U0126 and TFP could suppress the appressorium production of S. turcica in glass slide and corn leaf surfaces independently or mixed-treated. The effect was dose-dependant and would be disappear when 500μM cAMP was added.

但加入cAMP后，它们的抑制作用消失，从而表明，MAPK途径与Ca〓-CaM途径和cAMP途径间即有协同作用，又相互影响，它们之间组成一个复杂的信号网络调控玉米大斑病菌的分生孢子和附着胞发育。

GFP signals were observed in nuclei of conidiophore in transformants expressing the HTF1-GFP fusion construct.

Htf1-GFP融合蛋白的亚细胞定位分析也表明其GFP信号在分生孢子梗的细胞核中突然明显的增强表达。

Cinnamaldehyde and citral have directly or indirectly interfered the conventional synthesis of fungal hereditary DNA and RNA and normal differentiation of conidiophore in A. flavus and A. fumigatus, thus inhibiting the normal cell cycle and the growth and propagation of fungi.

肉桂醛、柠檬醛直接或间接影响了真菌细胞遗传物质的正常合成，以至不能完成正常细胞周期，影响分生孢子梗的正常分化，从而抑制真菌生长、繁殖。

The Cork was consisted of five or six layer long cells. The secondary phloem occupied 46% of the diameter of root, and the parenchymas cell was abundant of the inclusions. The secondary xylem consisted of vessel, xylary radial ,and a little of xylary parenchyma cells. Some segment of hypha, swelled hypha, pelotons and conidiophore were colonied in cork and secondary phloem.

周皮由木栓层，木栓形成层和栓内层组成，其中木栓层由5～6 列长形细胞组成；维管组织中次生韧皮部所占根径的比例达46%，其薄壁细胞中内含物较丰富，次生木质部中分布有导管和木射线及少量木薄壁组织；在格木木栓层和次生韧皮部中分布有菌丝片段、膨大的菌丝和菌丝团及分生孢子。

The biological polymorphism of Cercospora zeae-maydis was studied systematically in the levels of histology, protein and DNA. The major characters in polymorphism of pathogen were listed as follows:(1) The great differences were seen in shapes and sizes of conidiophores, the growth velocity of mycelium and pigment-productivity of colony among pathogen strains. In addition, an albino strain, a kind of mutant, was casually discovered during isolation of pathogen from diseased plants, which supported strongly our previous prediction that there should be some potential genetic variation in Cercospora zeae-maydis.

本研究在组织学、蛋白质和DNA水平上，系统研究了玉米灰斑病菌的生物学多态性，这种多态性主要表现在以下几个方面：①病菌形态学和培养性状多态性：菌株间存在分生孢子形态、菌丝生长速度、菌落产色素能力等方面的差异，该病菌在自然界存在另一种变异类型——白化菌株，说明灰斑病菌的确存在遗传变异的潜能。

Are the most common contaminants and are easily detected by presence of a glistening bacterial slime or characteristic fungus conidia.

细菌及数种杂常会造成污染，这很容易从发亮的细菌黏质，或特有的真菌分生孢子来侦查。

The initial time of the conidial germination at 100% RH advanced as the temperature increased.

在100%RH下，分生孢子始见萌发的时刻随着温度的升高而提早。

The macroconidium of the 11 isolated strains showed as spindle shape or sickle shape, in the metabolites of the strains, there was no C.

分离出的11株菌株的大型分生孢子呈纺锤形或镰刀形，其代谢产物通过薄层层析，没有检测到长春花生物碱。

The results showed that resistant gene Ht in F1 heterozygote was the most effective on controlling spots number and size; all monogene in heterozygote could produce spore by moisture culture and resistant gene Ht1 was the most effective; resistant gene Ht1 in medium level, Ht3 in high level, and Ht in low level of vertical resistance of heterozygote, were the most effective on controlling spots spread; while Ht2 in high level of vertical resistance of heterozygote was the most ineffective on controlling spots spread; and all resistant monogene in heterozygote showed superior to their parents on controlling incubation period and gene Ht was more significant than other genes.

结果表明，抗性单基因Ht处于F1代杂合状态时，控制病斑数和病斑面积的效应最强；单基因处于杂合状态时，湿培48h病斑全部能产生分生孢子，且处于同一水平抗性杂合状态时，Ht1控制产孢量的效应最强；Ht1处于中水平、Ht3处于高水平和Ht、处于低水平垂直抗性杂合状态下，控制病斑扩展效应最强；而Ht2处于高水平垂直抗性杂合状态下，控制病斑扩展效应最弱；抗性单基因处于杂合状态下，控制潜伏期多表现超亲现象，Ht控制病害潜伏期比其它单基因显著。

Using of agarose-embedment lysis cell wallmethod for preparing intact chromosomal DNA from phytopathogenic fungi is thefirst time.

首次采用凝胶包理破壁法由植物病原真菌分生孢子获得完整染色体DNA，克服了先用裂解酶破壁获得大量原生质体再用琼脂糖包理原生质体的传统制备方法的一些不足。

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。
