Gayle Volk, a plant physiologist at the U.S. Department of Agriculture describes citrus as "fascinating" due to many of the crops processed through hybridization. Citruses have a huge genetic diversity, unlike any other fruit. This recent research has opened up the exploration of the citruses' evolutionary journey. They analyze the genomes of numerous citruses and then study the uncovered insights into the origin of these fruits. Recent hypotheses have stated the origin of citruses was from the Himalayas to northeastern Australia, but after further study, they figured out they originated from south-central China.
Understanding the genetic origins of citrus has significant implications for their preservation and conservation during environmental challenges such as pests and diseases. Gayle Volk emphasizes the importance of refining the genetic origins for effective conservation. Overall, this genetic study offers us a good glimpse into the complex history of citrus fruits. It shows not just their evolutionary journey but also the critical role genetics play in shaping their flavors and looks.
