In the current work, foliar application of selenium nanomaterials (Se0 NMs) suppressed sheath blight in rice (Oryza sativa). The beneficial effects were nanoscale specific and concentration dependent. Specifically, amendment 5 mg/L Se0 NMs decreased disease severity by 68.8% Rhizoctonia solani-infected rice; this level control was 1.57- 2.20-fold greater than that Se ions with equivalent mass a commercially available pesticide (Thifluzamide). Mechanistically, (1) controlled release ability enabled wider safe range bioavailability to NMs, (2) transcriptomic metabolomic analyses demonstrated simultaneously promoted salicylic acid- jasmonic-acid-dependent acquired resistance pathways, antioxidative system, flavonoid biosynthesis. Additionally, improved yield 31.1%, increased nutritional quality 6.4–7.2%, enhanced organic content 44.8%, arsenic cadmium contents 38.7 42.1%, respectively, grains as compared infected controls. Human simulated gastrointestinal tract model results showed bioaccessibility 22.0% As Cd 20.3 13.4%, respectively. These findings demonstrate can serve an effective sustainable strategy increase food security.

Accumulation of cadmium (Cd) ions in soil is an increasingly acute ecological problem agriculture production. Selenium nanoparticles (SeNPs) can mediate Cd tolerance plants; however, the underlying mechanisms remain unclear. Herein, we show that foliar application SeNPs improved adaptive capacity tomato plants to decrease Cd-induced damage. induced more roots but not shoots despite greater accumulation selenium and sulfur both tissues high selenate influx. Additionally, significantly increased thiol compounds, including glutathione, cysteine, phytochelatins, contributing enhanced detoxification. Importantly, expression sulfate transporters 1:3, S-adenosylmethionine 1 polyamine transporter 3. Then, experiments with mutants these genes showed SeNP-reduced stress largely relies on levels shoot-to-root transport selenium/sulfur polyamines. These findings highlight potential improve crop production phytoremediation heavy metal-contaminated soils.

Salinity stress is a prominent environmental factor that presents obstacles to the growth and development of plants. When soil contains high salt concentrations, roots face difficulties in absorbing water, resulting water deficits within plant tissues. Consequently, plants may experience inhibited growth, decreased development, decline biomass accumulation.

Bamboo is nutritionally significant across the world because shoots are high in calories and nutritional fiber but low cholesterol. However, recent research has shown that bamboo also contain a substantial quantity of heavy metals, including arsenic (As).
