Poplar Responses to Nutrient Deficiency and Drought as Affected by Different Ectomycorrhizal Fungal Species
(2025-02-14)Nutrient imbalances and drought are challenges the world’s forests are currently facing due to massively changing environmental conditions. In European forests, phosphorus (P) nutrition is declining due to increasing ... -
Mycorrhizal mediation of nutrient distribution and stress responses in beech and conifer mixtures
(2024-10-14)With global warming, drought is a rising concern for forests worldwide. In Central Europe, drought has caused severe diebacks of Norway spruce (Picea abies), the most common and economically relevant tree species. ... -
Influence of mycorrhiza on nutrient physiology of trees in mixed and mono-specific stands along climatic and land use gradients
(2022-05-25)Global change drivers such as climate change, land-use change, anthropogenic N deposition, deteriorating P nutrition and other calamities jeopardize temperate forest ecosystem functions. Essential components for the ... -
Physiological, morphological and molecular acclimation of Populus spp. to high salinity
(2022-03-25)Salinization of terrestrial land is a global environmental problem, causing loss in soil fertility. Cultivation of salt tolerant species counteracts soil degradation and ensures productive utilization of salt-affected ... -
Ecophysiological field studies of phosphorus nutrition of beech (Fagus sylvatica)
(2021-10-19)Phosphorus (P) is an essential element for plant nutrition because it is required for many essential biomolecules such as nucleotides, membrane lipids and ATP. Plants take up P as inorganic phosphate (Pi) from soil solutions. ... -
Assembly of root-associated fungi in different soil layers and nitrogen uptake by ectomycorrhizae in temperate forests
(2021-07-30)Fungi are a remarkably highly diverse group of organisms on Earth, playing a pivotal role in ecosystem functioning. Belowground, they act as decomposers, pathogens or symbionts. Members of these functional categories are ... -
Modification of lipid biosynthesis in Populus x canescens and characterization of transgenic lines
(2021-04-30)Lipid-derived hydrocarbons have many important tasks in land plants. They prevent uncontrolled water loss as constituents of the hydrophobic properties of the cuticula. Another important task of lipid-derived hydrocarbons ... -
Compositional and functional shifts in belowground fungal communities in tropical land-use systems
(2020-06-23)Tropical low-land rainforests are one of the most diverse ecosystems in the world and provide valuable ecosystem services such as climate change mitigation. They are immensely threatened by expanding human land-use. ... -
Diversity and function of root-associated fungal communities in relation to nitrogen nutrition in temperate forests
(2019-01-29)Ectomycorrhizal fungi form symbiotic association with roots of a variety of plant species. They provide plants with nutrients in exchange of photosynthetic carbohydrates. In natural ecosystems, plants form associations not ... -
Wood anatomy and cytokinin-related responses in poplar (Populus sp.) under environmental stress
(2018-02-09)Woody plants like poplar are of great importance as a second generation bioenergy crop. However, wood formation is dynamic and strongly affected by exogenous factors such as drought or seasonality, and endogenous factors. ... -
Impact of Rain Forest Transformation on Roots and Functional Diversity of Root-Associated Fungal Communities
(2017-12-07)Tropical rain forests are representing biodiversity hotspots, but their species richness is threatened by human driven land use changes. Between 1990 and 2015 most of the global deforestation of about 129 million hectares ... -
Phosphorus nutrition of poplar
(2017-05-29)Phosphorus (P) is a major plant nutrient required for the biosynthesis of nucleic acids, nucleotides, membrane lipids and metabolites such as organic esters. P further plays a role in enzyme regulation by phosphorylation. ... -
Drought stress response of tetraploid hybrid aspen (Populus tremula L. x P. tremuloides Michx.) of protoplast fusion experiments)
(2016-05-17)Poplar (Populus) varieties that are planted in short rotation coppice are supposed to show high biomass production, the ability to propagate via stem cuttings but also drought tolerance because drought is a very important ... -
Kohlenstoff- und Stickstofftransport in temperaten Laubbäumen und ihren Mykorrhizen
(2016-05-02)In the present work was shown that Transfer of Carbon and Nitrogen was detectable from leaves to associated mycorrhizas in different broadleaf tree species. For that results of different field and laborary Experiments with ... -
Functional diversity of mycorrhiza in relation to land-use changes and ecosystem functions
(2016-02-19)Managing forest ecosystems has a long tradition in Germany. However, the influence of this intervention on the most important symbiosis partners of the trees, mycorrhizal fungi, is poorly understood. The fungal partner ... -
Community structure of Arbuscular Mycorrhizal Fungi in temperate grassland and tropical land-use systems
(2015-08-31)Most plants in temperate and tropical regions form symbiotic association with mycorrhizal fungi. Studies on mutualistic association of mycorrhiza focus mainly on temperate regions of the world, whereas little information ... -
Communication between mycorrhizal fungi and poplar
(2015-03-18)Volatile organic compounds (VOCs) have multiple functions in the atmosphere and biosphere. VOCs are involved in above- and belowground biotic interactions. For example, VOCs released by microbes have the potential to ... -
Mykorrhizafunktion bei der Konkurrenz um Stickstoff in Kalkbuchenwäldern
(2014-04-16)Beech (Fagus sylvatica L.) is a very important tree species in Central Europe due to its economical value and ecological services. Beech forests are often growing on soils, where nitrogen is the growth limiting factor. ... -
Funktionelle Charakterisierung von apoplastischen Proteinen in Brassica napus und Arabidopsis thaliana nach Infektion mit Verticillium longisporum
(2011-06-24)Verticillium longisporum is a soil-borne pathogenic fungus which is restricted to the family of Brassicaceae. V. longisporum is a vascular pathogen which colonizes the xylem of its host ... -
