Exploring omics solutions to reduce micro/nanoplastic toxicity in plants: A comprehensive overview

Area of Science:

• Environmental Science
• Plant Biology
• Molecular Biology

Background:

• Plastic waste, including microplastics (MPs) and nanoplastics (NPs), poses a significant threat to agricultural ecosystems.
• Accumulation of MPs/NPs in soil alters physicochemical properties and disrupts microbial communities, impacting plant physiology and crop health.

Purpose of the Study:

• To elucidate the physiological and molecular mechanisms of plant responses to MP/NP stress using integrative omics.
• To identify key molecular targets for enhancing plant resilience against plastic pollution.

Main Methods:

• Genomics, transcriptomics, proteomics, metabolomics, and epigenomics were employed to analyze plant responses.
• High-throughput methodologies were utilized to identify genetic and metabolic alterations.

Main Results:

• Significant genetic and metabolic alterations were observed in plants exposed to MPs/NPs.
• Plants reconfigured metabolic pathways, activated antioxidant mechanisms, and modulated stress-responsive gene expression.
• Epigenetic modifications indicate adaptive responses to prolonged plastic exposure.

Conclusions:

• Integrative omics provide a comprehensive understanding of plant molecular interactions under MP/NP stress.
• Identified molecular targets can inform biotechnological and agronomic strategies to improve crop resilience.
• This research is crucial for developing sustainable solutions to mitigate plastic pollution in agriculture and ensure food security.
