Reactive oxygen species signaling in plants.
Pitzschke A, Forzani C, Hirt H. Pitzschke A, et al. Antioxid Redox Signal. 2006 Sep-Oct;8(9-10):1757-64. doi: 10.1089/ars.2006.8.1757. Antioxid Redox Signal. 2006. PMID: 16987029 Review.
A common property of all ROS types is that they can cause oxidative damage to proteins, DNA, and lipids. This toxicity of ROS explains the evolution of complex arrays of nonenzymatic and enzymatic detoxification mechanisms in plants. ...

Mitogen-activated protein kinase-regulated AZI1 - an attractive candidate for genetic engineering.
Pitzschke A, Datta S, Persak H. Pitzschke A, et al. Plant Signal Behav. 2014;9(2):e27764. doi: 10.4161/psb.27764. Epub 2014 Feb 10. Plant Signal Behav. 2014. PMID: 24518841 Free PMC article.
In a recent study, we reported AZI1, a member of the lipid transfer protein family, to play a role in MPK3-mediated responses to salt stress in Arabidopsis thaliana. ...A model of multi-level control of AZI1 by MPK3 is proposed, and strategies toward o …

VIP1 response elements mediate mitogen-activated protein kinase 3-induced stress gene expression.
Pitzschke A, Djamei A, Teige M, Hirt H. Pitzschke A, et al. Proc Natl Acad Sci U S A. 2009 Oct 27;106(43):18414-9. doi: 10.1073/pnas.0905599106. Epub 2009 Oct 9. Proc Natl Acad Sci U S A. 2009. PMID: 19820165 Free PMC article.
Here, we provide evidence that VIP1 encodes a functional bZIP transcription factor that stimulates stress-dependent gene expression by binding to VIP1 response elements (VREs), a DNA hexamer motif. ...Trxh8 and MYB44 promoters are activated by VIP1 in a VRE-d …

Djamei A, Pitzschke A, Nakagami H, Rajh I, Hirt H. Djamei A, et al. Science. 2007 Oct 19;318(5849):453-6. doi: 10.1126/science.1148110. Science. 2007. PMID: 17947581
Nuclear import of transfer DNA (T-DNA) is a central event in Agrobacterium transformation of plant cells and is thought to occur by the hijacking of certain host cell proteins. ...Here we show that VIP1 is a transcription factor that is a direct target of the …
