Subgingival plaque samples were isolated and cultured by the selective medium of black-pigment bacteria, F. nucleatum, Actinomyces viscosus and anaerobium.

临床选取32名种植患者的44枚种植体，记录了修复后1个月，修复后3个月，修复后6个月，修复后12个月四个时段，入选种植牙的菌斑指数，牙龈指数，牙龈出血指数，探诊深度；采用产黑菌、放线菌、具核梭杆菌及厌氧菌的选择性培养基对龈下菌斑标本进行了分离培养。

The results suggested that the hypovir-ulence - associated genetic elements existed in the cells of isolate Ep- 1PN unequally, andsome cells were shortage of the hypovirulence- associated genetic elements.1572 sexual progenies of isolate Ep- 1PN were obtained through single- ascospore -isolation from seven apothecia.

本文对核盘菌Ep-1PN菌株的弱毒特性及其相关特性的遗传特点进行了分析，并评估了Ep-1PN菌株及其弱毒因子防治菌核病的生防潜能，现将结果报道如下

Infection by S. sclerotiorum causes serious damage to oilseed rape, soybean, sunflower and the mustard family vegetables. Because S.

草酸是核盘菌致病过程的决定因子，核盘菌在油菜、大豆、向日葵与十字花科蔬菜等植物上引起严重的菌核病。

Donor bacteria, through its pilus bacteria with receptors contact, the former transmission of different length single strand of DNA to the latter, and in the latter cells for double-stranded or further nuclear chromosome in exchange, integration, so that the latter was the donor of the genetic traits phenomenon.

供体菌通过其性菌毛与受体菌相接触，前者传递不同长度的单链DNA给后者，并在后者细胞中进行双链化或进一步与核染色体发生交换、整合，从而使后者获得供体菌的遗传性状的现象。

It was showed that the growth speed of hypha, sclerotinia production and the pathogenicity of strains had little relation with host and geographical location. The ability of oxalic acid production of strains had positive relation with the pathogenicity. In order to study the nutrition aptness, 8 kinds of culture mediums were tested and the result showed that S.

sclerotinia不同菌株菌丝的生长速度、菌核产量、致病力与其地理来源和寄主来源关系不大，对12个代表菌株的草酸产生能力的测定表明，菌株的草酸产生能力和病菌的致病性基本呈正相关，致病力较强的菌株草酸产生能力较强；采用8种培养基对代表菌株营养条件进行了研究，结果表明核盘菌S。

Simple sequence repeats or microsatellites have been used as genetic markers in population genetics because of their abundance and length variation between different individuals. This study examined the SSRs in the completely sequenced Sclerotinia sclerotiorum and Botrytis cinerea genomes . The occurrences, relative abundance, relative density, most common motifs, and the longest SSRs in the two species were analyzed, and compared with other plant pathogenic fungal species, such as Fusarium graminearum, Magnaporthe grisea and Ustilago maydis .

利用公共的真菌基因组数据库资源，对核盘菌和灰葡萄孢基因组中SSRs的结构类型、分布、丰度及最长序列等进行了系统分析，并与已经研究过的禾谷镰孢菌，稻瘟病菌和黑粉菌等几种植物病原真菌基因组中的SSRs进行了比较。

S. trifoliorum is similar in biology and morphology to S. sclerotiorum , but S. minor produces much smaller sclerotia and generally produces apothecia less frequently in nature.

三叶草核盘菌在生物学和形态学上比核盘菌要小，小菌核产生的菌核非常小并且在自然状况下一般很少产生子蘘盘。

This dissertation aims at finding anticancer and antibacterial polynuclear complexes targeting DNA with high activity and low toxicity. Sixteen compounds were synthesized, and characterized by means of X-ray single crystal diffraction, elemental analysis, molar conductivity and IR, and the influencing factors on structures of the compounds have been investigated. The actions of these compounds to DNA were also investigated by spectral, electrochemical and hydromechanical methods.

本论文以DNA为靶点，以寻找新结构类型的高效、低毒的抗癌、抗菌多核配合物为目标，从分子设计出发，共合成得到了16个化合物的单晶结构，对其进行了结构表征，探讨了结构影响因素，并研究了其超分子结构；采用紫外-可见吸收光谱法、荧光光谱法、电化学和粘度法，从分子水平上研究了所得配合物与DNA的相互作用；在细胞水平上，研究了草酰胺桥联双核配合物的抗菌和抗肿瘤活性。

The extract was further iaolated with LC and purified with preparative HPLC, and uridine, adenosine, and thymidine were obtained.

为了提高菌体中总核苷的提取率，比较了干法和湿法提取对RCEF260菌体中总核苷含量的差异。

Naturally infected plants developed symptoms from water-soaked stem lesions into necrotic tissues that subsequently develop patches of fluffy white mycelium, often with sclerotia and became wilt, typical symptom caused by Sclerotinia sclerotiorum.

综合以上的结果，我们认为PDF1.2的表达动态与拟南芥-核盘菌亲和互作的过程存在对应关系，推出拟南芥对核盘菌的抗性反应可能受茉莉酸／乙烯信号途径调控。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
