Noncoding RNAs as tools for advancing translational biology in plants

Abstract

Noncoding RNAs (ncRNAs), once considered the "dark matter" of the genome, have emerged as critical regulators of gene expression in plants. Research initially focused on model organisms has laid the groundwork for harnessing the potential of ncRNAs in agriculture, particularly for crop protection, improvement, and modulation. This review explores the role of long and small ncRNAs in plant biology, highlighting their application as powerful tools in agricultural biotechnology. We examine the latest strategies for ncRNA expression and delivery in crops, including transgenic and nontransgenic approaches, as well as emerging technologies that enable precise and efficient modulation of gene activity in plants and pathogens. Additionally, we provide a comprehensive overview of the current state-of-the-art in the regulation of RNA-based products, addressing the challenges and opportunities for integrating these innovations into sustainable agricultural practices. As the regulatory landscape evolves, understanding the safety, efficacy, and environmental impact of ncRNA-based technologies will be crucial for their successful deployment. By leveraging the advances in plant science research, long and small ncRNAs hold promise for designing highly specific tools to boost crop productivity while preserving genetic diversity, contributing to global food security and sustainable agriculture.
