CarotPhyte: Exploring the evolutionary roots for the biosynthesis of apocarotenoids and their role as signals in plastid-mediated stress response in streptophyte algae
(2024-10-18)Plant terrestrialization came with enormous multidimensional consequences that shaped planet earth. This terraforming event that occurred about 550 MYA goes back to a single progenitor. Elucidating important facilitators ... -
Identification of novel rate-limiting components in Arabidopsis cell entry control against non-adapted fungal pathogens
(2024-09-27)Cell entry into host cells represents a crucial step during pathogenesis of fungal phytopathogens. However, plants have evolved an effective cell entry control mechanism to block a majority of intruders at the front line. ... -
Characterization of abundant unknown proteins that participate in the control of tRNA maturation and fatty acid acquisition in Bacillus subtilis
(2024-07-23)Despite tremendous advances in sequencing and other state-of-the-art technologies, unknown proteins are present in virtually all living organisms. Even though Bacillus subtilis is one of the most extensively annotated model ... -
Functional Annotation of Gretchen Hagen 3 Enzymes
(2024-07-05)Plants employ a multitude of phytohormones to regulate all aspects of their physiology ranging from their development to specific, environment-dependent responses to threats and other cues. The integration of all these ... -
Functional characterization of protease inhibitors involved in induced systemic defenses in poplar
(2024-02-05)Plants are constantly challenged with biotic stresses. Stresses are gaining importance due to climate change, where extended periods of warmer conditions are expected globally. Extended warmer temperatures also mean longer ... -
Functional characterization of Arabidopsis thaliana CC-type glutaredoxin ROXY9
(2023-07-10)Glutaredoxins are small proteins with a conserved thioredoxin fold. This fold allows for two functions, depending on the sequence of the active site. Class I glutaredoxins, which are characterized by a CPYC motif, show ... -
Validation of novel protein-protein interactions in Bacillus subtilis
(2023-01-12)Protein-protein interactions are the basis for many biological processes in the cell. Understanding these interactions is crucial for the general analysis of how the cell functions and the potential identification of ... -
Protein Interactions in minimal cells
(2022-05-18)Minimal cells are used to model and understand life’s complex processes. The most essential processes of life are thought to include cell replication, energy metabolism and genome maintenance. However, construction of a ... -
Sphingolipid biosynthesis in Physcomitrella patens
(2021-06-28)The complex sphingolipid classes glycosylceramides (GlcCers) and glycosyl inositolphosphorylceramides (GIPCs) are essential membrane components in plant cells. However, the regulation of their synthesis and their distinct ... -
Characterization of Acyltransferases in Neutral Lipid Synthesis
(2021-04-23)Wax ester (WE) are neutral lipids, which consist of a fatty acid and a fatty alcohol moiety connected by an ester bond. WE are synthesized via two reactions from acyl-coenzyme A (CoA)/acyl carrier protein (ACP) substrates. ... -
The role of plasma membrane lipids in plant stresses adaptation
(2021-01-19)Lipids are essential components of cellular membranes, which constitute not only the physical platforms that harbor the membrane proteins, but also the biochemical interfaces where the exchange of biomolecules, the ... -
Function of Cuticular Waxes in Plant Response to Wounding
(2019-08-27)Neutral lipids, such as triacylglycerol (TAG) and wax are essential metabolites for plants. TAG is the most abundant storage compound in all eukaryotes. It plays an important role in plant germination but also in lipid ... -
Biogenesis of Lipid Bodies in Lobosphaera incisa
(2017-02-28)Microalgae hold great promise with regards to the production of valuable products such as PUFAs and biofuel. They are a highly interesting group of organisms for investigating lipid metabolism and while some insight has ... -
Function of the α/β-hydrolase fold family proteins Pummelig (CG1882) and Hormone-sensitive lipase in the Drosophila melanogaster lipid metabolism
(2016-09-30)To maintain energy homeostasis, all organisms need to adjust the generation and mobilization of their energy stores. The key molecules for energy storage are neutral lipids, mainly triacylglycerides (TAGs), which accumulate ... -
Structure-function relationships in wax producing enzymes
(2016-05-12)Wax esters (WEs) are esters of fatty acids and fatty alcohols. They can cover a broad range of physical properties, which makes them especially interesting for industrial applications, including additives in cosmetics and ... -
Analyse der Jasmonoyl-Isoleucin-unabhängigen Funktion des Jasmonat-Rezeptors CORONATINE INSENSITIVE1 in Wurzeln von Arabidopsis thaliana
