Programmable nanocarriers for precision plant engineering: converging nanotechnology, CRISPR, and next-generation breeding.
Review in Frontiers in plant science, 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
The convergence of nanotechnology and genome editing in plant sciences is redefining modern precision breeding through efficient, transgene free, tissue culture independent pathways for genetic improvement in crops. Conventional breeding and transgenic tools are limited to genotype dependency, inefficient gene delivery, unpredictable transgene insertions, thereby restricting their application in elite germplasm. Nanoparticles-mediated gene delivery systems have revolutionized the genetic transformation in plants through targeted and transgene free delivery of CRISPR/Cas ribonucleoproteins (RNPs), DNA, and RNA into plant cells, while minimizing genome interference. Nanocarriers are the engineered delivery systems wherein the material component is a nanoparticle. DNA-free delivery refers to the absence of exogenous DNA during editing, whereas transgene free plants are those that do not retain integrated foreign DNA after regeneration. Firstly, this review summarizes current progress in designing nanocarriers, including lipid, polymeric, mesoporous silica nanoparticles, carbon-based nanoparticles, layered double hydroxides, and DNA-based nanoparticles; harnessing the function of their physicochemical traits in modulating plant cellular uptake, cargo stability, controlled delivery, and tissue specific targeting in plants. Secondly, the broad-spectrum roles of nano particles in genome editing, crop protection via RNA interference, organelle-targeted modifications are discussed, stressing transgene free approaches to mitigate somaclonal variation and regulatory concerns to foster public acceptance. The integration of nano-mediated delivery with speed breeding, meristem transformation, multiplexed editing in elite germplasm is proposed as an approach for prompt trait stacking and validation. Thirdly, the collaborative roles of experts in the field of nanotechnology, plant breeding, plant physiology, and agronomy are mentioned for mitigating multifaceted climatic effects and glitches. Moreover, current challenges including nanotoxicity, scalability and field translation, regulatory concerns, and public perception are also discussed. While nanocarrier mediated delivery shows strong potential for improving plant genome engineering, current evidence is largely confined to controlled experimental systems, and significant challenges remain before routine integration into breeding pipelines becomes feasible.
