Genome sequencing

Definition

Genome sequencing is the process of determining the complete DNA sequence of an organism's genome, which includes all of its genes and non-coding regions. This technique allows scientists to analyze genetic information, identify variations, and understand the genetic basis of traits, diseases, and evolutionary relationships in plants. By generating comprehensive genetic maps, researchers can utilize this data for plant breeding, conservation, and biotechnological applications.
