Ectomycorrhizal colonization slows root decomposition: the post-mortem fungal legacy.
The amount of carbon plants allocate to mycorrhizal symbionts exceeds that emitted by human activity annually. Senescent ectomycorrhizal roots represent a large input of carbon into soils, but their fate remains unknown. Here, we present the surprising result that, despite much higher nitrogen concentrations, roots colonized by ectomycorrhizal (EM) fungi lost only one-third as much carbon as no...
متن کاملRoot colonization dynamics of two ectomycorrhizal fungi of contrasting life history strategies are mediated by addition of organic nutrient patches
• Here we investigated whether root colonization dynamics of ectomycorrhizal fungi (EMF) of contrasting life history strategies (i.e. early vs late successional dominants) were affected by resource availability, as mediated either directly via the soil, or indirectly via host nutrition. • In a two phase experiment, Pinus muricata seedlings were co-inoculated with spores of early ( Rhizopogon oc...
متن کاملSeasonal and Site Effects on Oak Fine Root Production and Ectomycorrhizal Colonization in California Oak Woodland
At three sites in a blue oak woodland in northeast California, we studied seasonal patterns of blue oak (Quercus douglasii Hook and Arn.) fine root (< 2 mm diameter) production and ectomycorrhizal (ECM) colonization using root ingrowth cores. In a short-term study, ingrowth cores were installed and harvested in 3-month intervals for one year. Oak fine root production was lower in fall and winte...
متن کاملVolatile signalling by sesquiterpenes from ectomycorrhizal fungi reprogrammes root architecture
The mutualistic association of roots with ectomycorrhizal fungi promotes plant health and is a hallmark of boreal and temperate forests worldwide. In the pre-colonization phase, before direct contact, lateral root (LR) production is massively stimulated, yet little is known about the signals exchanged during this step. Here, we identify sesquiterpenes (SQTs) as biologically active agents emitte...
متن کاملFurther root colonization by arbuscular mycorrhizal fungi in already mycorrhizal plants is suppressed after a critical level of root colonization.
An established arbuscular mycorrhizal symbiosis suppresses further mycorrhization. It is not clear whether the observed suppressional effect is linked with the level of root colonization or not. In the present work we studied the effect of the degree of root colonization by the arbuscular mycorrhizal fungus Glomus mosseae on further root colonization by G. mosseae. At different time points barl...
