Key Points

To engineer the plasmid pT181 antisense RNA-mediated transcription attenuation system to independently regulate multiple targets, execute genetic logic, and directly propagate signals without protein intermediaries.
Engineered sequence variants of the plasmid pT181 antisense RNA system to alter RNA-RNA interaction specificity for independent multi-target control.
Assembled attenuator variants in tandem arrays and cascaded architectures to evaluate genetic logic processing and direct RNA-to-RNA signal propagation.
Generated orthogonal pT181 variants capable of independently regulating multiple genetic targets simultaneously within the same cell.
Demonstrated functional tandem configurations that integrate multiple regulatory inputs to perform synthetic genetic logic operations.
Constructed a direct RNA-mediated transcriptional cascade, eliminating the need for intermediate proteins to transmit regulatory signals.
