Abstract The active bacterial rhizobiomes and root exudate profiles of phytometers six plant species growing in central European temperate grassland communities were investigated three regions located up to 700 km apart, across diverse edaphic conditions along a strong land use gradient. recruitment process from bulk soil was identified as the major direct driver composition rhizosphere communities. Unexpectedly, effect properties, particularly texture, water content, type, strongly...
Abstract Plants exude a diverse cocktail of metabolites into the soil as response to exogenous and endogenous factors. So far, root exudates have mainly been studied under artificial conditions due methodological difficulties. In this study, each five perennial grass forb species were investigated for polar semi-polar in field conditions. Metabolite collection untargeted profiling approaches combined with novel classification method allowed designation 182 metabolites. The composition exuded...
Primary and secondary metabolites exuded by plant roots have mainly been studied under laboratory conditions, while knowledge of root exudate patterns plants growing in natural communities is very limited. Focusing on ten common European grassland species, we asked to which degree metabolite compositions are specific species or growth forms (forbs grasses), depend environments local neighbourhoods, reflect traditional functional traits. Root exudates were collected field conditions analysed...
Abstract Questions To what extent is trait variation in grasses and forbs driven by land‐use intensity, climate, soil conditions plant diversity of the local neighbourhood? Do grass forb species differ degree intraspecific variation? Location Managed grasslands three regions Germany. Methods Using a phytometer approach, we raised 20 common European grassland (ten ten grasses) planted them into 54 plots different types (pasture, meadow, mown pasture). After 1 yr field, measured above‐...
In the rhizosphere, plants are exposed to a multitude of different biotic and abiotic factors, which they respond by exuding wide range secondary root metabolites. So far, it has been unknown degree exudate composition is species-specific affected land use, local impact neighborhood under field conditions. this study, exudates 10 common grassland species were analyzed, each five forbs grasses, in German Biodiversity Exploratories using combined phytometer untargeted liquid...
Abstract Plant functional traits are widely used to predict community productivity. However, they rarely individual plant performance in grasslands. To assess the relative importance of compared environment, we planted seedlings 20 common grassland species as phytometers into existing communities varying land‐use intensity. After 1 year, dug out plants and assessed root, leaf, aboveground biomass, measure performance. Furthermore, determined all growing their local neighborhood. Neighborhood...
