ZAT11, a Zinc Finger of Arabidopsis Thaliana 11, is a dual-function transcriptional regulator that positively regulates primary root growth but negatively regulates Ni 2+ tolerance. Zinc Finger of Arabidopsis Thaliana 11 (ZAT11) is a C2H2-type zinc finger protein that has been reported to function as an active transcriptional repressor. However, the(More)
Transcriptional repression of pathogen defense-related genes is essential for plant growth and development. Several proteins are known to be involved in the transcriptional regulation of plant defense responses. However, mechanisms by which expression of defense-related genes are regulated by repressor proteins are poorly characterized. Here, we describe(More)
Mitogen-activated protein kinases (MAPKs or MPKs) are one of the most important and conserved signaling molecules in plants. MPKs can directly modulate gene expression by the phosphorylation of transcription factors. However, only a few target substrates of MPKs have been isolated. Here, we identified a C2H2-type zinc finger transcription factor from(More)
Transcription factors play vital roles in stress signal transduction and gene expression modulation. The sequence analysis shows that MdCBF1 from Malus domestica Borkh. cv. Fuji contained an AP2 core domain of 56 amino acids. By comparison of deduced amino acid sequences of CBF related proteins, we deduced that MdCBF1 is a CBF transcription factor gene(More)
Mitogen-activated protein kinases (MPKs) play a crucial role in the regulation of many aspects of plant growth, development, and responses to the environment. In Arabidopsis, MPK3 and MPK6 are known to be implicated in embryonic and stomatal development as well as biotic and abiotic stress responses. However, the regulation mechanisms of plant developments(More)
Osmotic stress is induced by several environmental stresses such as drought, cold and salinity. Osmotic stress may finally leads to oxidative damage, ionic imbalance and growth inhibition in plants. Gene expression analyses indicated that ZAT10 transcription factor, a novel substrate of Arabidopsis MPKs, could be induced by environmental stresses that(More)
