Journal ArticleDOI
MYC2 differentially modulates diverse jasmonate-dependent functions in Arabidopsis.
Bruno Dombrecht,Gang Ping Xue,S. J. Sprague,John A. Kirkegaard,John Ross,James B. Reid,Gary P. Fitt,Nasser Sewelam,Nasser Sewelam,Peer M. Schenk,John M. Manners,Kemal Kazan +11 more
TL;DR: It is found that MYC2 negatively regulates Trp and Trp-derived secondary metabolism such as indole glucosinolate biosynthesis during JA signaling and positively regulates JA-mediated resistance to insect pests, and tolerance to oxidative stress, possibly via enhanced ascorbate redox cycling and flavonoid biosynthesis.
Journal ArticleDOI
Global Plant Stress Signaling: Reactive Oxygen Species at the Cross-Road.
TL;DR: A better understanding of the vital roles ROS are playing in plant signaling would help innovate new strategies to improve plant productivity under the circumstances of the increasing severity of environmental conditions and the high demand of food and energy worldwide.
Journal ArticleDOI
Spatial H2O2 signaling specificity: H2O2 from chloroplasts and peroxisomes modulates the plant transcriptome differentially.
Nasser Sewelam,Nasser Sewelam,Nils Jaspert,Katrien Van Der Kelen,Vanesa B. Tognetti,Vanesa B. Tognetti,Jessica Schmitz,Henning Frerigmann,Elia Stahl,Jürgen Zeier,Frank Van Breusegem,Veronica G. Maurino +11 more
TL;DR: It is shown that H2O2 originating in a specific organelle induces two types of responses: one that integrates signals independently from the subcellular site of H1N1 production and another that is dependent on the H2 O2 production site.
Journal ArticleDOI
Heterotrimeric G proteins-mediated resistance to necrotrophic pathogens includes mechanisms independent of salicylic acid-, jasmonic acid/ethylene- and abscisic acid-mediated defense signaling.
Yuri Trusov,Nasser Sewelam,James E. Rookes,Matt Kunkel,Ekaterina Nowak,Peer M. Schenk,José Ramón Botella +6 more
TL;DR: Analysis of the double mutants showed that the Gβ-mediated resistance to F. oxysporum and Alternaria brassicicola was mostly independent of all of the previously mentioned pathways, however, the progressive decay of agb1-2 mutants was compensated by coi1-21 and jin1-9 mutations, suggesting that at this stage of F.OxysporUM infection Gβ acts upstream of COI1 and ATMYC2 in JA signaling.
Journal ArticleDOI
Ethylene Response Factor 6 Is a Regulator of Reactive Oxygen Species Signaling in Arabidopsis
Nasser Sewelam,Kemal Kazan,Skye R. Thomas-Hall,Brendan N. Kidd,John M. Manners,Peer M. Schenk +5 more
TL;DR: The results indicate that ERF6 plays an important role as a positive antioxidant regulator during plant growth and in response to biotic and abiotic stresses.
