Suppression of ag-TD Is Probably Mediated by Trans- Interaction between Two -DNA Insertions.(A) In situ analysis of AG expression in WT, ag-TD, and ag-TD*.(B) Conversion of ag-TD to ag-TD* correlates with the loss of kanamycin resistance.(C) Conversion of ag-TD to ag-TD* can be achieved by the introduction of a T-DNA fragment that expresses the NPT II gene. About 75% of the T1 plants with ag-TD genotype did not show the typical ag phenotypes.
