An improved method for preparation of protoplasts of Arabidopsis thaliana cells grown in suspension culture is presented. This method is fast, reliable and can be used for the production of virtually an unlimited number of protoplasts at any time. These protoplasts can be transformed efficiently with RNA from turnip yellow mosaic tymovirus (TYMV) by polyethyleneglycol-mediated transfection. The simple transfection procedure has been optimized at various steps. Replication of TYMV can be monitored routinely by detection of the coat protein in as few as 2 x 10(4) infected protoplasts.
