Enhancing protein stability in transgenic plants

摘要

The present invention provides compositions and methods for enhancing protein stability in transgenic plants. The compositions are nucleic acid constructs which encode fusion proteins, fusion proteins, transgenic plant cells and transgenic plants. A fusion protein in accordance with the present invention comprises a protein of interest and a UBA1 or UBA2 domain of an Arabidopsis RAD23 protein. The methods use the nucleic acid constructs to produce fusion proteins in transgenic plant cells or transgenic plants. The fusion proteins have greater stability than the protein of interest and have the same function as the proteins of interest.
