The signaling modules mediated by mitogen-activated protein kinases or MAPKs participate in the transduction of different types of signals through the phosphorylation of several substrates such as enzymes, structural components, transcriptional factors and even other kinases. These modules are made up of members of three different protein families, called MAPK, MEK or MAPKK (MAP kinase kinase) and MEKK or MAPKKK (MAP kinase kinase kinase), which are activated sequentially by phosphorylation of amino acid residues located in the activation domain. By regulating the cascades of MAPKs, cells can respond to different types of stress. Furthermore, plant hormones have also been shown to influence plant response through signaling cascades mediated by MAPK. In this work we present a summary about the various hormone signaling mechanisms in Arabidopsis thaliana L., in which a signaling cascade of MAPKs participates.
