Common mycorrhizal networks amplify size inequality in Andropogon gerardii monocultures.
Arbuscular mycorrhizal fungi can interconnect plant root systems through hyphal common mycorrhizal networks, which may influence the distribution of limiting mineral nutrients among interconnected individuals, potentially affecting competition and consequent size inequality. Using a microcosm model system, we investigated whether the members of Andropogon gerardii monocultures compete via commo...
متن کاملInterplant Communication of Tomato Plants through Underground Common Mycorrhizal Networks
Plants can defend themselves to pathogen and herbivore attack by responding to chemical signals that are emitted by attacked plants. It is well established that such signals can be transferred through the air. In theory, plants can also communicate with each other through underground common mycorrhizal networks (CMNs) that interconnect roots of multiple plants. However, until now research focus...
متن کاملRole of arbuscular mycorrhizal fungi in alleviation of Zn phytotoxicity and mineral nutrition of host plants
There is increasing interest worldwide in the maintenance of soil quality and remediation strategies for management of soils contaminated with pollutants including heavy metals. The protective effects of arbuscular mycorrhizas on host plants under conditions of Zn contamination have raised the prospect of utilizing the mutualistic association in soil revegetation programmes, and consequently re...
متن کاملPreferential allocation to beneficial symbiont with spatial structure maintains mycorrhizal mutualism.
Mutualisms, beneficial interactions between species, are expected to be unstable because delivery of benefit likely involves fitness costs and selection should favour partners that deliver less benefit. Yet, mutualisms are common and persistent, even in the largely promiscuous associations between plants and soil microorganisms such as arbuscular mycorrhizal fungi. In two different systems, we ...
متن کاملLimited carbon and mineral nutrient gain from mycorrhizal fungi by adult Australian orchids.
PREMISE OF THE STUDY In addition to autotrophic and fully mycoheterotrophic representatives, the orchid family comprises species that at maturity obtain C and N partially from fungal sources. These partial mycoheterotrophs are often associated with fungi that simultaneously form ectomycorrhizas with trees. This study investigates mycorrhizal nutrition for orchids from the southwestern Australia...
