镰刀

This paper discussed the pathogens, disease regularity and prevention countermeasures of maize stalk rot, and elucidated that the infection mechanism of maize stalk rot is primary infection source of Pythium spp under high temperature.

论述了玉米茎腐病的优势病原菌、发病规律及其防治对策，阐明了玉米茎腐病的侵染机制是腐霉菌在高温条件下主要的初侵染原，而镰刀菌因其超强的定殖能力而进行二次侵染，两种病原菌侵染致病的主要活性物质为糖蛋白毒素。

The results showed that some strains had effect on the Pythium aphanidermatum, but no effect on Fusarium oxysporum. Seven bacterial strains were obtained which could suppress the hatch of H. glycines.

第一部分真菌激活人角膜上皮细胞FAK信号转导通路的体外实验研究将三种常见致病真菌(白色念珠菌、烟曲霉菌和茄病镰刀菌)分别与人角膜上皮细胞共孵育，MTT法检测FAK信号通路抑制剂染料木黄酮的对人角膜上皮细胞的细胞毒性作用；RT-PCR检测真菌黏附人角膜上皮细胞后不同时间细胞外基质层连蛋白、纤连蛋白、玻连蛋白、Ⅳ型胶原、跨膜蛋白整合素αV、整合素β1(ITGβ1)，以及FAK信号通路中FAK1、FAK2和桩蛋白基因的表达情况；Western blot的方法检测黏附信号转导途径相关蛋白ITGβ1、FAK和PAX的表达，以及染料木黄酮对真菌刺激人角膜上皮细胞FAK信息通路活化的抑制作用；免疫细胞化学方法观察人角膜上皮细胞与真菌相互作用过程中LN、FN和FAK的表达；激光共聚焦显微镜对FN、FAK和PAX进行了细胞定位，并观察真菌刺激后人角膜上皮细胞骨架的变化；流式细胞仪定量检测人角膜上皮细胞ITGβ1与PAX在真菌黏附后表达的改变；光学显微镜观察真菌与人角膜上皮细胞黏附数量，记录并测定了黏附后积分光密度值OD扫描及投射电镜观察了真菌与人角膜上皮细胞黏附后，细胞超微结构的改变。

From the results of our studies we deduced that sucrose itself in the pith tissue of corn stalk could rule as a represser in someway to suppress the pathogen producing enzyme or toxin which can destroy host cells, or it could destroyor inactivate the enzyme produced by the pathogen, or it was not suitable for toxin surviving in it.

同时，从研究结果我们推断蔗糖本身可能具有阻遏镰刀菌产生酶类或毒素作用，病菌在侵染抗病品种过程中可能因寄主组织中蔗糖含量高，而导致病菌产生的可破坏寄主细胞组织的酶类受到阻遏或活性受到钝化；或者蔗糖不利于致病菌毒素的存活。

Was it possible,Cascarellian wondered,that the missing assassin and The Scyt he-Meister were somehow the same person?

卡斯卡利安想，难道失踪了的杀手克里奇和镰刀手-梅司特会是同一个人？

For a long time, they made the most of the driest seas onto get their hay, working sometimes till nine o'clock at night, sedulously paring with their scythes in the twilight round the hummocks left by the ice; but now it is not worth the getting when they can come at it, and they look sadly round to their wood-lots and upland as a last resource.

长久以来，他们乘旱季来临时收割干草，有时劳作到晚上九点，薄暮的微光照在雪化后的小土丘上，他们手中的长镰刀还不停地挥动着。但现在，等水终于干了，草也烂得差不多了。他们悲哀的望着仅余的树林和高地，这是他们最后的资源。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
