“…2000). Transportery niskiego powinowactwa zlokalizowane są w korzeniach oraz liściach i zaangażowane są w transport jonów z roztworu glebowego do korzenia, jak również uczestniczą w międzykomórkowym transporcie z apoplastu do symplastu (Handa 2016). Badania na roślinach z nadekspresją genów kodujących transportery wysokiego powinowactwa lub niskiego powinowactwa, wykazały wzrost akumulacji selenianu u mutantów z nadekspresją genów kodujących transportery wysokiego powinowactwa w porównaniu z roślinami dzikimi.…”

Plant organisms are exposed to various biotic and abiotic stress factors, which cause oxidative stress consisting in the imbalance between the formation and removal of reactive oxygen species, causing damage to cell components. It has been observed that the accumulation of trace elements such as arsenic, cadmium, nickel, zinc and selenium is one of the plants defence strategies against phytophages and it is termed as Elemental Defence Hypothesis. Included in the trace elements, selenium is taken up from the soil by plants and included in their metabolism along sulphur transport and transformation pathways. This element in low concentration supports the resistance of plants to various stress factors by affecting the elements of the antioxidant system. Selenium contained in plants can also act on as a deterrent to phytophages or feeding them toxins and disrupting their development cycle.

“…However, Se can be toxic at relatively high levels, and there is a narrow threshold between Se sufficiency and excess Se compared to other micronutrients, resulting in global concerns regarding Se toxicity [ 23 , 24 ]. Given the similarities between Se and S, their biochemical properties are closely related [ 25 ]. Within plant roots, Se is transported across the cell membrane in the form of selenates via sulfate penetrases and channels or as selenites through phosphate transport mechanisms and other ion channels [ 26 ].…”

Zinc (Zn)- and iron (Fe)-regulating transport-like proteins (ZIPs) are a class of proteins crucial for metal uptake and transport in plants, particularly for Zn and Fe absorption and distribution. These proteins ensure the balance of trace elements essential for plant growth, development, and metabolic activities. However, the role of the rice (Oryza sativa) OsZIP gene family in manganese (Mn) and selenium (Se) transport remains underexplored. This research conducted an all-sided analysis of the rice OsZIPs and identified 16 OsZIP sequences. Phylogenetic analysis categorized the OsZIPs predominantly within the three subfamilies. The expression levels of OsZIPs in rice root and leaf subjected to Mn and Se toxicity stress were examined through quantitative real-time PCR (qRT–PCR). The findings revealed significant differential expression of many OsZIPs under these conditions, indicating a potential regulating effect in the response of rice to Mn and Se toxicity. This work lays a foundation for further functional studies of OsZIPs, enhancing our understanding of the response mechanisms of rice to Mn and Se toxicity and their roles in growth, development, and environmental adaptation.

“…1 The consumption and utilization of oxygen in various physiological processes turn down to the generation of ROS, including hydrogen peroxide (H 2 O 2 ), superoxide (O 2 ), and hydroxyl radical ( • OH). 2 All ROSs can be harmful and toxic to organisms at high concentrations. 3 Overproduction of H 2 O 2 is a deleterious process, which can be very damaging because it leads to various diseases such as cardiovascular disease, Alzheimer's disease, and cancer.…”

In this study, an innovative strategy was proposed for the electrocatalytical reduction and enzymatic biosensing of hydrogen peroxide (H 2 O 2 ) using chronoamperometry technique. For the first time, immobilization of horseradish peroxidase (HRP) in polydopamine-modified magnetic nanoparticles (PDA-MNPs) was successfully performed. Also, poly(L-arginine/toluidine blue) film-modified glassy carbon electrode was constructed through co-electropolymerization of L-arginine and toluidine blue on the surface of GCE using cyclic voltammetry technique. The engineered hybrid thin film provides strong functionalities for efficient grafting of PDA-MNPs which, in turn, enable the covalent immobilization of HRP. The proposed biosensor was used for the detection of H 2 O 2 in the range of 0.5-30 μM with a low limit of quantification 0.23 μM. It also was successfully applied for the investigation of hydrogen peroxide in human plasma samples.
