1998 article

Nitrogen-15 labeling effectiveness of two tropical legumes

Glasener, K. M., Wagger, M. G., MacKown, C. T., & Volk, R. J. (1998, March 1). Plant and Soil.

By: K. Glasener, M. Wagger n, C. MacKown* & R. Volk n

author keywords: Desmodium ovalifolium; N balance; 15N methodology; N mineralization; Pueraria phaseoloides
topics (OpenAlex): Soil Carbon and Nitrogen Dynamics; Soil and Water Nutrient Dynamics; Plant nutrient uptake and metabolism
TL;DR: Results demonstrate that 15N foliar application to legumes is an effective method for labeling, resulting in atom% excess 15N levels and 15N recoveries comparable to those reported with the more traditional soil-labeling approach. (via Semantic Scholar)

1998 article

Source and Magnitude of Ammonium Generation in Maize Roots

Feng, J., Volk, R. J., & Jackson, W. A. (1998, November 1). PLANT PHYSIOLOGY.

By: J. Feng  n, R. Volk n & W. Jackson n

topics (OpenAlex): Plant nutrient uptake and metabolism; Phosphorus and nutrient management; Soil Carbon and Nitrogen Dynamics
TL;DR: Observations reveal that catabolism of soluble organic N, not protein N, is the primary source of endogenous NH4+ generation in maize roots, and 14NH4+ efflux continues throughout the 3-d period. (via Semantic Scholar)

Unidirectional fluxes of nitrate into and out of maize roots: measurement and regulation by prior nitrate nutrition

Volk, R. J. (1997, March 1). Plant Science.

By: R. Volk n

topics (OpenAlex): Plant nutrient uptake and metabolism; Legume Nitrogen Fixing Symbiosis; Phosphorus and nutrient management
TL;DR: A method for rapid assay of concurrent fluxes of nitrate into and out of intact plant roots has been developed and net nitrate uptake was 26–30% higher at a root nitrate concentration of 8.2 μmol/g fw than at the lower and higher concentrations. (via Semantic Scholar)

Reduction of plant tissue nitrate to nitric oxide for mass spectrometric 15N analysis

Volk, R. J., Pearson, C. J., & Jackson, W. A. (1979, August 1). Analytical Biochemistry.

By: R. Volk n, C. Pearson* & W. Jackson  n

MeSH headings : Mass Spectrometry; Nitrates / analysis; Nitric Oxide / analysis; Oxidation-Reduction; Plants / analysis; Zea mays / analysis
topics (OpenAlex): Isotope Analysis in Ecology; Mass Spectrometry Techniques and Applications; Advanced Chemical Sensor Technologies
TL;DR: A procedure based on that of Van Slyke and LoMonte is described for the mass spectrometric analysis of 15 N in nitrate extracted from plant tissue, unaffected by reduced nitrogen compounds which are present in plant tissue extracts. (via Semantic Scholar)

1972 article

Photorespiratory Phenomena in Maize

Volk, R. J., & Jackson, W. A. (1972, February 1). PLANT PHYSIOLOGY.

By: R. Volk n & W. Jackson  n

topics (OpenAlex): Plant responses to elevated CO2; Photosynthetic Processes and Mechanisms; Plant Water Relations and Carbon Dynamics
TL;DR: It is concluded that a finite photorespiratory process occurs in maize and that the CO(2) generated thereby is efficiently recycled, suggesting continual (13)C enrichment of the photorepiratory substrate. (via Semantic Scholar)
