“…Many studies investigating plant responses to cold stress have been reported [12–17]. Numerous cold-responsive genes have been identified from different species, including Arabidopsis thaliana [2, 18], Oryza sativa [19–22], Zea mays [23, 24], Prunus persica [25, 26], and many other species [13, 27–30]. At present, the best-understood genetics network associated with a role in cold acclimation is the Arabidopsis CBF cold response pathway [31].…”

BackgroundCB-1 and K326 are closely related tobacco cultivars; however, their cold tolerance capacities are different. K326 is much more cold tolerant than CB-1.ResultsWe studied the transcriptomes and metabolomes of CB-1 and K326 leaf samples treated with cold stress. Totally, we have identified 14,590 differentially expressed genes (DEGs) in CB-1 and 14,605 DEGs in K326; there was also 200 differentially expressed metabolites in CB-1 and 194 in K326. Moreover, there were many overlapping genes (around 50%) that were cold-responsive in both plant cultivars, although there were also many differences in the cold responsive genes between the two cultivars. Importantly, for most of the overlapping cold responsive genes, the extent of the changes in expression were typically much more pronounced in K326 than in CB-1, which may help explain the superior cold tolerance of K326. Similar results were found in the metabolome analysis, particularly with the analysis of primary metabolites, including amino acids, organic acids, and sugars. The large number of specific responsive genes and metabolites highlight the complex regulatory mechanisms associated with cold stress in tobacco. In addition, our work implies that the energy metabolism and hormones may function distinctly between CB-1 and K326.ConclusionsDifferences in gene expression and metabolite levels following cold stress treatment seem likely to have contributed to the observed difference in the cold tolerance phenotype of these two tobacco cultivars.Electronic supplementary materialThe online version of this article (doi:10.1186/s12864-017-3871-7) contains supplementary material, which is available to authorized users.

“…Most studies support the notion that nitrate supply has a negative effect on the biosynthesis of phenolics and vitamin C, as well as antioxidant activity (Lee and Kader, 2000 ; Awad and de Jager, 2002 ; Staugaitis et al, 2008 ; Ibrahim et al, 2012 ; Yañez-Mansilla et al, 2014 ). However, recent evidence suggests glycine enhances tolerance to salinity (Badran et al, 2015 ), drought stress (Yang N. et al, 2016 ) and cold temperatures (Cao et al, 2017 ) via elevating the reactive oxygen species (ROS) scavenging system, nitrogen uptake and photosynthesis. In addition, glycine promotes the accumulation of carbohydrates (sucrose, glucose, fructose), which can provide a source of energy and carbon rings for polyphenol biosynthesis (Liu et al, 2016 ).…”

Exogenous Glycine Nitrogen Enhances Accumulation of Glycosylated Flavonoids and Antioxidant Activity in Lettuce (Lactuca sativa L.)

Glycine, the simplest amino acid in nature and one of the most abundant free amino acids in soil, is regarded as a model nutrient in organic nitrogen studies. To date, many studies have focused on the uptake, metabolism and distribution of organic nitrogen in plants, but few have investigated the nutritional performance of plants supplied with organic nitrogen. Lettuce (Lactuca sativa L.), one of the most widely consumed leafy vegetables worldwide, is a significant source of antioxidants and bioactive compounds such as polyphenols, ascorbic acid and tocopherols. In this study, two lettuce cultivars, Shenxuan 1 and Lollo Rossa, were hydroponically cultured in media containing 4.5, 9, or 18 mM glycine or 9 mM nitrate (control) for 4 weeks, and the levels of health-promoting compounds and antioxidant activity of the lettuce leaf extracts were evaluated. Glycine significantly reduced fresh weight compared to control lettuce, while 9 mM glycine significantly increased fresh weight compared to 4.5 or 18 mM glycine. Compared to controls, glycine (18 mM for Shenxuan 1; 9 mM for Lollo Rossa) significantly increased the levels of most antioxidants (including total polyphenols, α-tocopherol) and antioxidant activity, suggesting appropriate glycine supply promotes antioxidant accumulation and activity. Glycine induced most glycosylated quercetin derivatives and luteolin derivatives detected and decreased some phenolic acids compared to nitrate treatment. This study indicates exogenous glycine supplementation could be used strategically to promote the accumulation of health-promoting compounds and antioxidant activity of hydroponically grown lettuce, which could potentially improve human nutrition.

“…Several studies have found that plants experience reduced photosynthetic activity when exposed to cold temperatures. For example, Xiaochuang et al (2017) found that rice plants subjected to N application before treatments at low temperatures had a significant reduction in their photosynthetic rates. Similarly, Dalmannsdottir et al (2017) found that photosynthetic activity in perennial ryegrass (Lolium perenne) and timothy (Phleum pratense) was reduced after exposure to low temperatures, under natural conditions in autumn.…”

Low temperatures affect avocado plants and their response varies across genetic variants. The objective of this study was to assess cold stress of avocado cultivars based on visual, physiological, and biochemical criteria for evaluating freezing injury in these plants. The avocado cultivars 'Geada,' 'Fortuna,' 'Fuerte,' 'Quintal,' 'Margarida,' and 'Primavera' were subjected to temperatures of −2.5, −4.0, −5.0, and −6.0 °C for 1 h in a growth chamber. Their responses to cold stress were evaluated on the basis of visual damage score, photosynthetic rate, water pressure potential, protein content and enzymatic activity. Moreover, the experimental design was factorial and completely randomized with four replicates of each cultivar. An analysis of variance of the results was performed and the means were compared using Tukey's post-hoc test (p <0.05). Evaluations based on the plants water pressure potential, total protein content, catalase activity, photosynthetic rate, and visual damage score were efficient in estimating the effects of cold stress in avocado plants. Additionally, photosynthesis and visual damage score were significantly correlated in all evaluations, enabling classification of the cultivars in terms of response to cold stress. We found that Fuerte was the most tolerant cultivar followed by Geada. The Primavera was the most sensitive cultivar.
