Microbial Mineral Weathering for Nutrient Acquisition Releases Arsenic [PDF]

Applied and Environmental Microbiology, 2009
ABSTRACT Tens of millions of people in Southeast Asia drink groundwater contaminated with naturally occurring arsenic. How arsenic is released from the sediment into the water remains poorly understood. Here, we show in laboratory experiments that phosphate-limited cells of Burkholderia fungorum mobilize ...

Breeding Milestones Correspond with Changes to Wheat Rhizosphere Biogeochemistry That Affect P Acquisition

Agronomy, 2023
Breeding wheat (Triticum aestivum L.) has resulted in small gains in improved nutrient acquisition and use as numerous traits are involved. In this study, we evaluated the impact of breeding on P-acquisition and identified both plant and soil variables ...

Food for thought: how nutrients regulate root system architecture [PDF]

, 2017
The spatial arrangement of the plant root system (root system architecture, RSA) is very sensitive to edaphic and endogenous signals that report on the nutrient status of soil and plant.

Myxobacterial Predation: A Standardised Lawn Predation Assay Highlights Strains with Unusually Efficient Predatory Activity

Microorganisms, 2023
Myxobacteria prey upon a broad range of microorganisms. Lawn assays are commonly used to quantify myxobacterial predation—myxobacterial suspensions are spotted onto prey lawns, and monitored via spot expansion.

Responses of Microbial Nutrient Acquisition to Depth of Tillage and Incorporation of Straw in a Chinese Mollisol

Frontiers in Environmental Science, 2021
Tillage and straw incorporation are important agricultural practices that can break the plow layer and improve Mollisol fertility. The effect of these practices on the limitation of resources for soil microorganisms, however, is unclear. We established a

Phosphorus limitation of aboveground production in northern hardwood forests [PDF]

, 2018
Forest productivity on glacially derived soils with weatherable phosphorus (P) is expected to be limited by nitrogen (N), according to theories of long-term ecosystem development.

Satellite remote sensing reveals a positive impact of living oyster reefs on microalgal biofilm development [PDF]

, 2018
Satellite remote sensing (RS) is routinely used for the large-scale monitoring of microphytobenthos (MPB) biomass in intertidal mudflats and has greatly improved our knowledge of MPB spatio-temporal variability and its potential drivers.

Impact of different zinc concentrations on growth, yield, fruit quality, and nutrient acquisition traits of tomato (Lycopersicon esculentum L.) grown under salinity stress [PDF]

Archives of Biological Sciences
Salinity stress affects plant growth, development, nutrient uptake, and yield. Applications of micronutrients, specifically zinc (Zn), can mitigate the harmful consequences of salt stress.

Mechanical Impedance and Nutrient Acquisition in Rice

Plant and Soil, 2006
The aim of this work was to examine the effect of mechanical impedance on nutrient acquisition and gene expression in rice (Oryza sativa L.). Roots were mechanically impeded in a sand-core apparatus to vary impedance independently of aeration and water status.
