Fig 3. Designed unidirectional genetic switches composed of two sets of synthesized plasmids.

(a) and (b) Plasmid sets for S1 strategy in mammalian and plant models, respectively. (c) Plasmid sets for S2 strategy applied for plant models. Here, the promoter sequence, not the gfp gene, is under the control of integrase-mediated inversion and activation. Figure adaptation from Gomide et. al., 2020 [16].
