The MAP kinase kinase MKK2 affects disease resistance in Arabidopsis.
The Arabidopsis mitogen-activated protein kinase (MAPK) kinase 2 (MKK2) was shown to mediate cold and salt stress responses through activation of the two MAP kinases MPK4 and MPK6. Transcriptome analysis of plants expressing constitutively active MKK2 (MKK2-EE plants) showed altered expression of genes induced by abiotic stresses but also a significant number of genes involved in defense respon...
متن کاملMAP Kinase Cascades in Arabidopsis Innate Immunity
Plant mitogen-activated protein kinase (MAPK) cascades generally transduce extracellular stimuli into cellular responses. These stimuli include the perception of pathogen-associated molecular patterns (PAMPs) by host transmembrane pattern recognition receptors which trigger MAPK-dependent innate immune responses. In the model Arabidopsis, molecular genetic evidence implicates a number of MAPK c...
متن کاملPhosphorylation of Xenopus mitogen-activated protein (MAP) kinase kinase by MAP kinase kinase kinase and MAP kinase.
Xenopus 45-kDa mitogen-activated protein (MAP) kinase kinase (MAPKK) is a serine/threonine/tyrosine kinase, which activates MAP kinase (MAPK) by phosphorylating its threonine and tyrosine residues. MAPKK is active only when its threonine and/or serine residues are phosphorylated. We have identified from Xenopus eggs two protein kinases responsible for phosphorylation of MAPKK. The two kinases a...
متن کاملThe Arabidopsis MAP kinase kinase MKK1 participates in defence responses to the bacterial elicitor flagellin.
Plants sense pathogens through both pathogen-associated molecular patterns and recognition of race-specific virulence factors, which induce basal defence or an accelerated defence (often manifest in the form of local cell death), respectively. A mitogen-activated protein kinase (MAPK) module in Arabidopsis was previously proposed to signal from perception of the bacterial elicitor flagellin to ...
متن کاملInteraction of MAP kinase with MAP kinase kinase: its possible role in the control of nucleocytoplasmic transport of MAP kinase.
The mitogen-activated protein kinase (MAPK) cascade consisting of MAPK and its direct activator, MAPK kinase (MAPKK), is essential for signaling of various extracellular stimuli to the nucleus. Upon stimulation, MAPK is translocated to the nucleus, whereas MAPKK stays in the cytoplasm. It has been shown recently that the cytoplasmic localization of MAPKK is determined by its nuclear export sign...
