2010) 186, 514-525] which indirectly demonstrated the antiquity of the plant-arbuscular mycorrhizas (AM) fungal association. They elegantly used molecular tools, in an evo-devo manner, to show that this widespread association is probably homologous in all lineages of land plants (Embryophyta). Ironically, the mycorrhizal association is more ancient than the roots defining it (-rhiza), which arose within vascular plants only. Arbuscular mycorrhizas and other symbiosis in land colonization are discussed. The sym genes are investigated, which have been instrumental in the identifying the first steps of symbiosis establishment. This paper also cited examples to prove that the presence of the sym genes in non-AM plants opens the possibility of a repeated recruitment of the same transduction machinery during independent emergence of the AM symbiosis. |
