Plant biologists at the University of California, Davis, have discovered a way to make crop plants replicate through seeds as clones. The discovery …. could make it easier to propagate high-yielding …. crops and make them available to the world’s farmers.
The ability to produce a clone …. of a plant from its seeds would be a major breakthrough for world agriculture. Instead of purchasing expensive hybrid seeds each year …. farmers could replant seeds from their own hybrid plants and derive the benefits of high yields year after year.
The researchers first used gene editing to prevent the plants from going through meiosis, a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. Instead, the egg cells form by mitosis, inheriting a full set of chromosomes from the mother.
Then they caused these egg cells to express BBM1, which they would not normally do without fertilization …. The approach should work in …. other crop plants as well ….
