“…These abiotic stresses not only limit the geographical distribution of plants but also reduce the global productivity and quality of important agricultural crops. Although plant temperature changes with the ambient temperature, most temperate plants can acquire tolerance to freezing temperatures by a prior exposure to low nonfreezing temperatures, a process termed cold acclimation (Guy, 1990;Thomashow, 1999;Ruelland et al, 2009). Freezing tolerance is essential for temperate crops like winter wheat (Triticum aestivum) and canola (Brassica napus), but tropical and subtropical plants are incapable of cold acclimation.…”

A DEAD Box RNA Helicase Is Critical for Pre-mRNA Splicing, Cold-Responsive Gene Regulation, and Cold Tolerance inArabidopsis

Cold stress resulting from chilling and freezing temperatures substantially reduces crop production worldwide. To identify genes critical for cold tolerance in plants, we screened Arabidopsis thaliana mutants for deregulated expression of a firefly luciferase reporter gene under the control of the C-REPEAT BINDING FACTOR2 (CBF2) promoter (CBF2:LUC). A regulator of CBF gene expression1 (rcf1-1) mutant that is hypersensitive to cold stress was chosen for in-depth characterization. RCF1 encodes a cold-inducible DEAD (Asp-Glu-Ala-Asp) box RNA helicase. Unlike a previously reported DEAD box RNA helicase (LOW EXPRESSION OF OSMOTICALLY RESPONSIVE GENES4 [LOS4]) that regulates mRNA export, RCF1 does not play a role in mRNA export. Instead, RCF1 functions to maintain proper splicing of pre-mRNAs; many cold-responsive genes are misspliced in rcf1-1 mutant plants under cold stress. Functional characterization of four genes (PSEUDO-RESPONSE, and SPFH/PHB DOMAIN-CONTAINING MEMBRANE-ASSOCIATED PROTEIN [SPFH]) that are misspliced in rcf1-1 revealed that these genes are cold-inducible positive (CIR1 and SPFH) and negative (PRR5 and SK12) regulators of cold-responsive genes and cold tolerance. Together, our results suggest that the cold-inducible RNA helicase RCF1 is essential for pre-mRNA splicing and is important for cold-responsive gene regulation and cold tolerance in plants.

“…Physiological, biochemical, and molecular changes that occur in plants in response to low temperature have been extensively reviewed Chinnusamy et al, 2007;Zhu et al, 2007;Guy et al, 2008;Ruelland et al, 2009). One important cold signaling pathway, controlled by C-repeat/droughtresponsive element binding factors (CBFs) has been shown to enhance freezing tolerance in Arabidopsis (Arabidopsis thaliana; Jaglo-Ottosen et al, 1998;Gilmour et al, 2000).…”

To gain insight into the molecular basis contributing to overwintering hardiness, a comprehensive proteomic analysis comparing crowns of octoploid strawberry (Fragaria 3 ananassa) cultivars that differ in freezing tolerance was conducted. Four cultivars were examined for freeze tolerance and the most cold-tolerant cultivar ('Jonsok') and least-tolerant cultivar ('Frida') were compared with a goal to reveal how freezing tolerance is achieved in this distinctive overwintering structure and to identify potential cold-tolerance-associated biomarkers. Supported by univariate and multivariate analysis, a total of 63 spots from twodimensional electrophoresis analysis and 135 proteins from label-free quantitative proteomics were identified as significantly differentially expressed in crown tissue from the two strawberry cultivars exposed to 0-, 2-, and 42-d cold treatment. Proteins identified as cold-tolerance-associated included molecular chaperones, antioxidants/detoxifying enzymes, metabolic enzymes, pathogenesis-related proteins, and flavonoid pathway proteins. A number of proteins were newly identified as associated with cold tolerance. Distinctive mechanisms for cold tolerance were characterized for two cultivars. In particular, the 'Frida' cold response emphasized proteins specific to flavonoid biosynthesis, while the more freezing-tolerant 'Jonsok' had a more comprehensive suite of known stress-responsive proteins including those involved in antioxidation, detoxification, and disease resistance. The molecular basis for 'Jonsok'-enhanced cold tolerance can be explained by the constitutive level of a number of proteins that provide a physiological stress-tolerant poise. Strawberry (Fragaria 3 ananassa) cultivation predominates in regions with mild winters. In colder climates, overwintering hardiness is an essential trait for strawberry cultivation. Freezing injury of strawberry plants is one of the greatest factors in reducing crop yield and quality in temperate regions. Winter damage in Norway, for example, on average causes losses of 20%. Thus, production of cultivars with improved freezing hardiness is one of Norway's major objectives for their strawberry breeding programs. Improvement of cold hardiness is desirable for securing economic sustainability of the existing crops, and for expanding the growing regions of temperate fruit crops. Because strawberry is a representative species for the Rosaceae crops (e

“…4 DREB1 and DREB2 proteins share identity in the DNA binding domain, but are very little identical in the rest of the protein. 5 Because the DREB1 and DREB2 proteins are key regulators of the response to major abiotic stress, it is of high importance to understand how they are regulated. The regulation of DREB gene expression occurs in response to a stress, but also in basal conditions.…”

W e recently showed that-in Arabidopsis thaliana suspension cells-phosphoinositide dependent-phospholipase C (PI-PLC) and diacylglycerol kinase (DGK) negatively regulated the basal expression of most DREB2 genes. DREB2 genes encode transcription factors that bind to Drought Responsive Elements (DRE). Those elements are also bound by DREB1 factors. While DREB2 factors are mostly involved in drought and heat responses, DREB1s are induced in the response to chilling. We here show that the pharmacological inhibition of PI-PLC or DGK leads to the basal induction of DREB1 genes. However, the induction is much less marked for the DREB1 genes than that of DREB2A, a member of the DREB2 family. This illustrates that DREB1 and DREB2 genes, while having the same targets, are not submitted to the same transcription regulation, and that lipid signaling might in part explain these differences in the regulation of the DREB genes.
