During growth phase the metabolic flux to glycerol synthesis was much large, and the carbon was mostly catabolized in TCA in the glycerol production process. With large flux through TCA cycle ATP could be overproduced by NADH oxidation and most ATP may be in futile cycle, which may be the reason that the yield of glycerol is hard to be improved.

分析发现菌体生长阶段合成丙三醇的代谢流较大，这可能是细胞为了维持高渗透压环境下正常生理功能所需；但是在菌体生长停止后，产丙三醇阶段合成丙三醇的代谢流并没有增加，而是TCA循环中代谢流增加，于是产生的NADH氧化生成更多ATP，大都ATP可能是无效循环消耗掉，这是丙三醇产率没有达到理想产率的根本所在。

We found the relationship among starch metabolism, metabolisms of other components and gene expressing profiling due to the accumulation of sugar. Then, genes expression patterns of starch biosynthesis in leaves and developing endosperms of 5 maize inbreds were studied for the contribution of different genes to starch biosynthesis in endosperm.

为深入了解玉米淀粉合成的分子调控机理，本研究首先以B73、ae/wx和sh1授粉后15天的胚乳为材料，利用18K Affymetrix玉米基因组芯片平台，研究了突变体材料中基因表达谱的变化，发现了淀粉合成受阻后糖的积累对其它物质代谢和基因表达调控的影响；在此基础上，对可能参与淀粉合成的基因以多个自交系为材料，分析它们在叶片和胚乳发育过程中的表达模式，研究了不同成员对胚乳淀粉合成的贡献。
