Host Specificity, Negative Feedbacks, and Pathogen Defense in the Plant Phyllosphere Microbiome
… conditions using wheat plants and the fungal pathogen Fusarium graminearum. I did not ultimately find that in vitro trait assessments were good predictors of disease reduction outcomes in planta. However, my analyses did reveal differences among bacterial endophytes in their resilience to …

Isolation and Characterization of the Soybean Major Latex Homologue Msg, and Analysis of Its Pod -Specific Promoter
… without a change in expression pattern. A pathogen induction experiment on transgenic Arabidopsis plants did not show the Msg promoter to be induced after infiltration with Pseudomonas syringae. However, in soybean pods, the Msg transcript was localized by whole mount in situ hybridization …

Delivering Signal-Altering Bacterial Effector Proteins to Mammalian Cells Using Cell-Penetrating Peptide Technology
… in eukaryotes is to activate the bacterial pathogen defense response upon the detection of bacterial products in the environment. This defensive signaling results in the induction of inflammation, the transcription of antimicrobial peptides, the modulation of the cell cycle and cell …

Klonierung und Charakterisierung des PCC1-Gens ('Pathogen and circadian controlled 1')
… of a significant progress in understanding the defense signal transduction in plants, especially in Arabidopsis thaliana, there are still many open questions and new components to identify. A tool, to identify so far not characterized components of the signal-transduction-cascade is the usage of …

Sexual immune dimorphism in ecological context : the impact of estrogen on human immune function and development of bacteria killing assay.
… responses than males, providing advantages in pathogen defense but increasing the risk of autoimmune diseases. Males, in contrast, have higher susceptibility to infections, influenced by the immunosuppressive effects of testosterone. These patterns align with life history theory, which suggests …

Symbiont-Mediated Modification of Mosquitocide Toxicity in the Dengue Vector, Aedes aegypti
… to be essential in nutritional homeostasis and pathogen defense, may play a significant role in facilitating mosquitocide resistance. Here, I examined the metabolic detoxification and toxicity of two mosquitocides, propoxur and naled, and the capacity of bacterial symbionts to modify the …

Studies of E2s Related to Unconventional Ubiquitination in Arabidopsis thaliana
… one subtype had increased expression of genes in pathogen defense and showed an enhanced resistance to a plant pathogen. Therefore, the present results have provided a new understanding on the function of UBC13, identified UBC22 as a novel E2, and revealed its multiple functions in plants.

Pectin: New insights from an old polymer through pectinase-based genetic screens
… to be signal molecules involved in plant pathogen defense mechanisms. Indeed, C24 showed elevated accumulation of reactive oxygen species upon pectinase elicitation and had altered response to the pathogen Alternaria brassicicola in comparison to Col-0. Using a recombinant inbred line …

Exploring the Interface Between Macroorganisms and Microorganisms: Biochemical, Ecological, and Evolutionary Contexts
… immune response, especially coagulation and pathogen defense during attachment and metamorphosis. This work provides insight into wound healing mechanisms that facilitate coagulation of proteinaceous material and expands the knowledge of potential glue curing mechanisms in barnacles. …

Impact of arbuscular mycorrhizal fungi on crop and weed growth: potential implications for integrated weed managment
… nutrient and water uptake, stress tolerance, and pathogen defense. AMF can negatively influence the growth of some weeds, including many non-host weeds and some host weeds. Non-host weeds, which are resistant to the colonization of AMF, tend to have negative responses when interacting with AMF, …

I. Etablierung eines induzierbaren Suizidsystems zur Identifizierung von Mutanten der salizylsäureabhängigen Signaltransduktion II. Expression von tierischen Signaltransduktionskomponenten in Tabak zur Herstellung eines induzierbaren Expressionssystems
Im Rahmen der Abwehrreaktion gegen Pathogene kommt es in Pflanzen zu einem Anstieg der Salizylsäurekonzentration. Als Antwort auf dieses Signal wird die Transkription einer Reihe von Abwehrgenen über eine noch weitgehend unbekannte Signaltransduktion aktivert. Dabei unterscheidet man zwischen …
