Abstrakt:
Mitogen-activated protein kinase kinase kinases (MAPKKK) play key roles in intra- and extracellular signaling in eukaryotes. MAPKKK MEKK1 regulates redox homeostasis in Arabidopsis. MEKK1-deficient plants are misregulated in the expression of a number of genes involved in cellular redox control and accumulate reactive oxygen species (ROS). mekk1 mutant plants exhibit a lethal phenotype when developing true leaves. In agreement with the concept that ROS negatively regulates auxin responses in plants, mekk1 mutants show reduced expression of several auxin-inducible marker genes.
