The % of leaf discs giving at least 1 regenerant after 8 weeks on kanamycin is shown in the second column. The % of PCR-positive shoots containing the transgene are shown in the third column. The % transgenosis (fourth column) indicates the % of leaf disks giving at least 1 PCR-positive regenerant.
