Is there a bacteria/animal/fungi equivalent of rootstock that selective breeding has used?
I know we study some long lived germlines of E. coli for example. And how about mushroom farms?
I see. One of the two common GMO types is BT, which is a bacteria that produces a protein which is an insecticide. It is widely used in organic farming, especially for caterpillar control. I use it on my edible plants in late summer when we get a lot of caterpillars. In GMO varieties, the BT gene that produces the protein is grafted on to a popular cultivar so they produce their own insecticide.
