“…Zn is an activator and essential element for many enzymes, and protein synthesis is hindered when plants are deficient in Zn, leading to the accumulation of amino acids ( Shrivastav et al., 2020 ). The elevated Zn content in wheat grains caused by low-temperature may be due to the presence of Zn in super-oxide dismutase (SOD) and catalase (CAT), and an increase in Zn content can enhance the antioxidant capacity of plant cells ( Batova et al., 2021 ). Increases in Fe content may be due to cold-induced expression of Fe uptake-related genes, causing the root tips to actively secrete reducing substances such as H + , organic acids, and phenols into the root environment, thereby increasing the solubility of external Fe ( Zhang et al., 2019 ).…”

IntroductionThe nutritional value of wheat is important to human health. Despite minerals being essential nutrients for the human body, they are often neglected in consideration of the nutritional quality of cereal grains. Extreme low-temperature events have become more frequent due to the current environmental unpredictability, and it is yet unknown how the mineral components in grains are affected by low temperature.MethodsTo provide valuable information for enhancing the nutritional quality of wheat under potential climatic conditions, we treated different cold-sensitive wheat cultivars at four low-temperature levels during the individual and combined stages of jointing and booting in controlled-environment phytotrons. Results and DiscussionIn general, the contents of P, K, Ca, and Zn in the cold-sensitive cultivar (Yangmai16) and K in the cold-tolerant cultivar (Xumai30) were enhanced by low temperature. However, the accumulation of minerals in mature grains was reduced under low-temperature treatment, except for P, Ca, and Zn in Yangmai16. In addition, the mineral content and accumulation in Yangmai16 (except for Fe) were more susceptible to low temperature during the combined stages, while the mineral content and accumulation of K, Fe, and Zn in Xumai30 were more susceptible to low temperature during the booting stage. Moreover, Yangmai16 under extremely low temperatures (T3 and T4) during booting and Xumai30 under all low-temperature treatments during the combined stages had lower comprehensive evaluation values. These findings offer a crucial reference for enhancing the nutritional quality of wheat grains under climate change.

“…To protect themselves against developing oxidative stress, plants have an effective antioxidant defense system including enzymatic and non-enzymatic compounds [ 64 ]. The increase in activity of the main antioxidant enzymes in white mustard [ 26 ], rice [ 65 ], wheat [ 66 ], barley [ 67 ], etc. under Zn excess was demonstrated.…”

Zinc (Zn) is a fundamental micronutrient for plants’ metabolism, but in high concentrations, it is toxic. In this study, we investigated the physiological response of white mustard (Sinapis alba L. cv. Belgia) plants to the Zn excess concentrations (50, 100, and 150 mg kg−1) in the substrate. The results showed that sand Zn concentration of 50 mg kg−1 did not affect the physiological parameters of plants, despite to the high Zn accumulation in shoots. The growth, biomass accumulation, photosynthesis rate, and pigment amount were inhibited at Zn concentrations of 100 and 150 mg kg−1 in substrate. A slight increase in malondialdehyde (MDA) was also observed at zinc concentrations (100 and 150 mg kg−1) without changes in membrane permeability, which is partly connectedtoan increase in the proline content. The results suggested that white mustard tolerates Zn excess impact. S. alba is able to grow on Zn-contaminated substrates along with significant Zn accumulation in shoots, which supports its high potential for phytoremediation of Zn-polluted agricultural soils. It is also possible to propose the following recycling of white mustard plants for Zn fortification feedstuff.

Выявлено также усиление активности ферментов антиоксидантной защиты, направленное на сохранение окислительно-восстановительного баланса клеток [Казнина и др., 2016;Batova et al, 2021].…”
