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 کاملContinuum of root-fungal symbioses for plant nutrition.
Plants accommodate a specific microbiota on and in their roots that, similar to the microbial communities in human or animal guts, supports the host in nutrient acquisition (1). Beneficial associations with fungi are widespread in the plant kingdom and probably best known are so-called mycorrhizal symbioses (Fig. 1), which are formed between soil fungi and ∼90% of land plants (2). In these part...
متن کاملRoot Traits and Phenotyping Strategies for Plant Improvement
Roots are crucial for nutrient and water acquisition and can be targeted to enhance plant productivity under a broad range of growing conditions. A current challenge for plant breeding is the limited ability to phenotype and select for desirable root characteristics due to their underground location. Plant breeding efforts aimed at modifying root traits can result in novel, more stress-tolerant...
متن کاملNetwork modules and hubs in plant-root fungal biomes.
Terrestrial plants host phylogenetically and functionally diverse groups of below-ground microbes, whose community structure controls plant growth/survival in both natural and agricultural ecosystems. Therefore, understanding the processes by which whole root-associated microbiomes are organized is one of the major challenges in ecology and plant science. We here report that diverse root-associ...
متن کاملBacterial and fungal colonization and decomposition of submerged plant litter: consequences for biogenic silica dissolution
We studied bacterial and fungal colonization of submerged plant litter, using a known Si-accumulator (Equisetum arvense), in experimental microcosms during one month. We specifically addressed the microbial decomposer role concerning biogenic silica (bSiO2) dissolution from the degrading litter. To vary the rates and level of microbial colonization, the litter was combined with a range of miner...
