“…By accumulating PR proteins during cold acclimation, overwintering plants may acquire a systemic, non-specific, pre-emptive defence against pathogens and exhibit greater disease resistance species and contribute to increased membrane stabilization (Bohnert and Sheveleva 1998). Sugar signalling is also closely associated with hormone signalling, the control of growth and development, and stress responses in plants (Zeng et al 2011). Depending on the plant species, various forms of soluble sugars are involved in physiological reactions to cold stress.…”

Apart from water availability, low temperature is the most important environmental factor limiting the productivity and geographical distribution of plants across the world. To cope with cold stress, plant species have evolved several physiological and molecular adaptations to maximize cold tolerance by adjusting their metabolism. The regulation of some gene products represents an additional mechanism of cold tolerance. A consequence of these mechanisms is that plants are able to survive exposure to low temperature via a process known as cold acclimation. In this review, we briefly summarize recent progress in research and hypotheses on how sensitive plants perceive cold. We also explore how this perception is translated into changes within plants following exposure to low temperatures. Particular emphasis is placed on physiological parameters as well as transcriptional, post-transcriptional and post-translational regulation of cold-induced gene products that occur after exposure to low temperatures, leading to cold acclimation.

“…Gene expression analysis revealed that expression of the genes encoding chloroplastic enzymes of sugar metabolism was significantly up-regulated in the tillering nodes (Zeng et al, 2011) at low temperatures. More recent proteomics studies in tillering nodes of hardy winter wheat grown under field conditions revealed that five groups of proteins significantly increased in response to À30°C freezing stress.…”

“…The reported yield loss in winter wheat caused by spring freeze injury varies from 14 to 85% (Zhong et al, 2008). The yield reduction may be attributed to freeze induced damage to spike development (Kang et al, 2013); impairment of photosynthesis (Thakur and Nayyar, 2013); decreases in shoot biomass, flag leaf size, and specific leaf area (Valluru et al, 2012); and altered carbohydrate metabolism (Zeng et al, 2011; Theocharis et al, 2012).…”

Spring freeze events seriously limit the growth, development, and grain yield of winter wheat (Triticum aestivum L.). A 2-yr eld experiment with two contrasting cultivars: XM21 (low-temperature resistant) and XZ24 (low-temperature sensitive), was conducted using an air temperature control device designed to allow investigation of the physiological and grain yield responses to spring freeze. e plants were grown in the eld and subjected to a 5-d spring freeze episode (approximately 8°C lower than the ambient temperature) at jointing stage (Zadoks scale 31). Spring freeze signi cantly decreased gas exchange rates and maximum quantum e ciency of photosystem II in wheat leaves of both cultivars. Under spring freeze, the yield loss was 12 to 14% in XZ24 vs. 5 to 6% in XM21. Greater yield loss in XZ24 coincided with a greater reduction of tiller and spike number in XZ24 than in XM21. Spring freeze occurring at jointing stage depressed the photosynthetic capacity of the leaves when measured at the end of the 5-d period and again at 7 d later, resulting in lowered number of e ective tillers, and eventually decreasing the grain yield. e genetic and/or bio-physiochemical basis for the di erent sensitivity of tiller development to spring freeze between the two cultivars could be further exploited for breeding new wheat cultivars tolerant to spring freeze stress.
