Rhizosphere carbon flow measurement and implications: from isotopes to reporter genes

  author={K. K. Killham and Catrin Yeomans},
  journal={Plant and Soil},
Despite the fundamental importance of rhizosphere C-flow in managed and natural systems, reliable measurement/resolution of C-flow and assessment of its consequences have largely remained elusive to soil biologists. Techniques involving both radioactive (14C) and stable (13C) isotopes of carbon have made some progress in terms of studying rhizosphere C-flow. Pulse-chase techniques have been used effectively to study dynamics of C-transfer to the rhizosphere and rhizosphere microbial biomass… CONTINUE READING
