Mutational Evidence for the Critical Role of CBF Transcription Factors in Cold Acclimation in Arabidopsis.
The three tandemly arranged CBF genes, CBF1, CBF2, and CBF3, are involved in cold acclimation. Due to the lack of stable loss-of-function Arabidopsis (Arabidopsis thaliana) mutants deficient in all three CBF genes, it is still unclear whether the CBF genes are essential for freezing tolerance and whether they may have other functions besides cold acclimation. In this study, we used the CRISPR/C...
متن کاملCAMTA proteins: a direct link between calcium signals and cold acclimation?
Plants in temperate regions have a remarkable capacity for cold acclimation; that is, they acquire enhanced tolerance to freezing after exposure to low nonfreezing temperatures. CBF transcription factors play a critical role in this process. In Arabidopsis, CBF genes are rapidly induced following exposure to cold temperature, and the CBF factors in turn induce the expression of ;100 other genes...
متن کاملInvolvement of CBF transcription factors in winter hardiness in birch.
Cold acclimation of plants involves extensive reprogramming of gene expression. In Arabidopsis (Arabidopsis thaliana), three cold-inducible transcriptional activators designated CBF1 to -3/DREB1a to -c have been shown to play an important regulatory role in this acclimation process. Similarly to Arabidopsis, boreal zone trees can increase their freezing tolerance (FT) in response to low tempera...
متن کاملArabidopsis transcriptome profiling indicates that multiple regulatory pathways are activated during cold acclimation in addition to the CBF cold response pathway.
Many plants, including Arabidopsis, increase in freezing tolerance in response to low, nonfreezing temperatures, a phenomenon known as cold acclimation. Previous studies established that cold acclimation involves rapid expression of the CBF transcriptional activators (also known as DREB1 proteins) in response to low temperature followed by induction of the CBF regulon (CBF-targeted genes), whic...
متن کاملCold responsive gene transcription becomes more complex.
CBF transcription factors, which play important roles in cold acclimation, regulate the expression of approximately 170 cold-responsive genes, termed the CBF regulon. Recent work by Park et al. showed that CBF regulon genes and other cold-responsive genes are regulated by a complex network that involves many early cold-induced transcription factors.
