Firstly, the SSH was used to isolate tissues or organs specific expression genes in different development stages of plant. These genes provide evidence for explaining the molecular mechanism of plant development. Then SSH was widely used to isolate genes related to resistance under biological or abiological stress in different plants and the molecular mechanism of the resistance was primarily elucidated.

本文针对悬浮细胞培养中植物细胞剪切敏感性、溶氧及混合困难和次生代谢产物合成能力低等问题，进行固定化长春花植物细胞培养生产生物碱过程的研究，主要涉及固定化方法、影响固定化长春花植物细胞合成生物碱能力因素、及有关固定化长春花植物细胞反应器等问题，应用模糊集理论探讨固定化细胞培养过程的基本规律。

For long-term treatments, the rat administered daily by gavages for six weeks, the results of OGTT showed that guava fruit water or alcohol extracts could reduce the plasma glucose level in the diabetic Wistar rats, however there was on significant difference in insulin level among all tested groups. The results of carbohydrate metabolism showed diabetic Wistar rats administered with 200 or 400 mg/kg BW of guava fruit water or alcohol extracts could decrease more than 15% glucose-6-phosphatase and fructose-1,6-bisphosphatase activities, and it also increase more than 12% glucose-6-phosphate dehydrogenase activities to reduce inhibitory hexokinase from reducing glucose-6-phosphate level.

在醣类代谢方面，实验结果发现糖尿病鼠灌食番石榴果实水及乙醇萃取物六周后，肝脏醣质新生作用中丙酮酸合成肝醣之关键酵素glucose-6-phosphatase及fructose-1，6-bisphosphatase的酵素活性会降低15%以上；另一方面肝脏glucose-6-phosphate dehydrogenase酵素活性则明显增加12%以上，并造成glucose-6-phosphate浓度减少，进而降低其对hexokinase的抑制(因为hexokinase受其代谢产物G-6-P的浓抑制)，因此加速肝脏葡萄糖的糖解作用。

The results show that during the development of the oriental tobacco leaves, the activity of acid invertase was decreased; the changes of GS reached its peak in the 20dans in Samsun, but in the 30dans in Basma and Canik ;the activity of PAL was decreased in the 30dans; The content of total nitrogen was decreased with the mature leaves, but nicotine、total carbon and soluble total sugar were increased. Different varieties, carbon and nitrogen metabolism key enzyme activity and the content of metabolites were different.

结果表明，在香料烟叶片发育过程中，酸性转化酶的活性均呈下降趋势；谷氨酰胺合成酶的活性Samsun品种在20d叶龄时最高，而Basma和Canik在30d叶龄时最高；苯丙氨酸解氨酶的活性均表现为30d时最低；随着叶片成熟总氮含量降低，烟碱含量升高，总碳、可溶性总糖随着叶片成熟其含量呈升高趋势；品种不同，碳氮代谢关键酶的活性及代谢产物的含量变化均有很大差异。
