Feedback with soil biota contributes to plant rarity and invasiveness in communitiesJohn N Klironomos
Department of Botany, University of Guelph, Guelph, Ontario, Canada N1G 2W1

Mycorrhiza 17:175-83. 2007..Saturated soils of calcareous fens contain many infective AMF propagules and the abundance and diversity of AMF inoculum is patchy over small spatial scales...
Invasive plant suppresses the growth of native tree seedlings by disrupting belowground mutualismsKristina A Stinson
Harvard Forest, Harvard University, Petersham, Massachusetts, USA
PLoS Biol 4:e140. 2006..Our results elucidate an indirect mechanism by which invasive plants can impact native flora, and may help explain how this plant successfully invades relatively undisturbed forest habitat...

Mycorrhiza 12:181-4. 2002..It is unclear why there is such a difference among the fungi in inoculum types. Future research should examine differences in the anatomy and physiology to discern a mechanism for such differences in life-history strategies...
Abrupt rise in atmospheric CO2 overestimates community response in a model plant-soil systemJohn N Klironomos
Department of Integrative Biology, University of Guelph, Guelph, Ontario N1G 2W1, Canada

Mycorrhizal symbiosis stimulates endoreduplication in angiospermsL D Bainard
Integrative Biology, University of Guelph, Guelph, Ontario, Canada N1G 2W1
Plant Cell Environ 34:1577-85. 2011..This work indicates that colonization by symbiotic fungi involves a mechanism to increase nuclear DNA content in roots across many angiosperm groups and is likely linked to increased metabolism and protein production...
Real-time polymerase chain reaction quantification of the transgenes for roundup ready corn and roundup ready soybean in soil samplesS Lerat
