寄生植物

The study of pathogenic genes provides insights into the adaptations required by metazoans to successfully parasitize and counter defenses of immunocompetent plants, and suggests new antiparasitic strategies.

近年来对寄生相关基因的研究遍及南方根结线虫生活的诸多阶段，加之新兴RNA干扰技术取得重大突破，因此深入了解南方根结线虫成功寄生和突破植物免疫防御的机理，寻找新的防治策略成为可能。

Thread made from fibers of the flax plant .

各种非寄生或寄生在植物上的线虫。

A series of interactions such as nematode pathogenicity, host susceptibility and host resistance could form due to parasitism.

寄生过程引起的根结线虫与寄主植物之间的一系列互作反应，包括根结线虫对寄主植物的致病现象，寄主植物的感病反应和抗病反应。

There are 23 species and 3 varieties Orobanche plants in China,most of which are distributed over north,northwest and northeast.The compounds of Orobanche were reported at phenylethanoid glycosides such as acteoside and isoacteoside,and acteoside has significantly protective againstα-galactose induced hepatic injury,which is better than Biphenyl dicarboxylate.

第一部分紫花列当化学成分及生物活性研究紫花列当Orobanche coerulescens Steph为列当科列当属二年生或多年生寄生草本植物，性温、味甘，生长于沙丘、干草原、砾石沙地和戈壁之中，寄生在菊科蒿属植物的根上，具有补肾、强筋之功效，用于肾虚、腰膝冷痛、阳痿遗精和神经官能症等疾病的治疗。

The 111076 nematode individuls were classified into 43 genera and 4 trophic groups. Among them, 32 genera of nematodes belong to beneficial un-plant parasitic (bacterivorous, fungivorous, omnivorous/predatory) nematodes and 11 genera of nematodes belong to baneful phytophagous nematodes which accounted for 1/4 of nematode collectivity, especially the nematodes in the genus of Tylenchus and Filenchus, involved 51 (91%) and 42 (75%) species of flowers, repectively.

经鉴定111076条线虫分属43个属，4个营养类群（食细菌、食真菌、杂食/捕食和植物寄生线虫），其中有益的非植物线虫属32个，有害的植物线虫属11个，占总调查属数量的1/4，相对比例较大，特别是垫刃属和丝尾垫刃属的线虫出现的频率较高，涉及花卉51种和42种，分别占调查花卉总数的91％和75％。

The term is usually used more narrowly to mean MUTUALISM, but many mutualistic associations may have once been parasitic or may become so at some stage in their life cycle, e.g.

此术语多局限于表示共栖，但是大多植物的共栖关系曾转变为寄生关系或寄生关系出现在它们生活周期中的某一阶段。

So the strategies defend against the Meloidogyne incognita infectivity were focus on the pathogenic genes and its products, which may provide insights into the adaptations required by metazoans to successfully parasitize and counter defenses of immunocompetent plants.

因此研究工作的重，改转向研究南方根结线虫寄生相关基因及其产物上。这些研究有助于深入了解其成功寄生和突破植物免疫防御的机理。

Island east, south, 3 free hill are folded on the west emerald green, 85 divisions a variety of 2700 protophyte are lush and green, not only have lofty and forceful tree, also have the bush that hangs down in clusters thriftily, among them not only have the Suo Luo that from dinosaur times shedding hands down such bizarre flowers and trees, still growing up to now the keep on the earth comes down the oldest plant, so-called " earthly plant old longlived person " Long Xieshu, the everywhere of tropical vegetation landscape such as parasitism, bowstring is visible.

岛东。南。西三面漫山叠翠，85科2700多种原生植物郁郁葱葱，不但有高大挺拔的乔木，也有繁茂葳蕤的灌木，其中不但有从恐龙时代流传下来的桫椤这样的奇异花木，还生长着迄今为止地球上留存下来最古老的植物，号称&地球植物老寿星&的龙血树，寄生。绞杀等热带植物景观随处可见。

In the 1990s, he conquered the greatest biological constraint to cereal production in Africa - the deadly weed Striga.

发现了S的寄生的化学基础，他在P培养了许多品种的高梁植物，都是耐旱及搞S寄生的，同时产量也是地方品种的10倍。

Shrubs, usually aerial hemiparasites on other seed plants, often spreading along host by runners, more rarely terrestrial root-parasitic shrubs or trees, nodes not articulated, glabrous or hairy, hairs often stellate or verticillate. Leaves opposite or alternate, stipules absent; petiole often indistinct; leaf blade simple, usually pinnately veined, margin entire.

灌木，通常半寄生在其它种子植物的树上，通过匍匐茎在寄主身上延伸，很少为根寄生的地生灌木或乔木，节没有关节，无毛或有毛，通常为星状毛或具毛轮，对生叶或交替，托叶无；叶柄不明显；单叶，通常羽状脉，边缘全缘。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
