Multi-omics analysis reveals the crucial role of ligustrum lucidum carbon dots in promoting vegetable sweetpotato growth and enhancing soil health.
Article in BMC plant biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe development of sustainable agriculture requires the creation of efficient biostimulants that enhance crop yield and nutritional quality while minimizing environmental impact. Biomass-derived carbon dots, with their unique physicochemical properties and low toxicity, have emerged as promising candidates.
resultsThis study synthesized ligustrum lucidum carbon dots (LL-CDs) and evaluated their biological effects on vegetable sweetpotato over short-term periods (7 and 14 days). Foliar application of LL-CDs significantly promoted plant growth, biomass accumulation, photosynthetic efficiency, nutrient uptake, and antioxidant capacity. Transcriptomic and metabolomic analyses indicated that LL-CDs treatment synergistically upregulated photosynthesis-related pathways, including light capture, electron transport, and carbon fixation, and increased the accumulation of bioactive compounds. Additionally, LL-CDs improved soil nutrient availability and positively influenced the rhizosphere microbial community structure.
conclusionsThese preliminary results suggest that LL-CDs have the potential to be developed as agricultural nanomaterials, providing initial theoretical support and technical reference for the development of novel biostimulants.
