Title: Judy Callis: Innovator in Plant Biotechnology
Introduction
Judy Callis is a prominent inventor based in Davis, CA (US). She has made significant contributions to the field of plant biotechnology, particularly through her innovative patents. With a total of 2 patents, her work focuses on enhancing protein production in plants and targeting specific proteins for degradation.
Latest Patents
One of her latest patents is titled "Sequences from auxin-induced gene products targeting fusion proteins for degradation." This invention provides isolated nucleic acid molecules that comprise a polynucleotide sequence encoding a primary auxin response protein degradation signal linked to a heterologous eukaryotic polynucleotide sequence encoding a target polypeptide. Additionally, it includes transgenic plants that comprise an expression cassette of the polynucleotides of the invention. The invention further outlines methods for targeting a recombinantly expressed target polypeptide in a plant for degradation.
Another notable patent is the "Ubiquitin fusion protein system for protein production in plants." This patent describes the use of a gene for plant ubiquitin, isolated from Arabidopsis thaliana, in a plant expression vector to produce a ubiquitin-protein fusion. Natural factors in the plant cleave such a fusion protein to release ubiquitin and the desired protein. This method has been found to yield higher protein expression levels compared to the expression of the protein alone.
