查询词典 wheat black stem rust

With conventional PCR primer pair XBFF/R,the same 352bp bands appeared by amplifying all the DNA samples from the eight races,and no bands appeared by amplifying all the DNA samples from the 9 plant pathogen species(Cucumber powdery mildew,wheat yellow rust,wheat leaf rust,wheat stem rust,wheat scab,wheat sheath blight,wheat loose smut,maize sheath blight and maize head smut)and control.

3用常规PCR和实时荧光PCR两种方法对温室接种的小麦白粉病进行了检测，并在时间上与自然显症的观察进行了比较，结果表明：在温室条件下，小麦白粉病菌在接种后第5d时开始出现小麦白粉病病斑，而利用常规PCR引物XBFF/R可在接种第3d检测到小麦白粉病菌，比自然显症观察能够提前了2d检测到白粉病菌；实时荧光PCR法可在接种后1d即能检测到小麦白粉病菌，比自然显症观察能够提前了4d检测到白粉病菌，这可为白粉菌的预测或预警检测提供依据，更可为白粉病在流行前制定防治决策赢得宝贵时间。4。

Neural stem cells have a strong self-renew mechanism and it can transform after a little break. Neural stem cells have a long term survival, which mean that it has more probability of wrong copy than mature cells. These cells are formed glioma stem cells in the end. The genes who adjust neural stem cells can express in glioma stem cells, which hold out glioma stem cells from neural stem cells. There is another presume that glioma stem cells come from differentiated cells. Through the gene break of these cells, they can obtain characteristics of stem cells, then form glioma stem cells.

神经干细胞具有很强的自我更新机制，获得较少突变即有可能恶性转化，而且干细胞存活时间较长，这意味着干细胞比成熟细胞发生细胞复制的错误几率更大，因外界环境的刺激而发生突变的机会更多，最终形成脑胶质瘤干细胞，同时调节神经干细胞增殖和自我更新的基因在脑胶质瘤的脑胶质瘤干细胞中也表达，这也是支持神经干细胞是脑胶质瘤干细胞来源的；也有推测认为它可能起源于已分化的细胞，由这些细胞突变发生去分化得来，并通过基因突变而获得了干细胞自我更新的特性，从而形成脑胶质瘤干细胞。

Ug99 could be called a superior virulent race to widely-used and Sr31-carrying Chinese wheat cultivars or stem rust resistant sources.The number of virulent genes contained in Ug99 was more than the total carried in all Chinese stem rust races.For instance,the virulence of Sr5,Sr9e or Sr11 was the typical races.However,besides the virulence of Sr5,Sr9e and Sr11,Ug99 contains additional virulence of Sr21,Sr31and Sr38,which have never been found in Chinese stem rust races.

Ug99堪称我国的超毒小种，我国最典型的秆锈菌小种只能分别克服或Sr5或Sr9 e或Sr11单基因抗性，而Ug99不仅具有Sr5、Sr9 e、Sr11的联合毒力，而且还具有Sr21、Sr31、Sr38的联合毒力，而我国从未有小种能克服后者的抗性。1B/1L(含Sr31)易位系曾是我国使用的重要秆锈抗源，必对Ug99高度脆弱，我国118份小麦品种在KARI的测定结果表明，高感品种频率98.3%。

However, the transformation rate from dominant stem to overtopped stem and from overtopped stem to dominant stem were the lowest. The interconversion of classified stem would increase as the stand density and the rate of L. gmelinii was going up. The altitude that classified stem mainly concentrated was less than 1000m, slope was less than 25°, aspect was south slope, position was at middle and lower, soil depth less than 17cm. The rate of no interconversion was 66.7% among overtopped stem. It should cut the overtopped stem as intermediate cutting.

优势木转被压木和被压木转优势木的转换率最低；随着林分密度和林分中落叶松比例增加，分级木相互转换数也增多；分级木转换现象主要集中在海拔＜1000m、坡度＜25°、坡向为阳坡、坡位为中下、土壤厚度＞17cm的林分中；被压木中，无转换的占66.7%，抚育采伐时应考虑伐除这些被压木。

Dr Michael Ayliffe from the CSIRO says the secret to rust resistance might be found in rice."Rice doesn't get infected by any rust pathogens which makes it very atypical in that sense," he said."So we're trying to work out what are the genes responsible for this resistance."The bigger picture would be to see if we can transfer them to wheat and see if they can provide a level of resistance to wheat stem rust.

联邦科学与工业研究组织的艾立夫博士表示抗锈病的机理很可能会在水稻中发现，水稻的特殊之处在于它不会被任何锈病抗原感染，所以他们正在竭力在水稻上寻找抗锈病基因，更关键的是看看能否把他们转移到小麦上并能产生一定的抗性。

Genetic analysis were carried out to identify powdery mildew and strip rust resistance genes in the F2 of Am6-4 amphiploid and wheat variety Jinan17. Results showed that resistances to powdery mildew and stripe rust were controlled by a single dominant gene respectively. 124 SSR primers from genome D were used for marker analysis, marker Xgwm98 150(150为下标) from the chromosome 6D was found to be linked to the new powdery mildew resistance gene with a linkage distance 20.42 cM; A special DNA band was amplified by primere xgwm33 in resistant stripe rust plants, resistance gene for stripe rust was localized on chromosome 1D, and the genetic distance between resistance gene and marker is 8.0 cM.
