“…6 Selenium-biofortified rice displays a vast diversity of biofunctions and nutritive value. 6 Some selenium-enriched ingredients, especially selenopeptides and selenium-enriched fermented products (i.e., selenoproteins and selenium-containing nanoparticles) in microorganisms, present low toxicity and high bioactivities. In recent years, selenopeptides have emerged as both selenium supplements and favorable sources of peptides.…”

Dietary deficiency of selenium is a global health hazard. Supplementation of organic selenopeptides via food crops is a relatively safe approach. Selenopeptides with heterogeneous selenium-encoded isotopes or a poorly fragmented peptide backbone remain unidentified in site-specific selenoproteomic analysis. Herein, we developed the Se-Pair Search, a UniProtKB-FASTA-independent peptide-matching strategy, exploiting the fragmentation patterns of shared peptide backbones in selenopeptides to optimize spectral interpretation, along with developing new selenosite assignment schemes (steps 1–3) to standardize selenium-localization data reporting for the selenoproteome community and thereby facilitating the discovery of unexpected selenopeptides. Using selenium-biofortified rice under cooking, fermentation, and high-temperature and high-pressure processing conditions as a pyrolysis-thermolysis dietary model, we probed the single-molecule-level kinetic evolution of the novel selenopeptide “KKSe(M)R” with qual-quantitative information on graph-theory-oriented localization calculations, abundance patterns, activation energy, and rate constants at a selenoproteome-wide scale. We ground-truth-annotated thirteen pyrolysis-thermolysis products and inferred four pyrolysis-thermolysis pathways to characterize the formation reactivity of the main intermediate variables of KKSe(M)R and constructed an advanced probe-type ultrasound technique prior to pyrolysis-thermolysis conditions for minimizing loss of KKSe(M)R during processing. Importantly, we reveal the unappreciated pyro-excitation diversion of KKSe(M)R at pyrolysis-thermolysis time and temperature matrices. These findings provide pioneering theoretical guidance for controlling dietary selenium supplementation within the safety thresholds.

“…However, the overapplication of Se fertilizers is associated with some environmental risks, such as the contamination of soil and water, toxicity to plants and animals, and bioaccumulation in the food chain ( Lemly, 1997 ; Gupta and Gupta, 2016 ; Hasanuzzaman et al., 2020 ). Therefore, changing the method of application and the form of Se fertilizer or simultaneously using other enhancers, such as an environmentally friendly microbial fertilizer, can improve the availability of this element in Se fertilizer ( Chen et al., 2020 ; Yang et al., 2021b ; Wang et al., 2022 ; Xian et al., 2022 ; Yuan et al., 2022 ). Plants primarily rely on their roots to absorb Se from the soil, and the roots can take up both inorganic Se (selenate [SeVI] and selenite [SeIV]) and organic Se [Se-amino acids, including selenocysteine (SeCys), selenomethionine (SeMet) and methylselenocysteine (MeSeCys)] ( Lima et al, 2018 ).…”

Although selenium (Se) is an essential trace element in humans, the intake of Se from food is still generally inadequate throughout the world. Inoculation with arbuscular mycorrhizal fungi (AMF) improves the uptake of Se in rice (Oryza sativa L.). However, the mechanism by which AMF improves the uptake of Se in rice at the transcriptome level is unknown. Only a few studies have evaluated the effects of uptake of other elements in rice under the combined effects of Se and AMF. In this study, Se combined with the AMF Funneliformis mosseae (Fm) increased the biomass and Se concentration of rice plants, altered the pattern of ionomics of the rice roots and shoots, and reduced the antagonistic uptake of Se with nickel, molybdenum, phosphorus, and copper compared with the treatment of Se alone, indicating that Fm can enhance the effect of fertilizers rich in Se. Furthermore, a weighted gene co-expression network analysis (WGCNA) showed that the hub genes in modules significantly associated with the genes that contained Se and were related to protein phosphorylation, protein serine/threonine kinase activity, membrane translocation, and metal ion binding, suggesting that the uptake of Se by the rice roots may be associated with these genes when Fm and Se act in concert. This study provides a reference for the further exploration of genes related to Se uptake in rice under Fm treatment.

Oxidative cracking of alkenes is a significant process in industry. In this work, it was found that catalyzed by Se/Fe via hybrid mechanisms, the carbon−carbon double bond in alkenes can break to produce carbonyls under mild conditions. Since O 2 can be used as a partial oxidant, the employed H 2 O 2 amount can be reduced (90 mol % vs 250 mol %) to avoid the peroxide residues, making the process even safer for operation.
