Actually that article got me interested in thinking I could actually do it.
I remember hearing about if you take an adult plant, manipulate some cells, some replicate and others don't. If i was working with something as small as a leaf (they are about 2x this size ------> 0 ) If i could continually introduce the new cells, do you think they would eventually take?
Mind you, in essence, the tissue culture is just a more elaborate way I would be propagating the plant. (The general way is just an egg carton with 12 branches/leaves of the plant, and a growing medium).
So the question is how I 'inject' (to use the term loosely) another plant/organism/chemical etc to get it to grow faster, and carry that trait to the next generation....?
