Journal ArticleDOI
The redox-sensitive transcription factor Rap2.4a controls nuclear expression of 2-Cys peroxiredoxin A and other chloroplast antioxidant enzymes
Jehad Shaikhali,Isabelle Heiber,Thorsten Seidel,Elke Ströher,Heiko Hiltscher,Stefan Birkmann,Karl-Josef Dietz,Margarete Baier +7 more
TL;DR: The redox sensitivity of Rap2.4a establishes an efficient switch mechanism for redox control of nuclear gene activity of chloroplast antioxidants, in which Rap 2.4 is a redox-sensor and a transducer of redox information.
Journal ArticleDOI
Redox-mediated Mechanisms Regulate DNA Binding Activity of the G-group of Basic Region Leucine Zipper (bZIP) Transcription Factors in Arabidopsis
Jehad Shaikhali,Louise Norén,Juan de Dios Barajas-López,Vaibhav Srivastava,Janine König,Uwe Sauer,Gunnar Wingsle,Karl-Josef Dietz,Åsa Strand +8 more
TL;DR: The results suggest that environmentally induced changes in the redox state regulate the activity of members of the G-group of bZIP transcription factors.
Journal ArticleDOI
Interplay between Heat Shock Protein 90 and HY5 controls PhANG expression in response to the GUN5 plastid signal.
TL;DR: It is revealed that HSP90 proteins respond to the tetrapyrrole-mediated plastid signal to control expression of photosynthesis-associated nuclear genes (PhANG) during the response to oxidative stress and that Mg-ProtoIX, cytosolic H SP90, and HY5 are all part of the same signaling pathway.
Journal ArticleDOI
The CRYPTOCHROME1-Dependent Response to Excess Light Is Mediated through the Transcriptional Activators ZINC FINGER PROTEIN EXPRESSED IN INFLORESCENCE MERISTEM LIKE1 and ZML2 in Arabidopsis
Jehad Shaikhali,Juan de Dios Barajas-López,Krisztina Ötvös,Krisztina Ötvös,Dmitry Kremnev,Ana Sánchez Garcia,Vaibhav Srivastava,Gunnar Wingsle,László Bakó,Åsa Strand +9 more
TL;DR: This work identifies ZML2 and its homolog ZML1 as key regulators of gene expression in the cry1-dependent response to excess light and GATA transcription factors as two essential components of thecry1-mediated photoprotective response.
Journal ArticleDOI
The radical induced cell death protein 1 (RCD1) supports transcriptional activation of genes for chloroplast antioxidant enzymes.
Heiko Hiltscher,Radoslaw Rudnik,Jehad Shaikhali,Jehad Shaikhali,Isabelle Heiber,Marina Mellenthin,Iuri Meirelles Duarte,Günter Schuster,Uwe Kahmann,Margarete Baier,Margarete Baier,Margarete Baier +11 more
TL;DR: It is concluded that RCD1 protects plant cells from running into reactive oxygen species (ROS)-triggered programs, such as cell death and activation of pathogen-responsive genes (PR genes) and extra-plastidic antioxidant enzymes, by supporting the induction of the chloroplast antioxidant system.
