Journal ArticleDOI
Arabidopsis CBF1 overexpression induces COR genes and enhances freezing tolerance.
Kirsten Jaglo-Ottosen,Sarah J. Gilmour,Daniel Zarka,Oliver Schabenberger,Michael F. Thomashow +4 more
TL;DR: Increased expression of Arabidopsis CBF1, a transcriptional activator that binds to the CRT/DRE sequence, induced COR gene expression and increased the freezing tolerance of nonacclimatedArabidopsis plants.
Journal ArticleDOI
Low temperature regulation of the Arabidopsis CBF family of AP2 transcriptional activators as an early step in cold-induced COR gene expression
Sarah J. Gilmour,Daniel Zarka,Eric J. Stockinger,Maite P. Salazar,Jaimie M. Houghton,Michael F. Thomashow +5 more
TL;DR: It is proposed that cold-induced expression of CRT/DRE-containing COR genes involves a low temperature-stimulated signalling cascade in which CBF gene induction is an early event and theCBF gene family is not subject to autoregulation.
Journal ArticleDOI
Roles of the CBF2 and ZAT12 transcription factors in configuring the low temperature transcriptome of Arabidopsis.
TL;DR: Constitutive expression of ZAT 12 in Arabidopsis caused a small, but reproducible, increase in freezing tolerance, indicating a role for the ZAT12 regulon in cold acclimation.
Journal ArticleDOI
Cold induction of Arabidopsis CBF genes involves multiple ICE (inducer of CBF expression) promoter elements and a cold-regulatory circuit that is desensitized by low temperature.
TL;DR: Results presented here indicate that the cold-sensing mechanism does not require a cold shock to bring about the accumulation of CBF transcripts, but instead, absolute temperature is monitored with a greater degree of input, resulting in a greater output, i.e. higher levels ofCBF transcripts.
Journal ArticleDOI
Abscisic acid induces CBF gene transcription and subsequent induction of cold-regulated genes via the CRT promoter element.
TL;DR: It is shown that ABA is also capable of activating the C-repeat element (CRT; dehydration-responsive) promoter element via CBF (DREB1) transcription factors, and data indicate that activation of the CRT may also occur via a novel ABA-inducible signaling pathway using the normally cold-Inducible CBFs.
