Journal ArticleDOI
MAP kinase phosphatase1 and protein tyrosine phosphatase1 are repressors of salicylic acid synthesis and SNC1-mediated responses in Arabidopsis
Sebastian Bartels,Jeffrey C. Anderson,Marina A. González Besteiro,Alessandro Carreri,Heribert Hirt,Heribert Hirt,Antony Buchala,Jean-Pierre Métraux,Scott C. Peck,Roman Ulm +9 more
TL;DR: A major role of MKP1 and PTP1 is indicated in repressing salicylic acid biosynthesis in the autoimmune-like response caused by SNC1, which is largely the disease resistance gene homolog SUPPRESSOR of npr1-1, CONSTITUTIVE 1 that is absent in the Wassilewskija accession.
Journal ArticleDOI
Arabidopsis MAP kinase phosphatase 1 and its target MAP kinases 3 and 6 antagonistically determine UV‐B stress tolerance, independent of the UVR8 photoreceptor pathway
TL;DR: In this article, the authors show that loss of MAP kinase phosphatase 1 in the mutant MKp1 results in hypersensitivity to acute UV-B stress, but without impairing UV-b acclimation.
Journal ArticleDOI
Arabidopsis MAP Kinase Phosphatase 1 (AtMKP1) negatively regulates MPK6-mediated PAMP responses and resistance against bacteria
Jeffrey C. Anderson,Sebastian Bartels,Marina A. González Besteiro,Bationa Shahollari,Roman Ulm,Scott C. Peck +5 more
TL;DR: The identification of Arabidopsis MAP Kinase Phosphatase 1 (MKP1) as a negative regulator of diverse PAMP responses, including activation of MPK6 and MPK3, transient production of extracellular reactive oxygen species, accumulation of a subset of PAMP-regulated transcripts, and inhibition of seedling growth is reported.
Journal ArticleDOI
Emerging functions for plant MAP kinase phosphatases
TL;DR: The recent progress made by genetic studies in identifying the physiological role of plant MKPs in a multitude of cellular processes, including cytoskeleton rearrangement, stress responses and phytohormone signaling are reviewed, and the importance of negative regulators in plant MAPK signaling networks is examined.
Journal ArticleDOI
Phosphorylation and stabilization of Arabidopsis MAP kinase phosphatase 1 in response to UV-B stress
TL;DR: Stress-responsive phosphorylation and stabilization of MKP1 demonstrate the post-translational regulation of a plant MKP in vivo, adding an additional regulatory layer to MAP kinase signaling in plants.
