Abstract:
Arbuscular mycorrhizal (AM) fungi inhabit the root cortical cells of most plants and obtain photosynthates from the host plants while they transfer mineral nutrients from the soil to the hosts. In this review, we first summarize recent progress regarding signal molecules involved in the recognition of each symbiont, the signaling pathways in the host plants, and the characteristics of AM-inducible nutrient transporters, which were elucidated mainly using model legumes. Then, we summarize studies on the colonization by AM fungi of lower plants and of the roots of major crops. There are not only "AM-responsive" crops like maize, sorghum, and soybean but also "AM-nonresponsive" ones like wheat, barley, and rice. Finally, we mention the worldwide problems of limited and biased agricultural resources and discuss future directions as to how we can make use of AM symbiosis for improving crop production and establishing sustainable agriculture.
