genomic-analysis
Genomic analysis is the systematic examination of an organism's complete DNA sequence to identify genes and understand their biological functions. In plant science, genomic analysis is invaluable for uncovering the genetic basis of critical agronomic traits—such as crop yield, disease resistance, and environmental stress tolerance. This knowledge enables plant scientists to develop improved crop varieties through targeted breeding strategies, ultimately accelerating agricultural innovation and sustainability.
