The role of calcium signaling in plants: from Arabidopsis to barley
(2021-11-22)
Ca2+ is an important intracellular secondary messenger involved in many signal transduction pathways in plants. During abiotic and biotic stresses, specific Ca2+ signatures are formed within the plant ......
Die Phyllosphäre als Lebensraum für Bakterien: Mechanismen der Interaktion epiphyller Bakterien mit der pflanzlichen Kutikula
(2020-12-16)
Die Phyllosphäre stellt einen lebensfeindlichen Lebensraum dar. Jedoch gibt es epiphytisch lebende Bakterien, die diesen Lebensumständen entgegenwirken und Mechanismen entwickelt haben, in diesem kargen Lebensraum Nährstoffe ......
Molecular analysis of the plastid-targeted gene and protein (CpPTP-1) associated with desiccation tolerance in the resurrection plant Craterostigma plantagineum
(2021-01-28)
Water scarcity causes drought stress and enormous losses in agricultural production, and consequently this leads to a worldwide food crisis. Craterostigma plantagineumis one of the best studied resurrection plants that is ......
Functional Integration of Floral Plant Traits: Shape and Symmetry, Optical Signal, Reward and Reproduction in the Angiosperm Flower
(2020-05-12)
Pollination syndromes represent groups of floral phenotypes that have originated and diversified in interaction with biotic and abiotic pollen vectors. Plant trait pattern that constitute respective syndromes have been ...
Characterization of Enzymes Involved in Lipid Biosynthesis from the Photosynthetic Bacteria Synechocystis PCC6803 and Blastochloris viridis
(2020-05-05)
Cyanobacteria are unicellular prokaryotic algae that perform oxidative photosynthesis similar to plants. The cells harbour thylakoid membranes composed of lipids related to those of chloroplasts in plants, to accommodate ...
JAR1-mediated JA-Ile accumulation: a mechanism towards drought stress resistance in Arabidopsis thaliana
(2021-11-26)
In the present work, the regulatory capacity of biologically active jasmonate, jasmonyl-isoleucine (JA-Ile), under normal and progressive drought stress conditions throughout a plant’s life-cycle was investigated. To alter ......
The mechanisms of stress memory responses and translational regulation during dehydration and rehydration in the resurrection plant Craterostigma plantagineum
(2020-05-25)
Dehydration stress is one of the major environmental factors affecting the survival rate and productivity of plants. Currently, many dehydration-induced genes and some dehydration-related protective mechanisms desiccation ......
The chloroplast calcium sensor protein CAS is part of the STN7/STN8 kinase phosphorylation network and is required for photoacclimation
(2020-03-10)
In the present work, the phosphorylation profile of the chloroplast-localized Calcium Sensing Receptor (CAS) from A. thaliana was investigated and it could be shown that CAS is a target of multiple protein kinases acting ......
Evolution of floral organisation and architecture in Boraginales and Geraniales
(2020-08-13)
In this thesis, development, morphology and anatomy of structures from selected taxa from the Gera- niales and Boraginales are studied. Furthermore, the integration of structures such as stamen-corolla tube modifications ......
Molecular and biochemical studies of the Craterostigma plantagineum cell wall during dehydration and rehydration
(2020-02-17)
Craterostigma plantagineum belongs to the desiccation tolerant angiosperm plants. Upon dehydration leaves fold and the cells shrink which is reversed during rehydration. To understand this process changes in cell wall ......
