One alternative plant transformation tek I am so excited to try is the carbide whisker method. It uses thin silicon carbide fibers (nano-needles) to poke the crap out of plant tissue. Just adsorb DNA onto whiskers, add plant bits, and vortex for 1min. Obvs do not breathe in dust; respirator a MUST.
