The feasibility of the equipment to measure Tg of amorphous powder is verified with a lot of experimentl results.The Tgs of some typical starches such as corn, pachyrhizus, buckwheat and pea in different water content are obtained by TDA. It is found that the water has plastic effect on starch and the Tg of starch decreases with the increase of water content. Through this study a quantitative expression is established to relate Tg and water content, and it is testified with experimental results for the sticky rice starch with different water content.

Different contribution of the genes to starch biosynthesisLeaves and developing endosperms of Q319, C7-2, q404, ZN-A and S8 were used to study the expression patterns of 44 genes participating in starch synthesis. We found that ZmGBSSⅠ、ZmSSⅢ、ZmSBEⅡb、ZmBT2-2、ZmSh2-2、ZmSh2-3、ZmBT1 were expressed exclusively in the metaphase and anaphase of developing endosperm, and the expression patterns of ZmSUS1、ZmSus1L、ZmSUS3、ZmSSⅠ、ZmSSⅡa、ZmSBEⅠ、ZmISO1、ZmPul were consistent with the process of starch synthesis in the endosperm, while ZmUGP3 and ZmSUT2 were highly-expressed in all samples, suggesting that these genes perhaps devoted to starch synthesis in endosperm.
