Nanomaterials Induced Genotoxicity in Plant: Methods and Strategies
No full textIn recent years, plant-nanomaterial interactions have been studied, highlighting their effects
at physiological and molecular levels. Transcriptomics and proteomics studies have shown
pathways and targets of nanomaterial exposure and plant response, with particular regard to abiotic
stress and oxidative stress. Only little information has been reported on engineered nanomaterial
(ENMs) interactions with plant genetic material, both at a genomic and organellar DNAs level.
Plants can be useful experimental material, considering they both contain chloroplast and mitochondrial
DNAs and several plant genomes have been completely sequenced (e.g., Arabidopsis thaliana,
Solanum lycoperiscum, Allium cepa, Zea mays, etc.). In this mini review, the methods and the evidence
reported in the present literature concerning the level of genotoxicity induced by ENMs exposure
have been considered. Consolidated and potential strategies, which can be applied to assess the
nanomaterial genotoxicity in plants, are reviewed
