2135643 9323532 PCTABS00028 The invention features a responsive RNA molecule which encodes, in one or more protein-coding regions, a polypeptide, and which includes a regulatory domain, a substrate region, and a ribosome recognition sequence. This responsive RNA molecule has an inhibitor region in the regulatory domain, which regulatory domain is complementary to both a substrate region of the responsive RNA molecule and to an anti-inhibitor region of a signal nucleic acid such that, in the absence of the signal nucleic acid, the inhibitor and substrate regions form a base-paired domain the formation of which reduces the level of translation of one of the protein-coding regions in the responsive RNA molecule compared to the level of translation of that one protein-coding region observed in the presence of the signal nucleic acid. The anti-inhibitor region of the signal nucleic acid is complementary in sequence to the inhibitor region of the responsive RNA molecule such that when the anti-inhibitor region is base-paired with the inhibitor region, translation of one protein-coding region of the responsive RNA is increased compared to the level of translation of that protein-coding region observed in the absence of the signal nucleic acid. The signal nucleic acid comprises part of the nucleic acid of a plant cell infecting organism.
