Our previously study has been showed that transgenic N.benthamiana and N.tabacum plants expressing TYLCCNV DNAβC1 developed pleiotropic morphologic abnormalities such as leaf curling,distortion and interveinal protuberances on the abaxial surface. To determine whether theβC1 protein of TbCSY is also responsible for symptom induction,we prepared transgenic N.benthamiana and tomato plants expressing the TbCSV DNAββC1.Of the rooted plantlets,only 10%of transgenic N.benthamiana plants were moderately abnormal,including upward leaf curling.

DNAβ互补链上编码一个保守的ORF，即βC1，对TYLCCNV DNAβ的βC1的突变发现它编码一个症状决定因子，表达TYLCCNV DNAβ的βC1的转基因烟草产生曲叶、畸形和叶背面组织增生等发育异常的表型，而大部分转化TbCSV DNAβ的βC1基因的烟草和番茄植株均与正常植株类似，只有少数烟草表现出轻微叶上卷表型。

Several anti-tumor cell lines and carbonic anhydrase Ⅱ model were established. More than 10000 compounds and extracts from plants were screened using these models and about 10 compounds showed strong inhibitory activities. Two species of plants Inula helianthus-aquatica and Saussurea deltoidea were chosen to investigate chemical and bioactivity constituents based on the results of screening of extracts and fractions. 58 compounds were isolated and identified from these two plants, 6 compounds were found to be new and 14 compounds showed anti-tumor activities. We also studied the anti-tumor mechanism of the compound bigelovin isolated from Inula helianthus-aquatica. Bigelovin was found with apoptotic activity against cell line U266 by lowering the amount of important transcription factor E2F-1 which inhibits the cell cycle at G0/G1 stage. Docking study on 7 natural new phenolic inhibitors of CA Ⅱ and 3D-QSAR study on 61 sulfonamide inhibitors of CA Ⅱwere also investigated. The calculated results were in good correlation with experimental results.

基于以上两种重要疾病和研究组方向，本论文工作开展了多个肿瘤细胞株和碳酸酐酶Ⅱ靶标模型的建立和筛选工作，累计筛选1万多个/次样品，发现10余个活性较强化合物；从粗提取物筛选结果中选取两种抗肿瘤活性强的菊科植物水朝阳旋覆花(Inula helianthus-aquatica)和三角叶凤毛菊进行了系统化学和活性成分研究，分离鉴定了58个化合物，发现6个新化合物和14个抗肿瘤活性化合物；通过合作对水朝阳旋覆花中活性较强的bigelovin进行了抗肿瘤作用机制研究，发现它可能是通过降低G2期重要的转录因子E2F-1，致使细胞周期阻滞在G0/G1期，引起多发性骨髓瘤U266细胞凋亡；开展了7个新的天然酚类CAⅡ抑制剂的对接研究和61个合成的系列磺酰胺类CAⅡ抑制剂的3D-QSAR分析，结果表明计算与实验一致。

As to'Cabemet Sauvignon'and'Queen of Vineyard', which belong to the'West Europe Cultivars Group', no obvious decline of Fv/Fm was found in their potted plants even under severe drought stress. Their photosynthetic abilities also greatly recovered after rewatering, i. e. no serious photodamage was formed in these cultivars under drought stress. Between them, the φPSⅡ of 'Queen of Vineyard'under severe drought stress was much lower than that of'Cabernet Sauvignon', which suggested that the light use efficiency of the former was much lower than the latter under severe drought stress. The potted plants of'Autumn Royal'and'Rizamat' sustained high Fv/Fm and φPSⅡ before moderate drought stress, but seriously declined under severe drought stress, which indicated that these cultivars had a weak resistant ability to extreme drought stress. A hybridized cultivar of Vitis vinifera L. and V. labrusca L.,'Red Double Taste', its Fv/Fm and φPSⅡ expressed mild decline along drought stress grade.φPSⅡ of'Red Double Taste'was the highest among seven cultivars under severe drought stress condition, which might closely connected with its high photorespiration activity. Another new cultivar,'Red Globe', and a rootstock,'1103Paulsen', the Fv/Fm and φPSⅡ of their potted plants declined markedly under slight drought stress, which suggested that they held a weak ability to defend against photoinhibition.

