Stone formation in Prunus--How are stones formed in Prunus and is it possible to manipulate gene expression to prevent the stone hardening?
We have planted several different plum trees (Prunus domestica, prune plums) that came from Luther Burbank’s breeding program from 1900, that have almost no stone. We are using these as breeding material to improve as well as experimental material to determine what the mutation is that prevents stone tissue from being formed.
In addition we have identified genes involved in the process and have genetically engineered plum trees to test if by manipulating those genes there is an effect on the stone formation. These could then be targets for selective breeding.
