1 Obvious increase in grain protein, prolamine (zein) and glutelin content of high-oil corn at different levels of nitrogen application was observed.

2 In other words, the content of 13kDa prolamine amount subunit is different in the different species.

3 The total protein content of the grain, the prolamine content and the sedimentation value all negatively correlated with TOM respectively.

4 The technique of each step was determined through experiments and the yield of corn prolamine in the experimental condition was 80 percent.

5 The results show that there is obvious polymorphism in rice prolamine content among the lines studied.

6 By this means, we identified some of indica and japonica rice containing higher glutelin content and lower prolamine content.

7 In endosperms, globulin had the most amount of quantity, then was glutelin, albumin was in the third place, and prolamine was the lowest.
