Nanomaterials and nanotechnology have garnered significant attention in the realm of agricultural production. Carbon dots (CDs), as a class nanomaterials, play crucial role field plant growth due to their excellent properties. This review aims summarize recent achievements on CDs, focusing methods preparation applications plants systems. The effects CDs seed germination, growth, photosynthesis, nutritional quality, stress resistance were studied. It has been demonstrated that can promote germination well improve photosynthetic efficiency, ultimately leading increase yield. quality treated with was significantly improved. Specifically, levels essential mineral elements, vitamins, amino acids, other constituents are beneficial human health increased notably. Additionally, show positive augmenting against environmental stresses, such drought conditions, heavy metal toxicity, high salinity. Finally, prospects challenges application systems also discussed, which provide scientific basis for future

Sunlight‐sensitive carbon dots for plant immunity priming and pathogen defence

Plant Biotechnology Journal, Journal Year: 2025, Volume and Issue: unknown

Published: March 16, 2025

Summary Global food production faces persistent threats from environmental challenges and pathogenic attacks, leading to significant yield losses. Conventional strategies combat pathogens, such as fungicides disease‐resistant breeding, are limited by contamination emergence of pathogen resistance. Herein, we engineered sunlight‐sensitive biodegradable carbon dots (CDs) capable generating reactive oxygen species (ROS), offering a novel sustainable approach for plant protection. Our study demonstrates that CDs function dual‐purpose materials: priming immune responses serving broad‐spectrum antifungal agents. Foliar application generated ROS under light, the could damage cell wall trigger wall‐mediated immunity. Immune activation enhanced resistance against pathogens without compromising photosynthetic efficiency or yield. Specifically, spray treatment with at 240 mg/L (2 mL per plant) reduced incidence grey mould in N. benthamiana tomato leaves 44% 12%, respectively, late blight 31%. Moreover, (480 mg/L, 1 mL) combined continuous sunlight irradiation (simulated xenon lamp, 9.4 × 10 5 lux) showed activity. The inhibition ratios mycelium growth were 66.5% P. capsici , 8% S. sclerotiorum 100% B. cinerea respectively. Mechanistic studies revealed effectively inhibited damaging hyphae spore structures, thereby disrupting propagation vitality pathogens. These findings suggest offer promising, eco‐friendly strategy crop protection, potential practical agricultural applications maintain yields minimize impact.
