Certain plant cell lines can be genetically unstable. Thus they would
be quite prone to loosing the valuable gene that they would contain.
An example of such unstable types of cells is Alfalfa suspension
cells, which frequently loose chromosomes and double others, if they
are kept growing in culture for a long time.

Don't be sorry asking questions is the only way you'll learn. Oh, by
the way plant scientists are generally refered to as Botanists, just
thought you'd like to know. :)
