Abstract
We have investigated factors influencing polyethylene glycol mediated DNA uptake and beta-glucuronidase expression in pea (Pisum sativum L.) protoplasts. It was found that for optimal beta-glucuronidase express ion the molecular weight and concentration of polyethylene glycol shou ld be 4000 and 20%, respectively. The amount of plasmid DNA should be 25 mug per 5 x 10(5) protoplasts in each treatment, and the concentrat ion of Mg2+ in the transformation buffer should be 15 mM. The optimize d protocol was applicable to all four pea cultivars tested.
