“…These results suggest that anthocyanin is an important flavonoid as a modulator of salinity stress and plays an important role in the prevention of stress-induced oxidative damage in leaves of almost all rice varieties except for the salttolerant BC2F7#62-56. These results were supported by Eryılmaz 29 , reporting that there was a correlation in the increases of anthocyanins with salt stress in tomato and red cabbage seedlings.…”

This study was designed to determine the anthocyanin cyanidin-3-glucoside content and antioxidant activity of rice varieties under salinity stress. Two classes of Thai rice lines: cyanic (Riceberry, Kham, and Khamdoisaket) and acyanic (KDML 105, Sinlek, were hydroponically grown. Seedlings were grown for 16 days and were supplied with salinity nutrient solution with 0 (control) and 60 mM NaCl for 11 days. The total phenolic content and the antioxidant activity, including 2,2-diphenyl-1-picrylhydrazyl free radical-scavenging, ferric reducing antioxidant power, and lipid peroxidation were also determined by colorimetric assay. Anthocyanin pigment cyanidin-3-glucoside was quantified by high performance liquid chromatography. The results show that salinity stress in Khamdoisaket and KDML 105 cultivars significantly (p < 0.05) increased the total phenolic content, antioxidant activity, and cyanidin-3-glucoside content. Riceberry, Kham, and Sinlek cultivars, showed a moderate increase. The salt tolerant variety, BC2F7#62-56, showed only a slight but not significant increase in antioxidant activity and virtually unchanged lipid peroxidation, total phenolic content, and anthocyanin cyanidin-3-glucoside content under salinity stress. These results suggest that the increased total phenolic content, antioxidant activity, and anthocyanin cyanidin-3-glucoside content in rice seedling might be a protection mechanism against salinity stress. BC2F7#62-56 seems to have potential tolerance to salinity stress. This capability could be related to unchanged antioxidant activities, lipid peroxidation, total phenolic content, and anthocyanin cyanidin-3-glucoside content.

“…Chlorophyll and carotenoid levels are considered to be indicators of salt stress in plants. Because the levels of the main photosynthetic pigments, chlorophyll a, chlorophyll b, and carotenoids, are significantly affected by salt stress, these are used as parameters to select tolerant and sensitive cultivars of crop plants (Eryilmaz, 2007;Rahdari et al, 2012). Besides, the level of MDA is a measure of membrane lipid peroxidation damage caused by abiotic stresses and it is an important indication of oxidative damage under conditions of salt stress (Liang et al, 2003).…”

ABSTRACT. Salinity is a major environmental stress to plants. In this study, the ability of plants to tolerate salt was investigated by studying growth, physiological characteristics, and expression levels of genes related to the salt-stress response in the salt-tolerant rice mutant (Till-II-877), which was derived from γ-ray irradiation. Compared to plants grown under normal conditions, the height and root length of wild type (WT) were reduced by approximately 40 and 29% following exposure to salt stress for 3 weeks, whereas Till-II-877 line showed 29 and 23% reductions in plant height and root length, respectively. No significant changes were observed in total chlorophyll content, and the malondialdehyde content of the mutant increased less than that of the WT under salt treatment. Gene expression was compared between the WT and mutant lines using microarray analysis. An unbiased analysis of the gene expression datasets allowed us to identify the pathways involved in salt-stress responses. Among the most significantly affected pathways, changes in gene expression were observed in α-linolenic acid and linoleic acid metabolism (in lipid metabolism), fructose and mannose metabolism and glycolysis-gluconeogenesis (in carbohydrate metabolism), cysteine and methionine metabolism (in amino acid metabolism), and carbon fixation (in the energy metabolism of photosynthetic organisms) under salt stress. These results show that the differential response of plants subjected to salt stress was due to changes in multiple metabolic pathways. These findings increase our understanding of the effects of salt stress in rice and may aid in the development of salt-tolerant rice cultivars.

“…Moreover, the reduction in photosynthetic pigments (chlorophyll a, chlorophyll b, and total carotenoids) due to salinity effect which attributed to the disturbance of ions absorption involved in chloroplast formation and protein synthesis and/or plastid breakdown (Abd El-Wahab, 2006). However, it was observed that the degradation of chlorophyll pigments was increased as a result of exposure to NaCl (Eryilmaz, 2006). Table (3) showed that medium with 5 mg/l Phenylalanine and free from sodium chloride gave the highest values of total chlorophyll content (390.79) in shootlets, while medium with 10 mg/l Phenylalanine and free from sodium chloride gave the lowest value of total chlorophyll content (10.83) in callus.…”

The present study was conducted at the Tissue Culture and Plant Micropropagation Laboratory of Floriculture, Ornamental Horticulture and Landscape Gardening Department, Faculty of Agriculture, Alexandria University, during 2014 and 2015, to study the effect of five different concentrations of phenylalanine (0, 0.5, 5, 10, and 15 mg/l) and four different concentrations of sodium chloride (0, 2000, 4000 and 6000 mg/l) on the production of some secondary metabolites in in vitro cultures of Mentha longifolia using shoot tips and leaves.Leaf segments about 1 cm 2 and shoot tips consisting of 3-4 cm long stem segments containing three auxiliary buds (as explants) were planted on MS medium supplemented with NAA (0.25 mg/l) + BAP(2.5 mg/l ) + 30 g/liter sucrose + 7 g/liter agar for shoot regeneration from shoot tips, while MS medium contained 2,4-D (4 mg/l) + BAP (0.5 mg/l ) for callus induction from leaf segments, the pH was adjusted to 5.8±0.02. Plantlets were subjected to 16 hours light and 8 hours darkness (2000-2500 lux for 16 h/d provided by fluorescent tubes), the temperature was adjusted at 25º C ± 2 and 60-70% humidity. The cultures were incubated for 60 days in case of shoot tips and 100 days in case of leaves for callus induction. Chemical analysis was performed on callus tissues after 60 and 100 days from planting and shoot tissues after 60 days from planting which were produced under salinity levels, phenylalanine levels and their interaction to determine the contents of total chlorophyll, total phenolic, rosmarinic acid and proline in both tissues.From the obtained results in this study, using shoot tips for the production of phenolic acid and rosmarinic acid was superior than the callus. Low concentration of sodium chloride (2000 mg /l) enhanced the production of some secondary metabolites. However high concentrations of sodium chloride (6000 mg /l) leads to slow growth, yellowing of cells and sometimes the deterioration of plants. Uses of intermediate concentrations of phenylalanine (5 and 10 mg /l) enhanced the production of chlorophyll and some secondary metabolites where as high concentration (15 mg /l) does not stop growth and cell division.
