Many plants increase in freezing tolerance upon exposure to low nonfreezing temperatures, a phenomenon known as cold acclimation. In this review, recent advances in determining the nature and function of genes with roles in freezing tolerance and the mechanisms involved in low temperature gene regulation and signal transduction are described. One of the important conclusions to emerge from these studies is that cold acclimation includes the expression of certain cold-induced genes that function…

Cold resistance in plants: A mystery unresolved

TLDR
Genetic analysis has revealed important roles for cellular metabolic signals, and for RNA splicing, export and secondary structure unwinding, in regulating cold-responsive gene expression and chilling and freezing tolerance, which further the understanding of the basic mechanisms that plants have evolved to survive freezing temperatures.

Cold comfort farm: the acclimation of plants to freezing temperatures.

TLDR
It is recognized that several interacting signal pathways are activated to bring about cold acclimation and ensure the winter survival of plants.

Cold Acclimation and Freezing Tolerance in Plants

TLDR
B Brachypodium distachyon is a potential model for the study of cold acclimation and the regulation of cold stress response and chromatin dynamics have been identified in plants thus far.

Review. Regulatory mechanisms involved in cold acclimation response

TLDR
Recent reports have shown that RNA processing and export, as well as post-translational modifications, including ubiquitylation and SUMOylation, also play important roles in regulating cold acclimation, and histone modifications seem to be relevant in this regulation.

Arabidopsis transcription factors regulating cold acclimation

TLDR
What is known about the CBF cold-response pathway is reviewed, including several recent developments, and emerging evidence in support of several additional transcription factors having roles in freezing tolerance pathways is discussed.

TLDR
Recent advances in cold stress signaling and tolerance are highlighted and it is demonstrated that post-transcriptional and post- translational regulations play a role in the regulation of cold signaling.

Biological Mechanisms of Low Temperature Stress Responsse: Cold Acclimation and Development of Freezing Tolerance in Plants

TLDR
Understanding the molecular basis of plant cold acclimation response already provides several strategies to improve freezing tolerance in plants and modulation of the key components of low temperature responsepathways (regulon engineering) provides a way for improving plant stress tolerance.

Regulatory network of gene expression during the development of frost tolerance in plants

TLDR
Analysis of genes expression in response to cold acclimation showed that photosynthetic genes down-regulated as medium to long term cold-responsive genes, however the genes involved in the synthesis of osmoprotectants - organic compounds, enzymatic antioxidant, anti-pathogenic polypeptides, cytoskeletal proteins and others significantly up-regulate during overwintering.

TLDR
The characterization of esk1 mutants and results from other mutants suggest that distinct signaling pathways activate different aspects of cold acclimation and that activation of one pathway can result in considerable freezing tolerance without activation of other pathways.

The molecular biology of plant acclimation to low temperature

TLDR
A number of plant genes, which are up-regulated at steady-state mRNA levels by an acclimation treatment, have been isolated from both monocotyledon and dicotylingon species and the precise function of the proteins encoded by these genes is unknown.

Molecular Cloning and Expression of cor (Cold-Regulated) Genes in Arabidopsis thaliana.

TLDR
The isolation of cDNA clones of four cold-regulated (cor) genes from Arabidopsis thaliana are reported and their expression in response to low temperature, abscisic acid (ABA), water stress, and heat shock is examined.

Regulation of Arabidopsis thaliana L. (Heyn) cor78 in Response to Low Temperature

TLDR
The results of gene-fusion experiments confirm the finding that the 5[prime] region of cor78 has cis-acting regulatory elements that can impart cold-regulated gene expression and histochemical staining experiments indicated that this cold-regulatory element(s) was active at low temperature throughout much of the plant.

Constitutive expression of the cold-regulated Arabidopsis thaliana COR15a gene affects both chloroplast and protoplast freezing tolerance.

TLDR
Constutive expression of COR15a, a cold-regulated gene of Arabidopsis thaliana that encodes a chloroplast-targeted polypeptide, enhances the in vivo freezing tolerance of chloroplasts in nonacclimated plants by almost 2 degrees C, nearly one-third of the increase that occurs upon cold acclimation of wild-type plants.

The wheat wcs120 gene family. A useful model to understand the molecular genetics of freezing tolerance in cereals

TLDR
These analyses revealed a regulatory control of the vernalization process over low temperature gene expression in winter cereals, and accumulation of WCS protein is directly correlated with the development of freezing tolerance.

Arabidopsis CBF1 overexpression induces COR genes and enhances freezing tolerance.

TLDR
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.

Antifreeze protein accumulation in freezing-tolerant cereals

TLDR
The results showed that significant levels of antifreeze activity were present only in the apoplast of freezing-tolerant monocotyledons after cold acclimation at 5/2°C, indicating that the accumulation of antIFreeze proteins is a specific response that may be important in the freezing tolerance of some plants, rather than a general response of all plants to low temperature stress.
