Variation of Seed Protein in Wheat Grain after Introducing DNA from Pea Flower

Abstract

Abstract: The seed proteins of variant lines of wheat into which exogenous DAN was directly introduced were analyzed via SDS-PAGE.The result showed that the seed protein components remarkbly changed:in Xiaoyan6 and Suporear wheat varieties the new proteins such as 47KD，71KD and 90KD，85KD appeared，and the protein contents also increased about 22% and 31% compared with that of the control.On the other hand，in Chinese Spring wheat protein components 92KD，82KD disappeared，and the protein contents decreased slightly(6%).These variations can be stably passed onto the progenies.It is，therefore，suggected that the technology of direct exogenous gene transfer to plants may be a new approach for breeding and improving nutrient quality in wheat.
