VIP1 is very important/interesting protein 1 regulating touch responses of Arabidopsis
VIP1 (VIRE2-INTERACTING PROTEIN 1) is a bZIP transcription factor in Arabidopsis thaliana. VIP1 and its close homologs (i.e., Arabidopsis group I bZIP proteins) are present in the cytoplasm under steady conditions, but are transiently localized to the nucleus when cells are exposed to hypo-osmotic conditions, which mimic mechanical stimuli such as touch. Recently we have reported that overexpre...
متن کاملThe bZIP Protein VIP1 Is Involved in Touch Responses in Arabidopsis Roots.
VIP1 is a bZIP transcription factor in Arabidopsis (Arabidopsis thaliana). VIP1 transiently accumulates in the nucleus when cells are exposed to hypoosmotic conditions, but its physiological relevance is unclear. This is possibly because Arabidopsis has approximately 10 close homologs of VIP1 and they function redundantly. To examine their physiological roles, transgenic plants overexpressing a...
متن کاملAnalysis of Functions of VIP1 and Its Close Homologs in Osmosensory Responses of Arabidopsis thaliana
VIP1 is a bZIP protein in Arabidopsis thaliana. VIP1 accumulates in the nucleus under hypo-osmotic conditions and interacts with the promoters of hypo-osmolarity-responsive genes, CYP707A1 and CYP707A3 (CYP707A1/3), but neither overexpression of VIP1 nor truncation of its DNA-binding region affects the expression of CYP707A3 in vivo, raising the possibility that VIP and other proteins are funct...
متن کاملCharacterization of VIP1 activity as a transcriptional regulator in vitro and in planta
VIP1 (VirE2 interacting protein 1), initially discovered as a host protein involved in Agrobacterium-plant cell DNA transfer, is a transcription factor of the basic leucine-zipper (bZIP) domain family that regulates several defence-related genes in Arabidopsis. We have developed assays to assess VIP1 binding to its DNA target in vitro and transcriptional activation efficiency in planta. Several...
متن کاملVIP1 response elements mediate mitogen-activated protein kinase 3-induced stress gene expression.
The plant pathogen Agrobacterium tumefaciens transforms plant cells by delivering its T-DNA into the plant cell nucleus where it integrates into the plant genome and causes tumor formation. A key role of VirE2-interacting protein 1 (VIP1) in the nuclear import of T-DNA during Agrobacterium-mediated plant transformation has been unravelled and VIP1 was shown to undergo nuclear localization upon ...
