Deep influence of soil microbes.
A single gram of soil is said to contain more than 8 billion bacterial cells, representing up to 50,000 different species1. These microorganisms play important roles, from tweaking how plants interact with their surroundings to influencing the chemical composition of the environment2. Now, the increased affordability of DNA sequencing technologies has enabled scientists to gain a deeper underst...
متن کاملThe role of soil microbes in plant sulphur nutrition.
Chemical and spectroscopic studies have shown that in agricultural soils most of the soil sulphur (>95%) is present as sulphate esters or as carbon-bonded sulphur (sulphonates or amino acid sulphur), rather than inorganic sulphate. Plant sulphur nutrition depends primarily on the uptake of inorganic sulphate. However, recent research has demonstrated that the sulphate ester and sulphonate-pools...
متن کاملSpatial Heterogeneity in Soil Microbes Alters Outcomes of Plant Competition
Plant species vary greatly in their responsiveness to nutritional soil mutualists, such as mycorrhizal fungi and rhizobia, and this responsiveness is associated with a trade-off in allocation to root structures for resource uptake. As a result, the outcome of plant competition can change with the density of mutualists, with microbe-responsive plant species having high competitive ability when m...
متن کاملIdentification of Soil Microbes Capable of Utilizing Cellobiosan
Approximately 100 million tons of anhydrosugars, such as levoglucosan and cellobiosan, are produced through biomass burning every year. These sugars are also produced through fast pyrolysis, the controlled thermal depolymerization of biomass. While the microbial pathways associated with levoglucosan utilization have been characterized, there is little known about cellobiosan utilization. Here w...
متن کاملSoil microbes regulate ecosystem productivity and maintain species diversity.
One of the major goals in ecology is to determine the mechanisms that drive the asymptotic increase in ecosystem productivity with plant species diversity. Niche complementarity, the current paradigm for the asymptotic diversity-productivity pattern, posits that the addition of species to a community increases productivity because each species specializes on different resources and thus can mor...
