1998 journal article

Nitrogen-15 labeling effectiveness of two tropical legumes

PLANT AND SOIL, 200(2), 149–156.

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

author keywords: Desmodium ovalifolium; N balance; 15N methodology; N mineralization; Pueraria phaseoloides
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 journal article

Source and magnitude of ammonium generation in maize roots

PLANT PHYSIOLOGY, 118(3), 835–841.

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

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)

1997 journal article

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

Plant Science, 123(1997), 1–7.

By: R. Volk n

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)

1979 journal article

REDUCTION OF PLANT-TISSUE NITRATE TO NITRIC-OXIDE FOR MASS-SPECTROMETRIC N-15 ANALYSIS

ANALYTICAL BIOCHEMISTRY, 97(1), 131–135.

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

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 journal article

Photorespira-tory phenomena in maize: Oxygen uptake, isotope discrimination and carbon dioxide efflux

Plant Physiology, 49(2), 218.

By: R. Volk n & W. Jackson  n

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)
