“…By investigating the different concentrations of silver nitrate and different sampling times, the highest amount of stevioside was 33.33 mg/g DW observed at control condition 96 h after elicitation, while the highest amount of rebaudioside A was 2.19 mg/g DW obtained from 60 mg/L silver nitrate after 24 h of elicitation (Table 2). Jayalakshmi et al [21] reported that spraying silver nitrate on Malva sylvestris L. leaves increases anthocyanin production. Also, Vildova et al [24] showed that treating of Silybum marianum cell suspension culture increases taxifolin production.…”

“…The studies showed that cadmium chloride increased secondary metabolites production in Vitis vinifera cv. (V. vinifera cv) [16] , Chataranthus roseus [17] , Artemisia annua L. [18] , Glycine max L. (G. max L.) [19] and Salvia miltiorrhiza (S. miltiorrhiza) [20] and silver nitrate have been found to increase secondary metabolites production in Malva sylvestris L. [21] , Genista tinctoria L. [22] , Agastache rugosa (A. rugosa) [23] and Silybum marianum [24] . Therefore, in this study, we report for the first time the effect of cadmium chloride, silver nitrate and exposure times of elicitors on stevioside and rebaudioside A production and on Ent-kaurenoic acid 13-hydroxylase (KA13H), uridine diphosphate-glycosyltransferase 74G1 (UGT74G1) and uridine diphosphateglycosyltransferase 76G1 (UGT76G1) genes expression in S. rebaudiana (Bert.)…”

Tahmasi et al.: Cadmium chloride and silver nitrate effect on the Stevia rebaudiana (Bert.)Stevia rebaudiana (Bert.) produces steviol glycoside sweeteners that are sweeter than sucrose. Stevioside and rebaudioside A are important steviol glycosides used in food production. This study was conducted to investigate the effect of different concentrations of cadmium chloride (0, 20, 40, 60 and 80 mg/L) and silver nitrate (0, 15, 30, 45 and 60 mg/L) and different sampling times on stevioside and rebaudioside A production and Ent-kaurenoic acid 13-hydroxylase, uridine diphosphate-glycosyltransferase 74G1 and uridine diphosphate-glycosyltransferase 76G1 genes expression in in vitro conditions. The results showed that the application of cadmium nitrate and silver nitrate decreased stevioside and rebaudioside A production. Among various concentrations of cadmium chloride, the highest concentrations of stevioside and rebaudioside A were respectively 39.76 mg/g and 2.27 mg/L dry weight 96 and 72 h after elicitation with 20 mg/L cadmium chloride. Among different concentrations of silver nitrate, the highest amounts of stevioside and rebaudioside A were respectively 33.33 mg/g dry weight was 2.19 mg/L obtained at control condition after 96 h and elicitation with 60 mg/L for 24 h. In elicitation with cadmium chloride the expression all three genes were increased but silver nitrate elicitation increased uridine diphosphate-glycosyltransferase 76G1 gene expression and decreased the Ent-kaurenoic acid 13-hydroxylase and uridine diphosphateglycosyltransferase 74G1 genes expression. The correlation analysis showed that Ent-kaurenoic acid 13-hydroxylase gene expression was not correlated with uridine diphosphate-glycosyltransferase 74G1 and uridine diphosphate-glycosyltransferase 76G1 genes expression, while uridine diphosphateglycosyltransferase 74G1 was inversely correlated with uridine diphosphate-glycosyltransferase 76G1. Also, positive correlations were observed between uridine diphosphate-glycosyltransferase 74G1 gene expression with stevioside synthesis and uridine diphosphate-glycosyltransferase 76G1 gene expression with rebaudioside A.
