The WRKY70 Transcription Factor: A Node of Convergence for Jasmonate-Mediated and Salicylate-Mediated Signals in Plant Defense
TL;DR: It is demonstrated that the plant-specific transcription factor WRKY70 is a common component in SA- and JA-mediated signal pathways, and suggested that it acts as an activator of SA-induced genes and a repressor of JA-responsive genes, integrating signals from these mutually antagonistic pathways.
Journal ArticleDOI
WRKY70 modulates the selection of signaling pathways in plant defense
TL;DR: WRKY70 has a pivotal role in determining the balance between SA-dependent and JA-dependent defense pathways in plant response to bacterial pathogens.
Journal ArticleDOI
Overexpression of multiple dehydrin genes enhances tolerance to freezing stress in Arabidopsis.
Tuula Puhakainen,Michael W. Hess,Pirjo Mäkelä,Jan T. Svensson,Jan T. Svensson,Pekka Heino,E. Tapio Palva +6 more
TL;DR: Evidence is provided that dehydrins contribute to freezing stress tolerance in plants and it is suggested that this could be partly due to their protective effect on membranes.
Journal ArticleDOI
WRKY54 and WRKY70 co-operate as negative regulators of leaf senescence in Arabidopsis thaliana
TL;DR: The results suggest that WRKY53, WRKY54, and WRKY70 may participate in a regulatory network that integrates internal and environmental cues to modulate the onset and the progression of leaf senescence, possibly through an interaction with WRKY30.
Journal ArticleDOI
Lipopolysaccharide Heterogeneity in Salmonella typhimurium Analyzed by Sodium Dodecyl Sulfate/Polyacrylamide Gel Electrophoresis
E. Tapio Palva,P. Helena Mäkelä +1 more
TL;DR: Electrophoretic analysis of isolated cell envelopes in the presence of sodium dodecyl sulfate revealed at least 40 regularly spaced bands, which indicated major heterogeneity due to differences in chain lengths and a second heterogeneity indicated by the double character of each band.
