Abstract

Global agricultural productivity and food security are facing severe challenges from abiotic stresses, necessitating sustainable agricultural innovations to address this issue. Nanotechnology, as a pioneering approach, holds great promise for improving crop yields, with carbon dots (CDs) emerging as a particularly attractive solution due to their ease of synthesis, excellent biocompatibility, and low toxicity. This review summarizes the synthetic strategies of CDs, their structural characteristics, potential properties, and toxicity evaluation, as well as their capacity to enhance crop productivity by improving photosynthesis, nutrient uptake efficiency, and antioxidant defense systems. Additionally, we discuss the application of CDs in alleviating abiotic stresses that affect plants, such as drought, salinity, heavy metal toxicity, and extreme temperatures. We also discuss the physiological, biochemical, and molecular mechanisms through which CDs enhance plant tolerance to these stresses. The versatility and effectiveness of CDs in sustainable agriculture position them as promising candidates for future agricultural practices aimed at mitigating the impacts of abiotic stress.

碳点介导的植物对非生物胁迫的适应性反应

全球农业生产率和粮食安全正面临着非生物胁迫的严峻挑战，需要可持续的农业创新来解决这一问题。纳米技术作为一种开创性的方法，在提高作物产量方面大有可为，其中碳点（CD）因其易于合成、生物相容性好和毒性低，成为一种特别有吸引力的解决方案。本综述概述了碳点的合成策略、结构特征、潜在特性和毒性评估，以及它们通过改善光合作用、养分吸收效率和抗氧化防御系统来提高作物产量的能力。此外，我们还讨论了 CD 在缓解干旱、盐碱、重金属毒性和极端温度等影响植物的非生物胁迫方面的应用。我们还讨论了 CD 增强植物对这些胁迫的耐受性的生理、生化和分子机制。CDs在可持续农业中的多功能性和有效性使其成为未来农业实践中旨在减轻非生物胁迫影响的有前途的候选物质。

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
