2-Cysteine Peroxiredoxins and Thylakoid Ascorbate Peroxidase create a water-water cycle that is essential to protect the photosynthetic apparatus under high light stress conditions
Awad, Jasmin; Stotz, Henrik; Fekete, Agnes; Krischke, Markus; Engert, Cornelia; Havaux, Michel; Berger, Susanne; Mueller, Martin J. (2015-04-01)Different peroxidases, including 2-cysteine (2-Cys) peroxiredoxins (PRXs) and thylakoid ascorbate peroxidase (tAPX), have been proposed to be involved in the water-water cycle (WWC) and hydrogen peroxide (H2O2)-mediated ... -

Defense against Sclerotinia sclerotiorum in Arabidopsis is dependent on jasmonic acid, salicylic acid, and ethylene signaling
Guo, X.; Stotz, Henrik (2007-11)Genotypic differences in susceptibility of Arabidopsis thaliana to Sclerotinia sclerotiorum have not been reported due to the extreme susceptibility of this cruciferous plant. To overcome this limitation, we have established ... -
A defensin from tomato with dual function in defense and development
Stotz, Henrik; Spence, Brandi; Wang, Yueju (2009)Defensins are antimicrobial peptides that are part of the innate immune system, contributing to the first line of defense against invading pathogens. Defensins and defensin-like peptides are functionally diverse, disrupting ... -
Determination of the pathogen population structure of Pyrenopeziza brassicae, causal agent of light leaf spot on brassicas
Kloppel, Coretta; Stotz, Henrik; Fitt, Bruce D.L. (2014)Light leaf spot, caused by the fungal pathogen Pyrenopeziza brassicae, is currently the major disease problem in oilseed rape production in the UK. Furthermore, P. brassicae can also be found on vegetable brassicas such ... -

Effector-triggered defence against apoplastic fungal pathogens
Stotz, Henrik; Mitrousia, Georgia; de Wit, Pierre; Fitt, Bruce D.L. (2014-08-01)R gene-mediated host resistance against apoplastic fungal pathogens is not adequately explained by the terms pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) or effector-triggered immunity (ETI). ... -
Effects of a penthiopyrad and picoxystrobin fungicide mixtureon phoma stem canker (Leptosphaeria spp.) on UK winteroilseed rape
Sewell, Thomas; Moloney, Steven; Ashworth, Mike; Ritchie, Faye; Mashanova, Alla; Huang, Yongju; Stotz, Henrik; Fitt, Bruce (2016-07-01)In the UK, fungicides are often used to controlphoma stem canker on winter oilseed rape.
