Effects of cold stress on reproductive biology and epigenetic profiles of the alpine plant Ranunculus kuepferi (Ranunculaceae)
(2022-01-17)Alpine habitats are shaped by harsh abiotic conditions and cold climates. Plant life in such habitats is challenging, as environmental influence can alter the conditions for development and reproduction. More specifically, ... -
Analysis of the JA-Ile-independent function of COI1 in Arabidopsis thaliana upon infection with Verticillium longisporum
(2021-09-24)CORONATINE INSENSITIVE 1 (COI1) perceives the plant hormone jasmonoyl-isoleucine (JA-Ile) together with proteins of the JASMONATE ZIM-domain (JAZ) family. JA-Ile induces signalling cascades in defence and developmental ... -
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 ... -
Reproductive strategies of alpine apomictic plants under different ecological conditions
(2019-06-06)The origin of apomixis in natural populations is still not well understood. Apomictic plants tend to expand their distribution range more to higher latitudes and altitudes compared to their sexual progenitors, a phenomenon ... -
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. ... -
Metabolic fate of jasmonates
(2019-01-21)Jasmonoyl-isoleucine (JA-Ile) is a phytohormone that orchestrates responses to wounding, feeding insects or necrotrophic pathogens in plants. JA-Ile-metabolism has been studied intensively (Wasternack, 2015) and most of ... -
Plant-specific glutaredoxin ROXY9 regulates hyponastic growth by inhibiting TGA1 function
(2017-04-04)In the rosette plant Arabidopsis thaliana, different environmental cues trigger upward (hyponastic) leaf movement which is evolutionary beneficial when it comes to avoid shading by neighboring plants. Hyponasty results ... -
Analysis of CERK1 ectodomain shedding and the role of XLG2 in cerk1-4 cell death execution
(2016-05-20)Conserved microbial signatures are perceived via plasma membrane localized pattern recognition receptors (PRRs). In Arabidopsis, perception of the fungal cell wall component chitin requires the LysM receptor-like kinase ... -
Analysis of the transcriptional repressor function of Arabidopsis glutaredoxin ROXY19
(2016-02-25)Glutaredoxins (GRXs) are small ubiquitous proteins that are characterized by a thioredoxin (TRX) fold and a glutathione (GSH) reducible active site, which is a CPYC motif in class I GRXs and a CGFS motif in class II GRXs. ... -
The functional characterization of a root knot nematode effector Mi131 and an investigation of the role of jasmonic acid during the Arabidopsis-root knot nematode interaction
(2015-12-15)Root knot nematodes (Meloidogyne spp.) are devastating pests to agriculture worldwide. The best control measure for these small, microscopic roundworms is to fumigate the field with nematicides prior to planting. However ... -
Nebenwege des zentralen Kohlenstoffmetabolismus von Bacillus subtilis: Regulation der Methylglyoxalsynthase und der Zitratsynthase CitA
(2015-09-22)The phosphoenolpyruvate phosphotransferase system plays a crucial role in carbon metabolism of Bacillus subtilis. Besides uptake of different sugars the components of the PTS exert regulatory functions. This also accounts ... -
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, ... -
Characterization of Clade I TGA Transcription Factors in Arabidopsis thaliana with Respect to Biotic Stress
(2015-04-14)Activation of the plant immune system after pathogen attack involves massive transcriptional reprogramming. In Arabidopsis thaliana, clade I TGA transcription factors (TFs) TGA1 and TGA4 have been shown to contribute to ... -
Transkriptionelle Regulation des pflanzlichen Detoxifikationsprogramms durch das GRAS-Protein SCL14
(2015-03-31)In plants, the contact with toxic substances activates a group of genes, which are involved in the detoxification of these substances. A subgroup of these genes is regulated by the transcriptional coactivator Scarecrow-like ... -
Identification of the role of Arabidopsis ATAF-type NAC transcription factors in plant stress and development
(2014-05-14)In higher plants, xenobiotic chemicals induce transcriptional activation of genes involved in their detoxification. A generally accepted concept explaining gene regulatory networks is that, activation of pre-existing ... -
The role of defense signaling pathways in the interaction of Arabidopsis thaliana and Vertcillium longisporum
(2013-08-26)Verticillium longisporum is a soil-borne fungal pathogen causing vascular disease predominantly in oilseed rape. The pathogen enters its host through the roots and maintains a parasitic life stage in the xylem before ... -

(2012-06-27)The atypical myrosinase PEN2 is a molecular component of nonhost resistance in Arabidopsis thaliana. Using a functional GFP-fusion protein revealed the localisation of PEN2 in the periphery of mobile membrane compartments, ... -
Arabidopsis basic leucine Zipper transcription factors function as quantitative modulators of auxin mediated transcription
(2012-04-10)The essential plant growth hormone auxin orchestrates a wide range of developmental and environmental processes in the course of plant life. In general, these responses are predominately implemented by the encoded activity ... -
Arabidopsis thaliana class II TGA transcription factors provide a molecular link between salicylic acid and ethylene defense signalling
(2011-11-15)Since plants are exposed to a multitude of different attackers, a complex innate immune system has evolved to protect them from devastating diseases. Depending on the type of pathogen or ... -
