Quantitative imaging of rhizosphere pH and CO2 dynamics with planar optodes.
BACKGROUND AND AIMS Live imaging methods have become extremely important for the exploration of biological processes. In particular, non-invasive measurement techniques are key to unravelling organism-environment interactions in close-to-natural set-ups, e.g. in the highly heterogeneous and difficult-to-probe environment of plant roots: the rhizosphere. pH and CO2 concentration are the main dri...
متن کاملA novel non-invasive optical method for quantitative visualization of pH dynamics in the rhizosphere of plants.
A novel optical method for non-invasive, quantitative and high-resolution imaging of spatial and temporal pH dynamics in soils mediated by plant roots is introduced. This method overcomes present limitations of measurement of pH, mainly short-term and punctiform measurements, by recording long-term dynamics of the micro-pattern of pH in the root-soil interface without disturbance of the biologi...
متن کاملUsing system dynamics approach to identify factors affecting energy consumption and CO2 emissions in urban transport: A Case Study of Tehran
The current trend of rising energy consumption in the world has hit mankind with two major crises: first, environmental pollution, and second, the acceleration of finishing energy supplies. Energy storage and reduction of pollutants in the city plays a crucial role in the process of maintaining existing energy. Meanwhile, the transportation sector needs attention due to its importance and posit...
متن کاملOxygen dynamics in the rhizosphere of Zostera marina: A two-dimensional planar optode study
The oxygen dynamics in the rhizosphere of Zostera marina was studied by use of planar optodes. Oxygen leakage to the rhizosphere was restricted to the root tip and extended only up to ;8 mm up along the root. The oxic sediment volume around the roots increased linearly with irradiance in the interval of 0–250 mmol photons m22 s21, but the leakage rate saturated at the maximum irradiance of 500 ...
متن کاملTwo decades of chemical imaging of solutes in sediments and soils--a review.
The increasing appreciation of the small-scale (sub-mm) heterogeneity of biogeochemical processes in sediments, wetlands and soils has led to the development of several methods for high-resolution two-dimensional imaging of solute distribution in porewaters. Over the past decades, localised sampling of solutes (diffusive equilibration in thin films, diffusive gradients in thin films) followed b...
