The effect of drought stress and mycorrhizal symbiosis on the colonization, root and leaf phosphorous content, root and leaf phosphatase activity, root volume and area as well as shoot dry weight of a variety of hulless barley were evaluated using a completely randomized experimental design (CRD) with 3 replications. Treatments were three levels of drought stress of 30, 60 and 90% field capacit...

The conquest of the land by plants, c. 470 million years ago, was made possible by the arbuscular mycorrhizal symbiosis (Selosse et al., 2015). In fact, the evolution of that symbiosis was so successful that plant roots have to fit into an arbuscularmycorrhizal world. But that conclusion at the same time hides a paradox. If the arbuscular mycorrhizal symbiosis was so successful, which empty nic...

Several studies, performed mainly in pots, have shown that arbuscular mycorrhizal symbiosis can mitigate the negative effects of water stress on plant growth. No information is available about the effects of arbuscular mycorrhizal symbiosis on berseem clover growth and nitrogen (N) fixation under conditions of water shortage. A field experiment was conducted in a hilly area of inner Sicily, Ita...

The mutualistic symbiosis between flowering plants and arbuscular mycorrhizal fungi is extremely abundant in terrestrial ecosystems. In this symbiosis, obligately biotrophic fungi colonize the root of the host plants, which can benefit from these fungi by enhanced access to mineral nutrients in the soil, especially phosphorus. One of the main goals of research on this symbiosis is to find plant...

Arbuscular mycorrhizal (AM) symbiosis is generally considered to be effective in ameliorating the plant tolerance to salt stress. Unfortunately, the comprehension of the mechanisms implicated in salinity stress alleviation by AM symbiosis is far from being complete. Thus, an experiment was performed by growing durum wheat (Triticum durum Desf.) plants under salt-stress conditions to evaluate th...

The mycorrhizal symbiosis between soil fungi and plant roots is a ubiquitous mutualism that plays key roles in plant nutrition, soil health, and carbon cycling. The symbiosis evolved repeatedly and independently as multiple morphotypes [e.g., arbuscular mycorrhizae (AM), ectomycorrhizal (ECM)] in multiple fungal clades (e.g., phyla Glomeromycota, Ascomycota, Basidiomycota). The accessibility an...

Beneficial plant-microorganism interactions are widespread in nature. Among them, the symbiosis between plant roots and arbuscular mycorrhizal fungi (AMF) is of major importance, commonly improving host nutrition and tolerance against environmental and biotic challenges. Metabolic changes were observed in a well-established symbiosis between tomato and two common AMF: Rhizophagus irregularis an...

The arbuscular mycorrhizal (AM) symbiosis formed between plant roots and fungi is one of the most widespread symbiotic associations found in plants, yet our understanding of events underlying its development are limited. The recent integration of biochemical, molecular and genetic approaches into analyses of the symbiosis is providing new insights into various aspects of its development. In the...

Disruption of mycorrhizal fungi that form symbioses with local native plants is a strategy used by some invasive exotic plants for competing within their resident communities. Example invasive plants include Alliaria petiolata (garlic mustard) and Brassica nigra (black mustard), both non-mycorrhizal plants in the Family Brassicaceae. Although there is clear evidence for mycorrhizal degradation,...

BACKGROUND The stability of cooperative interactions among different species can be compromised by cheating. In the plant-mycorrhizal fungi symbiosis, a single mycorrhizal network may interact with many plants, providing the opportunity for individual plants to cheat by obtaining nutrients from the fungi without donating carbon. Here we determine whether kin selection may favour plant investmen...
