Abstract excerpt

Mutations in the DNA glycosylase/lyase ROS1 cause transcriptional silencing of the linked RD29A-LUC and 35S-NPTII transgenes in Arabidopsis. We report here that mutations in the Arabidopsis RPA2 locus release the silencing of 35S-NPTII but not RD29A-LUC in the ros1 mutant background. The rpa2 mutation also leads to enhanced expression of some transposons. Neither DNA methylation nor siRNAs at any of the...
