Protoplasts were generated from 3-day-old Arabidopsis Col-0 dark-grown cell suspension culture, and the transformations were carried out in small scale in 96 well plates with round-bottom (Roth) as previously described [30 (link)] using a Liquidator96 Manual Pipetting system (Steinbrenner GmbH, Germany).
