Abstract: Very little data about impact of simultaneous addition of selenium and iodine on plants exists. Plants of common buckwheat Fagopyrum esculentum Moench. were grown outdoors and were foliarly treated at the beginning of the flowering with different forms of Se (selenite, selenate) and I (iodide, iodate) and their combinations. Plants were harvested and seeds were collected and grounded, and the concentrations of fagopyrin and rutin were determined. Nor Se, nor I, alone or their combination had an influence on the concentration of fagopyrin. Selenium, iodine and their combination affected the amount of rutin in common buckwheat grain.

Abstract: Selenium in the form of selenate (Se VI) was foliarly applied to buckwheat plants to evaluate its influence on the uptake and accumulation of other selected elements, including copper (Cu), zinc (Zn), sulfur (S), molybdenum (Mo), iron (Fe), manganese (Mn), and cadmium (Cd). Among these, Cu, Zn, Mo, Fe, and Mn are essential elements while cadmium, on the other hand, is a toxic pollutant absorbed by plants from contaminated soils. Foliar selenium (VI) application resulted in modest changes in the concentrations of Cd, Mo, Fe, Mn, and S in the leaves; Cu in the husks; and Mo and Mn in inflorescences. However, selenium had no significant effect on Zn accumulation. These results suggest that foliar application of selenium (VI) may both enhance and inhibit the uptake of specific elements, with effects varying by plant tissue.

Abstract: Common buckwheat and Tartary buckwheat are pseudocereals and grow worldwide. Due to the high concentration of flavonoids, buckwheats are potential sources of smart food. Tartary and common buckwheat are traditionally grown in mountain regions of China, Korea, the northern parts of India, Bhutan, and Nepal. Plants that grow in high elevations are exposed to intense UV radiation, which can harm susceptible sites in the plants. Plants defend themselves against intense radiation by synthesising UV-absorbing compounds. Drought will probably become more frequent and intense due to climate change. UV radiation and drought are environmental parameters that present stress to the plants. These impacts can be synergistic or antagonistic. Selenium (Se) and silicon (Si) can protect plants exposed to UV radiation or drought since Se acts as an antioxidant. Silicon is an abundant element in Earth’s crust. It is present as a liquid or an amorphous or crystalline solid phase in the soil. Selenium and silicon are not essential elements for vascular plants, but they may positively affect plants. Thus, they can be added to the growth media to improve crop yield and quality, enhance resistance to  biotic and biotic stress and improve plant growth.

Abstract: The antigenotoxic effects of methanolic extracts of Tartary (Fagopyrum tataricum Gaertn.) and common buckwheat (Fagopyrum esculentum Moench) flour were evaluated against acrylamide-induced DNA damage. Acrylamide, a toxic food contaminant, was first identified in 2002 following its detection in Swedish food products. Our findings demonstrate that extracts from both buckwheat species significantly reduced DNA strand breaks. Tartary buckwheat contains higher levels of rutin, quercetin, and polyphenols, and exhibits greater antioxidant activity compared to common buckwheat. Due to endogenous rutin-degrading glucosidase activity, part of the rutin was enzymatically converted into quercetin. Processing generally decreased antioxidant activity, with the exception of wheat bread, where a slight increase was observed, likely attributed to Maillard reaction products. We confirmed that acrylamide induces genotoxic effects in HepG2 cells at all tested concentrations (0.3125, 0.625, 1.25, and 2.5 mM) after 24 hours of exposure, and that methanolic buckwheat extracts effectively reduced the formation of acrylamide-induced DNA damage. The extract from Tartary buckwheat demonstrated the highest antigenotoxic activity, surpassing even pure rutin or quercetin at higher concentrations. These results suggest that although thermal processing can generate potentially harmful compounds, such as acrylamide, food matrices may simultaneously contain bioactive components capable of counteracting or mitigating such adverse effects.
