Abstract

Methods of unencrypting trait encrypted gene sequences to provide unencrypted RNAs or polypeptides. The invention also relates to methods of encrypting traits including splitting genes between two parental organisms or between a host organism and a vector. The gene sequences are unencrypted when the two parental organisms are mated or when the vector infects the host organism by trans-splicing either the split RNAs or split polypeptides upon expression of the split gene sequences. The invention also includes methods of providing multiple levels of trait encryption and reliable methods of producing hybrid organisms. Additional methods include those related to unencrypting engineered genetic elements to provide polypeptide functions and those directed at recombining non-overlapping gene sequences. The invention also includes integrated systems and various compositions related to the disclosed methods.
