It has been known for many years that the scent of a rose fades over a short period of time as it is mentioned in the article, How a Rose Blooms: Its Genome Reveals the Traits for Scent and Color. Generations of breeding in order to obtain longer blooms and rose petals have stultified the beautiful smell that has perfumed many gardens around the world. Due to such a thing, researchers from France have investigated which specific gene causes the rose to have a sweet odor and have explored the genome in order to enhance the distinctive scent. To successfully obtain the desired result, breeders made thousands of hybrid offspring. This was done in order to be able to be able to identify the combination of the traits that they seek. Next, they selected the offspring that consist of the desired trait. Also, they are aware that this process might take up to 10 long years and will take up a large amount of land. Dr. Mockler, who is a part of this experiment stated, “the big challenge is you need to know what to edit. You can’t just randomly start editing. You have to know what to target. The only way you know that is to have a genome sequence.” He believed that editing the genes of roses is something that is realistic and possible due to the fact that there’s a good road map of the genes presented.
