1The Isogene 1-Deoxy-D-Xylulose 5-Phosphate Synthase 2 Controls Isoprenoid Profiles, Precursor Pathway Allocation, and Density of Tomato Trichomes显示文摘植物 isoprenoids 从先锋被形成由 mevalonate (MVA ) 综合了在 cytosol 或由 methyl-D-erythritol 4 磷酸盐(MEP ) 的小径在质体的小径。尽管先锋的一些交换发生, cytosolic sesquiterpenes 被假定主要源于 MVA,当 plastidial monoterpenes 从 MEP 先锋优先地被生产时。另外的复杂性在 MEP 小径的第一步产生,它被二分叉的 1-deoxy-D-xylulose 5 磷酸盐 synthase isoforms 典型地催化(DXS1, DXS2 ) 。在西红柿(茄属 lycopersicum ) , SlDXS1 基因无所不在地在而 SlDXS2 抄本充满仅仅很少纸巾,成熟的水果期间与高水平被表示,包括年轻叶子,花瓣,和孤立的毛状体。SlDXS2 表示的特定的下面规定被 RNA 干扰在转基因的植物执行调查反馈机制。SlDXS2 下面规定在在二 sesquiterpenes 的 monoterpene -phellandrene 和毛状体的增加导致了减少。而且,进剩余 monoterpenes 并且进 sesquiterpenes 的导出 MVA 的先锋的加入是由 13C 的比较决定了到 12C 天赋同位素比率被提高。SlDXS1 的一条补偿起来规定没被观察。也展出的下面调整的线增加了毛状体密度并且由喂叶的 Spodoptera littoralis 毛虫显示出更少的损坏。结果在 isoprenoid 先锋分配在 modulating isoprenoid 新陈代谢和显著粘性揭示 DXS2 的新奇、非冗余的角色。Heike Paetzold Stefan Garms Stefan Bartram Jenny Wieczorek Eva-Maria Uros-Gracia Manuel Rodriguez-Concepcion Wilhelm Boland Dieter Strack Bettina Hause Michael H.

2重型工矿内燃机车用Voith液力换向传动装置显示文摘德国Voith公司早在1965年就生产出了L2r3型液力换向传动装置,并在一台240马力的调车机车上进行装车试验。在此基础上,VOith公司相继开发研制了5种不同功率等级的液力换向传动装置,其功率范围从用于小型调车的150kW到用于大型通用内燃机车的1400kW。本文着重介绍功率最近又得到进一步提高的4型和5型Voith液力换向传动装置。对4型液力技向传动装置进行了加装电子控制系统的现代化改造,从而可满足下列要求:1)可实现起动变矩器Ⅰ和运转变矩器Ⅱ的工作状态的转换以及相应于不同运行方向的转子A和B转向的转换,其中包括传动装置的监测;2)液力传动装置可在两个速度档进行工作:第一档(慢速档),可以非常低的运行速度进行驼峰调车场通常的调车作业;第二档,可用于中等距离内重载货物列车的干线牵引作业;3)发动机和传动装置密切配合,通过一套快速反应的车轮防滑装置,以避免在潮湿轨道上车轮打滑,改进机车的粘着性能。本文介绍的两种工矿机车都是这种大功率液力换向传动装置应用的典范。第一种机车为德国MaK公司生产的G1205BB型内燃机车,它有两个速度档,可在运行中任意转换。第二种机车是由中国资阳内燃机车厂生产的新型六轴转向架式内燃机车。最后介绍了液力换向传动装置在工矿内燃机车中的运?WOLFGANG PAETZOLD 孙慧云 1995国外内燃机车1995,,9:5
3The odd one out or a hidden generalist:Hawaiian Melicope (Rutaceae)do not share traits associated with successful island colonization显示文摘Oceanic islands are unique in their species composition,which is defined by arrival of colonizers via long distance dispersal followed by establishment of species followed in some cases by adaptive radiation.Evolutionary biologists identified traits facilitating successful colonization of islands as including polyploidy,self-compatibility, herbaceousness and ability for long-distance dispersal.Successful establishment and evolutionary diversification of lineages on islands often involves shifts to woodiness and shifts in methods of outcrossing as well as changes in dispersal ability.The genus Meflicope colonized numerous archipelagos throughout the Pacific including the Hawaiian Islands,where the lineage comprises currently 54endemic species and represents the largest radiation of woody plants on the islands.The wide distributional range of the genus illustrates its high dispersibility,most likely, due to adaption to bird dispersal.Here we investigate ploidy in the genus using flow cytometry and chromosome counting.We find the genus to be paleopolyploid with 2n =4x =36,a ploidy level characterizing the entire subfamily Amyridoideae and dating back to at least the Palaeocene.Therefore Hawaiian MeHcope have not undergone recent polyploidization prior to colonization of the islands.Thus Nlelicope retained colonization success while exhibiting a combination of traits that typically characterize well established island specialists while lacking some traits associated to successful colonizers.Claudia Paetzold Michael Kiehn Kenneth R.Wood Warren L.Wagner Marc S.Appelhans 2018Journal of Systematics and Evolution2018,56,6:2
