Tracing sources of cadmium in agricultural soils: a stable isotope approach [PDF]

open access: yes, 2018
Cadmium (Cd) is a biotoxic heavy metal, which is accumulated by plants and animals and thereby enters the human food chain (Gray et al. 2003). The application of phosphate fertilisers has also resulted in the long-term accumulation of Cd in agricultural ...

Increased arbuscular mycorrhizal fungal biomass and diversity in soil under long‐term climate drying and warming

open access: yesNew Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) support critical ecosystem services including plant resource acquisition and productivity. AMF functional traits such as relative biomass investment in root vs soil colonization or drought tolerance are thought to be evolutionarily conserved within AMF lineages and might influence AMF community responses to ...

Soil-plant relationships of magnesium in selected Taranaki yellow-brown loams : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Soil Science at Massey University [PDF]

open access: yes, 1976
Best copy available.The exchangeable Mg contents of soils in the Inglewood - New Plymouth area of Taranaki are primarily determined by Mg contents of parent materials.

Long‐term effects of clear‐cutting forestry on ectomycorrhizal fungi in boreal forest

open access: yesNew Phytologist, EarlyView.
Summary Clear‐cutting is detrimental to ectomycorrhizal fungi in a short time perspective, but long‐term effects on species richness and community composition are uncertain. To evaluate ecological sustainability of rotation forestry, we examined to what extent communities similar to those in old forests develop within the time frame of a rotation ...

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

open access: yesNew Phytologist, EarlyView.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

Grassland age and local adaptation shape drought resilience across semi‐natural grassland populations

open access: yesNew Phytologist, EarlyView.
Field sampling sites and mesocosm experimental design. Summary Increasing frequency and intensity of droughts threaten grassland ecosystems. Semi‐natural grasslands vary in age from ancient to younger sites established on former arable land. While species richness and composition are known to affect drought resilience, little is known about how ...

A Truncated WRKY Protein Enhances Drought Resistance in Wild Tomatoes Through the SlWRKY16‐CIP2b‐SlSYP121 Module

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Drought stress is a major abiotic factor that severely affects plant growth and food production. Identifying drought‐resistant genes and their regulatory mechanisms is essential for mitigating the negative impacts of drought on plants. In this study, we identified a natural single nucleotide polymorphism (SNP) mutation in SlWRKY16 that is ...

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Arbuscular Mycorrhizal Fungi May Account for a Phosphorus‐Facilitation Strategy

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Mycorrhizal phosphorus (P)‐scavenging strategies are inefficient in severely P‐impoverished environments; yet many mycorrhizal species occur here. How these species acquire P and how their acquisition coordinates with root and leaf traits remain unknown.
