the AtMKK2-AtMPK10 MAPK module regulates leaf venation complexity by altering polar auxin transport efficiency
Title: Timing is everything: highly specific and transient expression of a MAP kinase determines auxin-induced leaf venation patterns in Arabidopsis.

Treatment of Arabidopsis with a membrane rigidifier, DMSO, causes MPK4 activation concomitantly with MEKK1 and MKK2 phosphorylation.
Title: Membrane rigidification functions upstream of the MEKK1-MKK2-MPK4 cascade during cold acclimation in Arabidopsis thaliana.

Ca(2+) signaling occurred upstream of the MEKK1-MKK2 pathway. MEKK1 was phosphorylated by calcium/calmodulin-regulated receptor-like kinase (CRLK1), which suggested that CRLK1 is one of candidates located upstream of MEKK1.
Title: Phosphorylation of Arabidopsis thaliana MEKK1 via Ca(2+) signaling as a part of the cold stress response.

Data indicate that MEKK2 is required for the mekk1, mkk1 mkk2, and mpk4 autoimmune phenotypes.
Title: Deletion of a tandem gene family in Arabidopsis: increased MEKK2 abundance triggers autoimmunity when the MEKK1-MKK1/2-MPK4 signaling cascade is disrupted.

Data suggest that the MEKK1-MKK1/MKK2-MPK4 kinase cascade negatively regulates MEKK2 and activation of MEKK2 triggers SUMM2-mediated immune responses.
Title: The MEKK1-MKK1/MKK2-MPK4 kinase cascade negatively regulates immunity mediated by a mitogen-activated protein kinase kinase kinase in Arabidopsis.
