    This is the need for preserving as much of wild plants as possible. Because they can provide a gene pool, for adapting to sudden climatic change. It is like when the American chestnut tree was attacked by the Asian bark fungus, they were able to give the American chestnut tree the DNA of the Chinese chestnut tree, and create a new strain, which was resistant to the Asian bark fungus. American chestnut trees could be replanted in their former range. Hopefully, such a tactic can be used on addressing wheat rust too.
