Wagner D, Przybyla D, Op den Camp R, Kim C, Landgraf F, Lee K, et al
. The genetic basis of singlet oxygen-induced stress responses of Arabidopsis thaliana. Science. 2004;306:1183-5 pubmed
..Instead, seedling lethality and growth inhibition of mature plants result from genetic programs that are activated after the release of singlet oxygen has been perceived by the plant. ..
Laloi C, Przybyla D, Apel K. A genetic approach towards elucidating the biological activity of different reactive oxygen species in Arabidopsis thaliana. J Exp Bot. 2006;57:1719-24 pubmed
..Hence, the biological activities of these two types of ROS are distinct from each other. Whether they act independently or interact is not known yet and is the topic of our current research. ..
Ochsenbein C, Przybyla D, Danon A, Landgraf F, Gobel C, Imboden A, et al
. The role of EDS1 (enhanced disease susceptibility) during singlet oxygen-mediated stress responses of Arabidopsis. Plant J. 2006;47:445-56 pubmed
..This program includes not only responses to oxidative stress, but also responses known to be activated during plant-pathogen interactions and wounding. ..
Danon A, Coll N, Apel K. Cryptochrome-1-dependent execution of programmed cell death induced by singlet oxygen in Arabidopsis thaliana. Proc Natl Acad Sci U S A. 2006;103:17036-41 pubmed
..The singlet oxygen-mediated and cryptochrome-dependent cell death response differs in several ways from PCD triggered by hydrogen peroxide/superoxide. ..
Lee K, Kim C, Landgraf F, Apel K. EXECUTER1- and EXECUTER2-dependent transfer of stress-related signals from the plastid to the nucleus of Arabidopsis thaliana. Proc Natl Acad Sci U S A. 2007;104:10270-5 pubmed
..Retrograde control of (1)O2-responsive genes requires the concerted action of both EXECUTER proteins within the plastid compartment. ..
Przybyla D, Gobel C, Imboden A, Hamberg M, Feussner I, Apel K. Enzymatic, but not non-enzymatic, 1O2-mediated peroxidation of polyunsaturated fatty acids forms part of the EXECUTER1-dependent stress response program in the flu mutant of Arabidopsis thaliana. Plant J. 2008;54:236-48 pubmed publisher
Coll N, Danon A, Meurer J, Cho W, Apel K. Characterization of soldat8, a suppressor of singlet oxygen-induced cell death in Arabidopsis seedlings. Plant Cell Physiol. 2009;50:707-18 pubmed publisher
..Suppression of (1)O2-mediated cell death in young flu/soldat8 seedlings seems to be due to a transiently enhanced acclimation at the beginning of seedling development caused by the initial disturbance of plastid homeostasis. ..
Meskauskiene R, Würsch M, Laloi C, Vidi P, Coll N, Kessler F, et al
. A mutation in the Arabidopsis mTERF-related plastid protein SOLDAT10 activates retrograde signaling and suppresses (1)O(2)-induced cell death. Plant J. 2009;60:399-410 pubmed publisher
..The results of this work reveal the unexpected complexity of what is commonly referred to as 'plastid signaling'. ..
Simková K, Moreau F, Pawlak P, Vriet C, Baruah A, Alexandre C, et al
. Integration of stress-related and reactive oxygen species-mediated signals by Topoisomerase VI in Arabidopsis thaliana. Proc Natl Acad Sci U S A. 2012;109:16360-5 pubmed publisher
..These results suggest that Topo VI acts as an integrator of multiple signals generated by reactive oxygen species formed in plants under adverse environmental conditions. ..
