Towards the identification and functional characterization of molecular components involved in PEN2-mediated entry control of non-adapted powdery mildews in Arabidopsis
(2021-08-05)The Arabidopsis thaliana cytochrome P450 monooxygenase CYP81F2 and the myrosinase PENE-TRATION2 (PEN2) are important components for broad-spectrum pre-invasion defense against filamentous plant pathogens, including non-adapted ... -
Identification and Characterization of Novel Genes involved in Quinone Synthesis in the Odoriferous Defensive Stink Glands of the Red Flour Beetle, Tribolium castaneum
(2021-05-26)Defense strategies are common in insects including Coleoptera, the largest animal taxon containing various types of beetles. Stink gland secretion of beetles is playing an important role in their defense against detrimental ... -
Towards the identification and functional characterization of Verticillium effectors involved in xylem hyperplasia formation in Arabidopsis
(2020-05-26)Isolates of the vascular plant pathogen Verticillium spp. can be categorized according to the disease phenotypes they induce on Arabidopsis thaliana Col-0 plants (Thole 2016). While Arabidopsis plants show no obvious disease ... -
Functional analysis of the Arabidopsis thaliana glutaredoxin ROXY9
(2019-05-24)Glutaredoxins are nearly ubiquitious small enzymes which protect the thiol groups of cellular proteins from oxidative stress, contribute to iron-sulfur cluster biogenesis or regulate protein activities via redox modification. ... -
Sphingolipids in <i>Physcomitrella patens</i>
(2019-05-10)The model organism Physcomitrella patens is a bryophyte in the group of non-vascular plants. Evolutionary, bryophytes evolved shortly after the event when plants developed the ability to grow on land. P. patens can therefore ... -
Verticillium dahliae transcription factors Som1 and Vta3 control microsclerotia formation and sequential steps of plant root penetration and colonisation to induce disease
(2018-10-12)Verticillium dahliae belongs to the soil-borne ascomycete fungi. It causes wilt diseases and early senescence in more than 200 plant species including economically important crops. It can exist in the soil without a host ... -
Molecular analysis of importin-α-mediated nucleocytoplasmic signaling in plant innate immunity
(2015-04-30)IMPORTIN-αs are a family of nuclear transport receptors that mediate the translocation of nuclear localization signal (NLS)-containing cargo proteins from the cytoplasm into the nucleus through nuclear pores. The IMPORTIN-α3, ... -
Die Rolle von Phosphoinositiden bei der Auxinsignalleitung von Arabidopsis thaliana
(2013-05-28)The influence of the phosphoinositide network on auxin-signaling in Arabidopsis thaliana The phytohormone auxin (IAA) is a key regulator of growth and organ formation as well as a signal for tropical responses in plants, ... -
Structure and function of A.nidulans PSI factor producing oxygenase A
(2013-04-25)Phytopathogenic fungi are not only of economic importance for the yield depression they cause, but can also be considered as severe threat for the health of the consumer ingesting molded crops and fruits. This health threat ... -
Signals and metabolic consequences during the interaction of Brassicaceae and <i>Verticillium longisporum</i>
(2013-01-14)The soil-borne, hemibiotrophic pathogen Verticillium longisporum is a severe threat for oilseed rape (Brassica napus) cultivation. In order to develop effective, defensive treatments for infected plants a thorough understanding ... -
Phenylpropanoids and long chain fatty acid derivatives in the interaction of <i>Arabidopsis thaliana</i> and <i>Verticillium longisporum</i>
(2012-10-02)Verticillium longisporum is a soil borne pathogen which infects plants of the Brassicaceae family. The fungus enters through the roots and spreads within the plant through the xylem. Using the model plant Arabidopsis ... -
Impact of specific long chain acyl CoA synthetases on plant development
(2012-06-18)Fatty acids are essential components of cellular life. However, in their natural form they cannot enter metabolism but in fact they need enzymatic activation by coenzyme A to become metabolically accessible. One enzyme ... -
Regulation of Kinesin-3 activity by active zone protein SYD-2
(2011-12-12)This work focusses on characterizing the effect of SYD-2/kinesin interaction on the motility and mechanochemical properties of UNC-104 motor. The motility properties of molecular motors can ... -
The production of VLCPUFAs in plants
(2011-03-17)Very long-chain polyunsaturated fatty acids (VLCPUFAs) like eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) are health-beneficial components in the human diet. However, due to ... -
