Yes, absolutely.
To give a very simple example, if we were to think of a plant genome as being like a book or a novel, techniques of biotechnology—or techniques used to produce GMOs—are like inserting a brand new sentence into that book. Typically, it means inserting a gene from a non-sexually compatible species into a plant.
New techniques, like gene editing, have been in development just in the past five or six years. To go back to the book analogy, they would allow a change to a letter within that book, or perhaps changing a word within a sentence. They're very precise tools that can make very targeted changes to an existing plant gene.
