Using mobile DNA to increase grapevine diversity

Abstract

Mobile DNA sequences harbour the potential to generate new genetic variations, through mutations caused by their occasional rearrangement of the genome. By exposing grapevine cells to stress conditions such as temperature shock and microbial populations, we have demonstrated that the rate at which this change occurs can be artificially modulated. By increasing the activity of mobile elements, we can effectively accelerate the natural genetic diversification of a plant population. This provides a mean to access genetic and physical traits not currently extant in the crop species.
