Gel Electrophoresis of Proteins for the Identification of Crop Varieties

With the development of the international trade and agricultural science and technology, especially after the execution of the rules on protection of new plant varieties, considerable emphasis has been placed on variety identification. Many evidences have suggested that gel electrophoresis have great influence on this area. This paper reviewed study status of various gel electrophoresis, including development of the methods, comparison of these techniques, influence factors, practical applications, achievements obtained and aspects in the future study. With the wider range on protection of new plant varieties in China, electrophoresis will play a more important role in variety identification.
