Recent trends in nucleic acid research in plants for future food security.

The agricultural production system is facing unprecedented pressure of climate change, human population, pressure on renewable and non-renewable resources, and elevation in both biotic and abiotic stress factors. The recent development in nucleic acid based technologies have transformed research in plant sciences through deployment of powerful technologies for understanding complex biological mechanisms controlling climate resilience, nutrition and yield attributes in agriculturally important crops. This editorial documented the key results of 33 articles published in this special issue, covering application of various techniques to improve desirable attributes in agriculturally important crops. Furthermore, the published literature displayed the key findings emerging through the application of CRISPR-Cas based genome editing system, integration of multi-omics, application of machine learning, RNA-based regulations and chloroplast bioengineering with higher precision, efficiency, and reliability. The innovation in plant-microbe interaction, rhizosphere engineering has revealed novel avenues of research for improving the potential of resource use efficiency and sustainability. Altogether, the research published in this special issue may play a transformative role in advancing precision breeding, stress resilience and crop performance under ever-changing climatic conditions. However, there is a requirement for continuous interdisciplinary research, embracing innovation and international collaboration for utilization of full potential of cutting-edge technologies contributing significantly to achieving food security.
