In the T1 generation, ten from 30 plants showed kanamycin-resistance. And, PCR amplification confirmed that 8 plants of them had specific fragment of chitinase, but no specific fragment ofβ-1, 3-glucanase. In this study an amaranth agglutinin gene was also cloned from Amaranthus retroflexus for obtaining aphids resistant transgenic cotton.

Genetic cluster analysis is similar based on the results of morphological and DNA markers, the five populations could be divided into three groups. But there are different groups sort of individual locations, reflecting the similarities and difference about the analysis of the relationship between population with the two kinds of markers, It could be concluded that there was coupling and relevance to some extent in evaluating genetic diversity with the same experiment sampling by morphological and SSR marker variation. However, there was also differences. In research, the two can complement each other.8. Identification of Genetic Relationship of Amygdalus plants by SSRThe genetic relationship among 55 Amygdalus plants collections, belonging to 6 species and collected from both homeland and abroad were identified via SSR molecular marker technique.

新疆野扁桃遗传多样性不同研究分析方法结果的比较与评价表型与DNA二种水平的遗传标记方法揭示的遗传多样性水平有差异，表型性状比DNA分子标记具有更大的变异性；其受到环境的影响较大，也即对环境更敏感。2种水平的遗传标记聚类结果将野扁桃5个不同分布群体均可分为3个大类群，但是出现有个别不同的群体排序位置，反映了2种标记在分析种群间关系上的异同性，从本研究结果来看，说明表型与DNA标记有一定的耦合性和相关性，但也存在差异，在研究上可以互为补充。8。

After analysis of a large number of scientific research and found the secret of the water and plants from the Oak Hill-watt, water is from the highly magnetic stones in flowing natural spring, infiltration; plants for Antheraea Mountain Watt of ginseng in the forests,, Ophiopogon japonicus, such as Ganoderma lucidum.

The third part is not only the function and principle of medicine, anticancer and antioxygen activity of different kinds of natural products such as resin ,essential oil, high molecule, grease and so on but also their application. The fourth is security problem of Plant Natural Products. Through the lessons, we can correctly understand and use the relationship between plants and environment.

其课程分为13章，内容主要分为4大部分，一是阐述植物天然产物的发生机理和代谢规律，介绍相关主要植物种类，并对天然产物进行化学分类；二是讲述植物天然产物和自身生长发育之间的关系、天然产物如何影响植物之间的相互关系、以及植物如何利用天然生物活性物质抵御病虫害的威胁；三是详细描述了各种天然产物，如植物自身生长发育过程中所产生的活性物质、植物与其它生物之间的相互关系中所产生的生物活性物质、植物毒性物质、植物药理活性物质、植物抗生物质、植物树脂、植物精油、植物高分子、植物油脂、植物抗氧化活性成分等，并阐述它们的药理活性、抗癌性、抗氧化性等对人类健康起作用的的功能和原理；四是提出了植物天然产物的安全性问题，并介绍相关案例和介绍相关法规；在此基础上还专门讲述了树脂、精油、高分子、以及油脂类等天然产物的应用。
