Networks of power and influence: the role of mycorrhizal mycelium in controlling plant communities and agroecosystem functioning (2004, methodology): “These pioneering measurements were a major advance, but the values appear to have underestimated the true C cost of AM mycelia, in part because maximum C allocation to external mycelium occurs within 24 h after pulse labelling of shoots (Johnson et al. 2002a; Staddon et al. 2003).”
Response of mycorrhizal, rhizosphere and soil basal respiration to temperature and photosynthesis in a barley field (2007, background): “…to severe mycorrhizal hyphae with the subsequent reductions in respiration rates as well as the tracing of isotopes from labeled plants to the inside of the mesh bound cores have demonstrated that these root-free compartments are effectively colonized by mycorrhiza (Johnson et al., 2001, 2002a, b).”
Soil respiration fluxes in relation to photosynthetic activity in broad-leaf and needle-leaf forest stands (2008, methodology): “Evidence for mycorrhizal in-growth can be found in previous studies, e.g. the movement of carbon from the plant to the inside of 35 mm mesh soil cores has been successfully traced with the use of isotope measurements (Johnson et al., 2002 and references therein).”
Evaluation of methods to estimate production, biomass and turnover of ectomycorrhizal mycelium in forests soils : A review (2013, background): “One advantage with such cores is that they can be rotated regularly to detach fungal in-growth in order to function as controls with similar soil physical conditions but no, or little, fungal in-growth (Johnson et al., 2001, 2002a,b).”
Community shifts and carbon translocation within metabolically-active rhizosphere microorganisms in grasslands under elevated CO 2 (2007, background): “Recent in-situ studies using PLFA-based SIP by 13C-CO2 pulse-labeling have also reported a much faster incorporation of rhizosphere-C into fungal (Treonis et al., 2004) as well as AMF biomass (Johnson et al., 2002; Olsson and Johnson, 2005) compared to bacterial biomass (Treonis et al., 2004).”
Facilitated legume nodulation, phosphate uptake and nitrogen transfer by arbuscular inoculation in an upland rice and mung bean intercropping system (2009, background): “This phenomenon may suggest that the establishment of AMF mycelia needs a sequestration of carbon of leaf photosynthates relatively more from rice than from mung bean (Johnson et al. 2002a; Johnson et al. 2002b ).”
Soil temperature affects carbon allocation within arbuscular mycorrhizal networks and carbon transport from plant to fungus (2008, background): “Rapid movement of 13C from plants through hyphae has been shown in other pulse studies (Johnson et al., 2002a).”
