1) Crop genomics uses high-throughput DNA sequencing and bioinformatics to assemble and analyze the entire genome of a plant in order to understand its complex biological systems. 2) Genomics has been successfully applied to identify genes associated with drought tolerance, disease resistance, and heavy metal toxicity to help combat climate change and address food security issues. 3) There is an opportunity to direct more emphasis on using genomics to enhance the nutritional value of crops during breeding programs in order to improve nutritional security, especially in developing nations.
