Open AccessMicrobial competition for phosphorus limits the CO2 response of a mature forest
The capacity for terrestrial ecosystems to sequester additional carbon (C) with rising CO2 concentrations depends on soil nutrient availability1,2. Previous evidence suggested that mature forests growing on phosp...

The fate of carbon in a mature forest under carbon dioxide enrichment
Atmospheric carbon dioxide enrichment (eCO2) can enhance plant carbon uptake and growth1–5, thereby providing an important negative feedback to climate change by slowing the rate of increase of the atmospheric CO

Flooding and prolonged drought have differential legacy impacts on soil nitrogen cycling, microbial communities and plant productivity
Extreme climate events, including flooding and prolonged drought, may establish long-lasting (legacy) effects on soil abiotic and biotic properties, potentially influencing soil N-cycling, microbial communitie...

Three years of soil respiration in a mature eucalypt woodland exposed to atmospheric CO2 enrichment
The rate of CO2 diffusion from soils to the atmosphere (soil CO2 efflux, soil respiration; Rsoil) reflects the integrated activity of roots and microbes and is among the largest fluxes of the terrestrial global C...

Impacts of waterlogging on soil nitrification and ammonia-oxidizing communities in farming system
Waterlogging may affect soil nitrification rates, resulting in changes in plant-available nitrogen (N), and hence potentially influencing crop productivity. Because nitrification is a microbially-driven proces...

Elevated CO2 does not increase eucalypt forest productivity on a low-phosphorus soil
Experimental evidence from a mature, phosphorous-limited, eucalypt forest finds that aboveground productivity was not significantly stimulated by elevated CO2. Findings suggest that this effect may be limited acr...

Open AccessPopulus trichocarpa encodes small, effector-like secreted proteins that are highly induced during mutualistic symbiosis
During symbiosis, organisms use a range of metabolic and protein-based signals to communicate. Of these protein signals, one class is defined as ‘effectors’, i.e., small secreted proteins (SSPs) that cause phe...

Open AccessRoot morphogenic pathways in Eucalyptus grandis are modified by the activity of protein arginine methyltransferases
Methylation of proteins at arginine residues, catalysed by members of the protein arginine methyltransferase (PRMT) family, is crucial for the regulation of gene transcription and for protein function in eukar...

Plant-soil interactions and nutrient availability determine the impact of elevated CO2 and temperature on cotton productivity
Elevated CO2 (CE) and temperature (TE) can not only affect crop physiology and growth but also soil nutrient availability, which could in turn influence crop response to CE and TE. However, such indirect impacts ...

Resilience of Fungal Communities to Elevated CO2
Soil filamentous fungi play a prominent role in regulating ecosystem functioning in terrestrial ecosystems. This necessitates understanding their responses to climate change drivers in order to predict how nut...

In vitro interactions between ectomycorrhizal fungi and ericaceous plants
In view of the close association between ericaceous shrubs and ectomycorrhizal trees in forest ecosystems, the interaction between ectomycorrhizal basidiomycetes and the hair roots of four typical ericoid myco...

Response of soil microbial communities to management strategies for enhancing Scots pine (Pinus sylvestris) establishment on heather (Calluna vulgaris) moorland
Active management to encourage the expansion of native pine woodland onto neighbouring moorland has been suggested as a tool to promote increases in forest area to combat climate change. Low intensity burning ...

Plant genotypic diversity does not beget root-fungal species diversity
The number of genetically distinct individuals within a community is a key component of biodiversity and yet its impact at different trophic levels, especially upon the diversity of functionally important soil...

Soil fungal communities differ in native mixed forest and adjacent Araucaria cunninghamii plantations in subtropical Australia
Commercial monoculture plantations of the native Australian Araucaria cunninghamii are common in subtropical and tropical Queensland and are generally established following clearing of native mixed forest. The co...

Does the preferential microbial colonisation of ferromagnesian minerals affect mineral weathering in soil?
Fungal activity is thought to play a direct and effective role in the breakdown and dissolution of primary minerals and in the synthesis of clay minerals in soil environments, with important consequences for p...

Changes in Fungal Community Composition in Response to Vegetational Succession During the Natural Regeneration of Cutover Peatlands
Despite the importance of peatlands as a major store of sequestered carbon and the role of fungi in releasing sequestered C, we know little about the community structure of fungi in peatlands. We investigated ...

Does carbon partitioning in ectomycorrhizal pine seedlings under elevated CO2 vary with fungal species?
Enhanced soil respiration in response to elevated atmospheric CO2 has been demonstrated, and ectomycorrhizal (ECM) fungi are of particular interest since they partition host-derived photoassimilates belowground. ...
