“…Indeed, a higher activity of adenosine 5¢-phosphosulfate sulfotransferase, the regulatory enzyme of sulfate reduction, was found in maize during lowtemperature stress, resulting in an increased cysteine level (Kocsy et al 1996). Low-temperature stress also induced an increase in glutamate and glycine (Szalai et al 1997). Similar to the results obtained in maize, low temperature increased the rate of cysteine biosynthesis in wheat as shown in the sulfate-labelling experiments presented here.…”

The effect of cold hardening on the accumulation of glutathione (GSH) and its precursors was studied in the shoots and roots of wheat (Triticum aestivum L.) cv. Cheyenne (Ch, frost-tolerant) and cv. Chinese Spring (CS, moderately frost-sensitive), in a T. spelta L. accession (Tsp, frost-sensitive) and in chromosome substitution lines CS (Ch 5A) and CS (Tsp 5A). The fast induction of total glutathione accumulation was detected during the first 3 d of hardening in the shoots, especially in the frost-tolerant Ch and CS (Ch 5A). This observation was corroborated by the study of de novo GSH synthesis using [(35)S]sulfate. In Ch and CS (Ch 5A) the total cysteine, gamma-glutamylcysteine (precursors of GSH), hydroxymethylglutathione and GSH contents were greater during the 51-d treatment than in the sensitive genotypes. After 35 d hardening, when the maximum frost tolerance was observed, greater ratios of reduced to oxidised hydroxymethylglutathione and glutathione were detected in Ch and CS (Ch 5A) compared to the sensitive genotypes. A correspondingly greater glutathione reductase (EC 1.6.4.2) activity was also found in Ch and CS (Ch 5A). It can be assumed that chromosome 5A of wheat has an influence on GSH accumulation and on the ratio of reduced to oxidised glutathione as part of a complex regulatory function during hardening. Consequently, GSH may contribute to the enhancement of frost tolerance in wheat.

“…Other non-protein amino acids such as GABA and glycine betaine may be detected in the free amino acid pool under cold stress, as well as (Palma et al, 2014;Shelp et al, 2012). Increasing of 13 different amino acids and putrescine has been reported from maize under chilling condition (Janmohammadi et al, 2015;Szalai et al, 1997). In the present work, increasing of Bradford total protein and free amino acids contents was revealed in the s tevia plants treated with 4 °C cold combined with polyamines.…”

Stevia rebaudiana Bertoni is a perennial medicinal herb indigenous to tropical regions of South America. The present study evaluated some physiological changes of the plant under cold in the absence and the presence of polyamine conditions. The results showed photosynthetic pigments and photochemical efficiency of PSII reduced in cold treatment conditions than control, significantly. However, a considerable increase in the parameters was observed in all of polyamine treated goups. Leaf compatible solutes such as proline and glycine betaine that were not shown significantly increasing at cold treatment groups, elevated in the 2 days cold-polyamine-treated group. The similar results were seen for free amino acid and total protein contents of the treated plants. It was also revealed that specific activity of some antioxidant enzymes such as catalase and ascorbate peroxidase increased in cold-treated or cold + polyamine-treated groups than related controls. It caused a significant decrease in H 2 O 2 and malondialdehyde contents of the treated plants. The results indicated an increasing in saturated long chain fatty acids after 4 days of cold at 4 °C. It was concluded that the polyamine supplement can induced a considerable tolerance in stevia plants at cold condition.

“…It has been demonstrated that hardening is much less effective in the dark than under normal light conditions (Janda et al, 2014). However, exposure of plants to low temperatures also enhances the level of photoinhibition, which does not only impair the the photosynthetic machinery, but may also modify other stress-related processes (Szalai et al, 1997). Contrary to bread wheat, Szűcs et al (1999) observed that four to six weeks are necessary for the development of adequate cold-hardiness in durum wheat.…”

(I. Majláth). 2 SUMMARYThe rate of carbon and nitrogen assimilation is highly sensitive to stress factors, such as low temperature and drought. Little is known about the role of light in the simultaneous effect of cold and drought. The present study thus focused on the combined effect of mild water deficiency and different light intensities during the early cold hardening in durum wheat (Triticum turgidum ssp. durum L.) cultivars with different levels of cold sensitivity. The results showed that reduced illumination decreased the undesirable effects of photoinhibition in the case of net photosynthesis and nitrate reduction, which may help to sustain these processes at low temperature. Mild water deficiency also had a slight positive effect on the effective quantum efficiency of PSII and the nitrate reductase activity in the cold. Glutamine synthesis was affected by light rather than by water deprivation during cold stress. The invertase activity increased to a greater extent by water deprivation, but an increase in illumination also had a facilitating effect on this enzyme. This suggests that both moderate water deficiency and light have an influence on nitrogen metabolism and sucrose degradation during cold hardening. A possible rise in the soluble sugar content caused by the invertase may compensate for the decline in photosynthetic carbon assimilation indicated by the decrease in net photosynthesis. The changes in the osmotic potential can be also correlated to the enhanced level of invertase activity. Both of them were regulated by light at normal water supply, but not at water deprivation in the cold. However, changes in the metabolic enzyme activities and osmotic adjustment could not be directly contributed to the different levels of cold tolerance of the cultivars in the early acclimation period.