西欧品种群的赤霞珠和葡萄园皇后，其盆栽苗的Fv／Fm直到重度干旱胁迫下仍没有明显的降低，且复水后光合能力恢复程度较高，即干旱没有给这两个品种造成严重的光破坏，而两个品种之间，葡萄园皇后在重度干旱胁迫下的φPSⅡ明显低于赤霞珠，说明其光合器官在严重干旱胁迫时对光能的利用率较差；新品种皇家秋天和东方品种群的里扎马特在中度干旱胁迫下仍可维持较高的Fv／Fm和φPSⅡ，但在重度干旱胁迫下则降低幅度较大，说明其抵御极端干旱胁迫的能力较差；欧美杂种红双味的Fv／Fm和φPSⅡ随着干旱胁迫程度的增加呈现平缓的下降趋势，而且其φPSⅡ在重度干旱胁迫下是七个品种中最高的，这应该与其此时仍维持较强的光呼吸活性有关；红地球和砧木1103Paulsen的Fv／Fm和φPSⅡ在轻度干旱胁迫下就明显下降，表明干旱条件下其抵御光抑制的能力较差。

In the 2-year field experiments, host plant preference and dispersal of the rice water weevil adults of the 1st generation emerged from the 1st cropping season rice were measured on newly transplanted plants of different species and/or growth stage. The weevil preferred significantly to barnyardgrass over Leersia herxandr and Cyperus difformis L with rice at the least, while the age of the plant did not affect such preference. But mean size of feeding scar in on younger plants were larger than in older plants.

在田间自由选择条件下，一代稻水象甲成虫对稗草的选择性显著高于对水稻的选择；稻水象甲对不同生育期的稗草、水稻的选择没有显著影响；对李氏禾和莎草的选择高于水稻，低于稗草；较幼嫩的植物上的取食斑总长度、取食斑平均长度比较老的植物的要长。

The researcher finds that the use of ethno plants of the ancestors is amazingly wise, and it also respects the harmony of nature. The masculine plants with large number and fast growing are mostly used, such as Miscanthus and .Macaranga. used as firewood. As to the plants growing more slowly, ancestors cherished them and used them effectively and appropriately according to their characteristics.

民俗植物调查的结果发现先民对植物的利用是很有智慧的，也十分能尊重自然的协调，对於族群大、生长快的阳性植物常使用得最多，例如五节芒、野桐、白匏子等大量使用於薪材；对於生长慢数量少的植物，则珍惜资源有效使用，充分了解依据植物生长的特性，做适时适当的运用。

In general, sunflower was suited to phytoremediation of moderately Pb-contaminated soil by phytoextraction.The result mentioned above showed that the main reasons that nutrient and EDTA could impact on phytoremediation efficiency was these as below: firstly, the addition of soil amendments transform soil Pb from nonresidual fractions to residual fraction substantially. Secondly, the grown period of tissues in C4 plants was short, so the replacement of C4 plants with C3 plants may increase times and efficiency of remediation.

根据上述结果，不同营养水平和EDTA对铅污染土壤植物修复的机理及效率可以归纳为：N、P、K的添加能使土壤中的非残留态Pb向残留态转化，因此N、P、K的添加能够增加菠菜和苣荬菜体内的铅积累；与C3型植物菠菜、苣荬菜相比，C4型的植物马齿苋由于构件成熟期短，较为适合作短期内铅污染土壤修复工程；在植物修复过程中，低浓度EDTA的分次添加能够显著提高修复的效率，并且能够减小螯合剂增加产生的二次污染。

The optimal boron concentration for growth of pea (Pisum sativum L.) andcucumber (Cucumis Sativus L.) plants was screened by designing a series of boronconcentration in nutrient solution and the influeuce of boron deficiency or toxicityon integrity of cell membrane in different organs of the two plants was studied bymeasuring pH of the nutrient solution,〓 concentration and conductance in rootexudate solution and extracting solution of different organs from the two plants.
