Magnesium-Doped Carbon Quantum Dot Nanomaterials Alleviate Salt Stress in Rice by Scavenging Reactive Oxygen Species to Increase Photosynthesis

ACS Nano, Journal Year: 2024, Volume and Issue: 18(45), P. 31188 - 31203

Published: Nov. 1, 2024

Salt stress has strongly impacted the long-term growth of eco-friendly farming worldwide. By targeting oxidative induced by salt, utilization biomass-derived carbon dots (CDs) that possess high-efficiency antioxidant properties, are nontoxic, and have excellent biocompatibility represents a viable effective approach for enhancing salt tolerance plants. In this study, we blended magnesium oxide nanoparticles with sources derived from durian shells to construct Mg-doped (Mg-CDs) through hydrothermal reaction. We demonstrated foliar application 150 μg/mL Mg-CDs rice plants after treatment 100 mM effectively increased plant height (9.52%), fresh weight (22.41%), dry (33.33%), K+ content (21.46%), chlorophyll (36.21%), carotenoid (16.21%); decreased malondialdehyde (MDA) (9.43%), Na+ (25.75%), H2O2 (17.50%), O2•– contents (37.99%); promoted photosynthetic system activity. Transcriptome analysis revealed Mg-CD pretreatment triggered transcriptional reprogramming in seedlings. The enrichment Kyoto Encyclopedia Genes Genomes pathways based on trend groups gene expression patterns Profile 8 15 indicated priming activated signaling- defense-related pathways, such as metabolic biosynthesis secondary metabolites, photosynthesis pathways. These activations subsequently prompted genes related mitogen-activated protein kinase signaling pathway, hormone signal transduction, response, system. This study use potential strategy increase tolerance, creating possibility regulation crop salinity offering valuable advancements sustainable agriculture.

Root-Applied Cerium Oxide Nanoparticles and Their Specific Effects on Plants: A Review

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(7), P. 4018 - 4018

Published: April 4, 2024

With the pronounced increase in nanotechnology, it is likely that biological systems will be exposed to excess nanoparticles (NPs). Cerium oxide (CeO2 NPs) are among most abundantly produced nanomaterials world. Their widespread use raises fundamental questions related accumulation environment and further interactions with living organisms, especially plants. NPs present either soil or soilless environments absorbed by plant root transported aboveground parts. After entering cytoplasm, interact chloroplast, nucleus, other structures responsible for metabolic processes at cellular level. In recent years, several studies have shown impact of nanoceria on growth processes. Research performed different plants has a dual role CeO2 NPs. The observed effects can positive negative strongly depend species, characterization, concentrations This review describes root-applied growth, photosynthesis, metal homeostasis, parameters induced oxidative stress.

Journal of Soils and Sediments, Journal Year: 2024, Volume and Issue: 24(12), P. 3814 - 3823

Published: Aug. 2, 2024

Abstract Purpose Rare Earth Elements (REEs) are becoming more present in our everyday life. With this work, we aimed to study and compare the toxic responses of REEs lanthanum (La), cerium (Ce), neodymium (Nd), gadolinium (Gd) macrophyte Myriophyllum aquaticum . The scope was evaluate if these elements trigger a response on photosynthetic system (PSII), which causes inhibition growth rate plant. Methods We measured fluorescence yield by pulse-amplitude-modulated chlorophyll fluorometer (PAM) enabled simultaneous high-resolution measurements whorls daily for whole duration test (10 days) fresh weight change (FWC) at end test. Results Our findings suggest that La significantly decreased FWC highest concentration (500 mg kg −1 ) but did not cause any significant effects yield.
