At the early period of studying the effects of low temperature on chilling-sensitive plants (second half of XIX century), Saks' theory of plants death due to disorders in water regime was widely accepted. However, subsequent studies revealed narrowness of such interpretation of these data. Changes in water regime appeared to be the consequence rather than the main cause of the chilling injury [1]. In the middle of XX century, Zholkevich found that wilting of aerial organs resulted from the loss of water-retaining capacity, caused by alterations in the cytoplasm structure and a misbalance of metabolism, rather than from excessive transpiration at a slow water supply from roots [2].Based on observations of protoplasm viscosity at decreasing temperature, Belehradek (1935, cited after [1]) suggested that the viscosity plays a key role in chilling injury. The lower is the chill tolerance of a plant, the higher is the temperature at which "gelation" occurs, and the faster is the rise in the cytoplasm viscosity. A considerable increase in viscosity slows down biochemical reactions in the cytoplasm and disturbs metabolism, which leads to physiological disorders in nutrition, respiration, and growth. However, Zholkevich showed that the cytoplasm viscosity in cucumber plants decreased with the duration of chilling period, reaching the lowest value after 2.5-4 days. Thereafter, the viscosity gradually increased to the level characteristic of unchilled plants and could even exceed this level shortly before the plant death [2]. In severely damaged plants, the viscosity continued to increase after transferring the plants to warmth. According to the author's view [2], the increase in viscosity before the plant death represents the final degradation stage, unrelated to the first stage of injury; it aggravates injury, even after the transfer of plants to warmth.According to some papers published in the 1950-1960s, the more general cause of injury of chilling-sensitive plants subjected to prolonged chilling resides in metabolic disorders. The death of chilling-sensitive plants at chilling temperatures was supposedly related to the prevalence of degradation over synthesis. A disbalance between energy production by respiration and its effective consumption was thought to be a possible cause for changes in the cytoplasm structure and irreversible shifts in metabolism [1]. However, metabolic changes become apparent only at sufficiently long chilling periods and, similarly to changes in water regime, could not be the primary cause of chilling injury in most cases. It was shown that short intervals of chilling treatment do not drastically retard metabolism [3]. Accumulation of toxic metabolites due to disbalance in metabolism, which takes place during cooling of chilling-sensitive plants (toxic effect was considered one of the main causes of chilling injury [1, 2]), often occurs only after the transfer of chilled tissues to optimal conditions [4]; i.e., it is a result of secondary dysfunction, related to warming.Among the hypotheses on...

“…Changes in gene expression and protein synthesis associated with the induction of freezing tolerance during cold acclimatization have been well documented [1,6]. Oxidative damage is considered to be an early response of sensitive tissues to chilling injury [7]. Free radical production in thylakoid membranes of leaves in low-temperature-treated plants has been observed prior to appearance of chilling injury [8].…”

The ability of iron to accept and donate electrons makes it important for plant growth, but it can also damage plants when they are under environmental stress. Ferritin, a protein encoded by the gene Fer, catalyzes the oxidation of Fe(2+) and subsequent storage of Fe(3+) within the mineral core. Ferritin may reduce the adverse effects of iron on Chorispora bungeana Fisch. & C.A. May during the course of cold stress. C. bungeana is a rare alpine subnival plant species that is highly resistant to a freezing environment. We have isolated and characterized the ferritin cDNA (CbFer) from C. bungeana. It is 975 bp in length with an open reading frame of 260 amino acids, corresponding to a protein of predicted molecular mass of 29.17 kDa and an isoelectric point of 5.44. Amino acid analysis of the polypeptides indicated that CbFer codes for a ferritin subunit plus a chloroplast-targeting transit peptide. Reverse transcription polymerase chain reaction analysis confirmed that CbFer was a tissue-specific gene since the expression could only be detected in leaves. The gene expression patterns were investigated in relation to cold stress (4 degrees C and -4 degrees C) and to various exogenous signals, including excessive iron, hydrogen peroxide (H(2)O(2)), and nitrogen monoxidum (NO). The amount of CbFer mRNA increased in response to low temperatures and gene expression at -4 degrees C was both more distinct and quicker than that at 4 degrees C. Two exogenous signals, excessive iron and H(2)O(2), upregulated the expression of the CbFer gene, but NO had no effect. The CbFer gene may play an important role in response to cold stress, while the expression of the gene during stress may be influenced by major and minor factors such as iron and H(2)O(2), respectively.

“…Oxidative damage, caused by an imbalance in any cell compartment in the production of ROS and antioxidant defense (Ogweno et al 2008), is considered to be an early response of sensitive tissues to chilling (Hariyadi and Parkin 1991). For instance, free radical production in thylakoid membranes of leaves in low temperature treated plants has been observed prior to chilling injury appearing (Hidey and Bjorn 1996).…”

Brassinosteroids alleviate chilling-induced oxidative damage by enhancing antioxidant defense system in suspension cultured cells of Chorispora bungeana

Brassinosteroids (BRs), a class of plant steroid hormones, play a significant role in the amelioration of various biotic and abiotic stresses. In order to further explore and elaborate their roles in plants subjected to chilling stress, suspension cultured cells of Chorispora bungeana with or without 24-epibrassinolide (EBR) application were exposed to 4 and 0°C for 5 days. The EBR treated cells exhibited higher viability after exposure to low temperatures compared with the control. Under chilling stress, reactive oxygen species (ROS) levels and lipid peroxidation were increased in the cultured cells, which were significantly inhibited by EBR application. The activities of antioxidative enzymes such as ascorbate peroxidase (APX), catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) were increased during chilling treatments, and these increases were more significant in the EBR applied suspension cells. The EBR treatment also greatly enhanced contents of ascorbic acid (AsA) and reduced glutathione (GSH) under chilling stress. From these results, it can be concluded that EBR could play the positive roles in the alleviation of oxidative damage caused by ROS overproduction through enhancing antioxidant defense system, resulting in improving the tolerance of C. bungeana suspension cultures to chilling stress.
