Title: Hanping Guan: Innovator in Agricultural Biotechnology
Introduction
Hanping Guan is a prominent inventor based in Ames, Iowa, known for his contributions to agricultural biotechnology. He holds a total of 5 patents that focus on enhancing the nutritional qualities of crops and developing innovative starch production methods. His work has significant implications for food science and agricultural practices.
Latest Patents
One of Hanping Guan's latest patents is for transgenic corn having enhanced nutritional qualities. This invention provides transgenic corn seed that expresses a gene encoding a double mutant of the glgC gene in endosperm plastids. The mutant protein features a proline to aspartic acid substitution at amino acid 295 and a glutamic acid to lysine substitution at amino acid 296. The transgenic corn seed is characterized by enhanced levels of several amino acids and oil compared to isogenic corn seed that does not express the transgene. However, the amount of starch in the transgenic corn seed is decreased or unchanged when compared to the isogenic control corn seed.
Another significant patent involves plant-like starches and the method of making them in hosts. This invention relates to hosts containing constructs with genes from the starch pathway, particularly bacterial hosts that form plant-like starches. Additionally, it encompasses plant hosts that have genes from the starch pathway, along with the starches produced by these hosts.
