In a recent issue of Trends in Plant Science, Caius Rommens et al.[1] provided a valuable overview of intragenic modification in the context of other plant breeding approaches. These authors defined an intragenic plant as a genetically modified plant that only contains genetic elements from within the sexual compatibility group. Intragenesis, an innovative gene technology breeding method, creates new genes with desired traits by isolating functional genetic elements such as promoters, coding parts or terminators of existing genes, rearranging them in vitro, and inserting this new ‘intragenic’DNA combination back into the plant. According to Rommens et al.[1], this approach mimics traditional plant breeding, with the added advantage that the sequence of the inserted DNA is far better known than is DNA used in traditional plant-breeding technologies such as introgression breeding. Therefore, they state that …
