Previous studies on cold-triggered events leading to Ca2+ influx during cold acclimatization have been conducted on either unicellular cyanobacterium Synechocystis or plant cell suspensions, and used transcript levels of cold-induced genes as end-point markers. Whether the results of these studies are valid for intact plants or their organs is not known.(More)
We propose that targeting the enhanced photosynthetic performance associated with the cold acclimation of winter cultivars of rye (Secale cereale L.), wheat (Triticum aestivum L.), and Brassica napus L. may provide a novel approach to improve crop productivity under abiotic as well as biotic stress conditions. In support of this hypothesis, we provide the(More)
Cold acclimation of winter cereals and other winter hardy species is a prerequisite to increase subsequent freezing tolerance. Low temperatures upregulate the expression of C-repeat/dehydration-responsive element binding transcription factors (CBF/DREB1) which in turn induce the expression of COLD-REGULATED (COR) genes. We summarize evidence which indicates(More)
The effects of cold acclimation and long-term elevated CO2 on photosynthetic performance of wild-type (WT) and BnCBF17-over-expressing line of Brassica napus cv. Westar (BnCBF17-OE) grown at either 20/16 °C (non-acclimated) or 5/5 °C (cold acclimated) and at either ambient (380 μmol C mol−1) or elevated (700 μmol C mol−1) CO2 were studied. Compared with(More)

Enhancing biomass production and yield by maintaining enhanced capacity for CO 2 uptake in response to elevated CO 2. Can. J. Plant Sci. 94: 1075Á1083. Using four model plants, two members of the Gramineae, rye and wheat, and two Brassicaceae, Brassica napus and Arabidopsis thaliana, two fundamental approaches were exploited to determine how regulating(More)
