The present invention relates to compositions involving randomized in-frame fusion polynucleotides and their introduction into a host organism to identify desirable phenotypic changes. The present invention further relates to methods of generating these randomized in-frame fusion polynucleotides by introducing randomized in-frame fusion polynucleotides into an organism, selecting for organisms with new or altered phenotypes, re-isolating the randomized in-frame fusion polynucleotides from the selected organisms, re-assembling the constituent polynucleotides of the re-isolated randomized in-frame fusion polynucleotides into new collections of randomized in-frame fusion polynucleotides, and repeating the selection for organisms with new or altered phenotypes. |
