The Gene Gun has most certainly become the weapon of choice for folks trying
to transform maize and barley (wheat too?), but it is hardly a "one kingdom
tool". There are reports of transformation coming in from all five kingdoms.
The following references might be usefull to those who want to know what the
gunslingers of today are up to:

These refs are more to demonstrate the breadth of the technique than anything
As to what PLANT BIOLOGISTS are doing with the gun... I'd say: just about
BTW: I think making plants more resistant to herbicides ranks right up there
with building nuclear power plants on KNOWN faults. ( steps off soapbox )
