Evaluating a Collection of Agronomic Traits to Better Understand the Importance of Epistasis and Epistasis by Environment Interaction in Maize.
(2024-04-05)Maize, a key cereal crop, stands alongside wheat and rice in global importance. Its domestication from teosinte in southern Mexico 10,000 years ago marked a turning point in human agriculture. Over the centuries, maize has ... -
Auswirkung von Bodenbearbeitungen auf den Nährstoffhaushalt von Waldböden sowie den Erfolg von Eichenkulturen
(2024-04-05)Site preparation in forests has received criticism for potentially reducing site produc-tivity due to soil compaction and nutrient losses. Nontheless, from a practical perspec-tive, site preparation is an essential factor ... -
Vergleich von stillgelegten und bewirtschafteten Wäldern anhand von zwei Fallbeispielen in Brandenburg
(2024-04-02)Forests can provide a wide range of ecosystem services. However, not all ecosystem services can be maximized at the same time, which can lead to conflicting objectives. For example, objectives range from maximizing the ... -
Exploiting the Disulfide/Thiol Switch for Photoinduced Proton-Coupled Multielectron Transfer Reactivity
(2024-03-27)Energy storage and efficient release has become a pivotal issue for our society relying progressively on renewable energy sources. The dichotomy between harvesting the sun’s energy in daylight hours, and requiring it the ... -
Changes in Microbial Resources and Trophic Niches of Microarthropods in Forest Ecosystems with Elevation
(2024-03-27)Mountain forests play a major role for biodiversity conservation, carbon storage and hydrological cycling. Therefore, understanding different components of mountain forest ecosystems is essential to predict potential ... -
Holocene vegetation and environmental changes with a focus on peat ecosystems in southwestern and northeastern Amazonia
(2024-03-27)Amazon rainforests are well-known for playing a significant role in the climate, hydrological cycle, and biodiversity on earth. Recent investigations found that Amazonia may contain the largest peat carbon (C) stock in the ... -
Characterization of testosterone and androgen receptor action in human and rhesus macaque heart muscle cells
(2024-03-26)Androgens are sex steroid hormones that influence various processes in reproductive tissues and peripheral organs. Their lipophilic nature enables free diffusion through the plasma membrane. In the cytoplasm, testosterone ... -
A novel rRNA quality control function for Npl3 in Saccharomyces cerevisiae
(2024-03-25)In all domains of life, ribosomes are essential complexes that are the sole source for protein synthesis. Ribosome biosynthesis, the most energy-consuming process in a cell, has to be tightly regulated. Misregulation ... -
Investigation of OPA1 in Mitochondrial Dynamics and Ultrastructure
(2024-03-21)Mitochondria are highly dynamic organelles with a complex ultrastructure. The mitochondrial inner membrane (MIM) is folded into cristae in which oxidative phosphorylation, a process to generate energy for the cell, takes ... -
Characterization of the molecular interaction between α-synuclein and prion protein
(2024-03-21)The interaction between α-synuclein (aSyn) and prion protein (PrP) has been implicated in the pathogenesis of synucleinopathies. However, the nature of this interaction remains poorly understood. Here, we employed a ... -
Investigation into gene regulatory networks governing the development and maintenance of the planarian reproductive system
(2024-03-20)Regulation of gene expression is a fundamental mechanism allowing the existence of complex living systems. This regulation takes shape in the form of hierarchical gene regulatory networks (GRNs), culminating in the binding ... -
Assessment of the toxicity of inorganic and organic pollutants using the benthic alga Closterium ehrenbergii
(2024-03-20)In this thesis, Closterium ehrenbergii was selected as test species for the assessment of the toxicity of environmentally relevant pollutants towards a representative of benthic algae. Therefore, a miniaturized bioassay ... -
Sustainable Ruthenium- and Rhodium-Catalyzed C−H Activations with Photochemistry and Electrochemistry
(2024-03-18)Cross-coupling chemistry stands out as a fundamental tool in synthetic organic chemistry for forging C‒C and C‒Het bonds. However, the necessity for substrate prefunctionalization imposes significant sustainability challenges ... -
Towards an Effective Synthesis of Functionalized Heptacyclo[6.6.0.02,6.03,13.04,11.05,9.010,14]tetradecane
(2024-03-14)A reassessment of the Rh-catalyzed dimerization of norbornadiene to generate heptacyclo[6.6.0.02,6.03,13.04,11.05,9.010,14]tetradecane (HCTD), a carbocyclic cage compound, has been conducted introducing novel π-acceptor ... -
Coupled dynamics of the spread of COVID-19, interventions and human behaviour
(2024-03-14)The COVID-19 pandemic has presented an unprecedented challenge to global health, prompting a need for comprehensive research into the coupled dynamics of virus spread, intervention strategies, and human behavior. This ... -
The prothoracic repellent glands of stick and leaf insects: Reconstructing the morphological and chemical evolution of an elaborate arthropod defensive system
(2024-03-11)Stick and leaf insects (Phasmatodea) form a diverse lineage of large herbivorous arthropods inhabiting predominantly tropical and subtropical regions. These insects are well known for their impressing camouflage capabilities, ... -
The complex formation of RNase P and RNase MRP in Saccharomyces cerevisiae
