Abstract:
1. A method for selectively controlling the transcription of a gene of interest in a plant, comprising: i) producing a first plant comprising a first genetic construct, said first genetic construct comprising a first regulatory region operatively linked to a gene of interest and one, or more than one, ROS operator sequence capable of controlling the activity of said first regulatory region, the ROS operator sequence comprising a sequence selected from the group consisting of SEQ ID NO: 20, an inverted repeat of SEQ ID NO: 20, and a combination thereof; ii) producing a second plant comprising a second genetic construct, said second genetic construct comprising a second regulatory region in operative association with a nucleic acid molecule, encoding a ROS repressor selected from the group consisting of iii) crossing said first plant and said second plant to obtain progeny, said progeny comprising both said first genetic construct and said second genetic construct, and characterized in that the expression of said second genetic construct represses expression of said first genetic construct.
