“…A similar gene cluster at the orthologous region on chromosome 5A in diploid wheat (Triticum monococcum) is also located at the Fr-A m 2 frost resistance QTL for the level of transcription of the cold-regulated gene COR14b at 15 C. (Snape et al 2001;Vágújfalvi et al 2003;Miller et al 2006). The locus for frost tolerance was shown to be completely linked to the central gene cluster (Cbf-14, -15, -12;Sandve et al 2011;Tondelli et al 2011).…”

Abstract. The United Nations Food and Agriculture Organisation (FAO) forecasts a 34% increase in the world population by 2050. As a consequence, the productivity of important staple crops such as cereals needs to be boosted by an estimated 43%. This growth in cereal productivity will need to occur in a world with a changing climate, where more frequent weather extremes will impact on grain productivity. Improving cereal productivity will, therefore, not only be a matter of increasing yield potential of current germplasm, but also of improving yield stability through enhanced tolerance to abiotic stresses. Successful reproductive development in cereals is essential for grain productivity and environmental constraints (drought, cold, frost, heat and waterlogging) that are associated with climate change are likely to have severe effects on yield stability of cereal crops. Currently, genetic gains conferring improved abiotic stress tolerance in cereals is hampered by the lack of reliable screening methods, availability of suitable germplasm and poor knowledge about the physiological and molecular underpinnings of abiotic stress tolerance traits.

“…Light factors during the cold acclimation period can affect the freezing tolerance of herbaceous overwintering plants in several ways [34,35]. Firstly, a certain irradiance combined with low temperature increases photosystem II (PSII) excitation pressure, which is a signal leading to the development of freezing resistance [36][37][38][39][40]. Secondly, short photoperiod and low red to far red light (R:FR) ratio can interact with low temperature to stimulate the development of freezing resistance [41][42][43][44].…”

“…Secondly, short photoperiod and low red to far red light (R:FR) ratio can interact with low temperature to stimulate the development of freezing resistance [41][42][43][44]. Thirdly, irradiance is the energy source for the accumulation of carbohydrates with a functional role in freezing resistance [40]. In addition, irradiance is the energy source for the accumulation of carbohydrate reserves needed for maintenance and stress responses during winter, as well as for early regrowth in spring.…”

“…In regions with a long winter, a storage of organic reserves, particularly carbohydrates, are necessary for maintenance respiration, stress responses, and early spring regrowth. In addition, carbohydrates have specific roles as osmolytes and protectants of cellular components [13,40], and winter survival ability is often associated with a higher concentration of both simple sugars and fructans in the basal parts of the shoot attained during cold acclimation [64][65][66][67]. As described above, winter cereals maintain CO 2 -fixation rates at low temperatures due to photosynthetic acclimation, a mechanism, which combined with restrictions on leaf growth, ensures that a storage of carbohydrates is accumulating.…”

Optimal Regulation of the Balance between Productivity and Overwintering of Perennial Grasses in a Warmer Climate

Seasonal growth patterns of perennial plants are linked to patterns of acclimation and de-acclimation to seasonal stresses. The timing of cold acclimation (development of freezing resistance) and leaf growth cessation in autumn, and the timing of de-acclimation and leaf regrowth in spring, is regulated by seasonal cues in the environment, mainly temperature and light factors. Warming will lead to new combinations of these cues in autumn and spring. Extended thermal growing seasons offer a possibility for obtaining increased yields of perennial grasses at high latitudes. Increased productivity in the autumn may not be possible in all high latitude regions due to the need for light during cold acclimation and the need for accumulating a carbohydrate storage prior to winter. There is more potential for increased yields in spring due to the availability of light, but higher probability of freezing events in earlier springs would necessitate a delay of de-acclimation, or an ability to rapidly re-acclimate. In order to optimize the balance between productivity and overwintering in the future, the regulation of growth and acclimation processes may have to be modified. Here, the current knowledge on the coordinated regulation of growth and freezing resistance in perennial grasses is reviewed.

The grass family Poaceae is among the largest and most successful plant families, both ecologically and economically. It covers a wide geographic, climatic, and ecological range and contains many of the world's most important crops including wheat, barley, rice, maize, and sorghum, as well as many forage and biofuel species. Both wild and cultivated grasses are diverse in areas that regularly experience cold and freezing as well as high seasonality, harsh winters, and short growing seasons. Grasses growing in these environments have evolved an arsenal of strategies to tolerate or resist cold stress, or to escape the cold by phenological adjustments. Here, we review the current knowledge of cold adaptations in grasses synthesising across the disciplines of stress physiology, genetics, metabolomics, ecology, and evolution, in both wild and cultivated species. Specifically, we explore what is known about molecular and physiological cold stress responses, how these might have evolved and their role in shaping diversification and distribution patterns of grasses. We argue that integrating insights from multiple disciplines will further our understanding of cold adaptation.
