Stevia rebaudiana Bertoni has been promoted for having sweet leaves as well as pharmaceutical and industrial properties. The sweet taste of Stevia leaves is due to the presence of steviol glycosides (a group of diterpene glycosides) found in a small number of plants. In the biosynthetic pathway of steviol glycosides (SGs), 15 enzymes that express the genes are associated with these enzymes under the influence of the elicitors. Due to the individuality of the stevia and few studies on the biosynthesis pathway of SGs, this paper attempted to investigate the effects of some of the elicitors, including methyl jasmonate (MeJA), salicylic acid (SA), auxins (Aux), cytokinins (CKs), gibberellins (GAs) and its inhibitors including paclobutrazol (BPZ) and chloroquate (CCC)), on the responsible genes for the biosynthesis of SGs. Some of these elicitors, including MeJA, SA and GA have great potential in increasing secondary metabolites. Moreover, the biosynthetic pathway of GAs and SGs are shared till ent-kaurenoic acid (ent-KA) biosynthesis, which raises the question of whether this hormone and its inhibitors are effective in the SGs biosynthesis.

The One

Selenium (Se) enrichment of Stevia rebaudiana Bertoni can serve a dual purpose, on the one hand to increase plant biomass and stress tolerance and on the other hand to produce Se fortified plant-based food. Foliar Se spraying (0, 6, 8, 10 mg/L selenate, 14 days) of Stevia plantlets resulted in slightly decreased stevioside and rebaudioside A concentrations, and it also caused significant increment in stem elongation, leaf number, and Se content, suggesting that foliar Se supplementation can be used as a biofortifying approach. Furthermore, Se slightly limited photosynthetic CO2 assimilation (AN, gsw, Ci/Ca), but exerted no significant effect on chlorophyll, carotenoid contents and on parameters associated with photosystem II (PSII) activity (FV/FM, F0, Y(NO)), indicating that Se causes no photodamage in PSII. Further results indicate that Se is able to activate PSI-cyclic electron flow independent protection mechanisms of the photosynthetic apparatus of Stevia plants. The applied Se activated superoxide dismutase (SOD) isoenzymes (MnSOD1, FeSOD1, FeSOD2, Cu/ZnSOD1, Cu/ZnSOD2) and down-regulated NADPH oxidase suggesting the Se-induced limitation of superoxide anion levels and consequent oxidative signalling in Stevia leaves. Additionally, the decrease in S-nitrosoglutathione reductase protein abundance and the intensification of protein tyrosine nitration indicate Se-triggered nitrosative signalling. Collectively, these results suggest that Se supplementation alters Stevia shoot morphology without significantly affecting biomass yield and photosynthesis, but increasing Se content and performing antioxidant effects, which indicates that foliar application of Se may be a promising method in Stevia cultivation.
