锈菌

However, USDA said new computer models indicate that plant pathologists in the Southeast should continue to monitor their area for the fungus, which can quickly defoliate soybean plants and produce yield losses of 80%-90%.

但是美国农业部说，新的计算模型表明，东南部的植物病理学家应该继续监控所在地区的锈菌动态，因为锈菌能迅速破坏大豆叶片，使收获率下降80－90％。

Reaction of 24 Einkorn accessions to mixed inoculum of powdery mildew and stripe rust,and two T.urartu accessions UR204,UR206 and a T.monococcum accession MO205 were used for reaction to a set of 15 differential Blumeria graminis tritici isolates and 21 differential Puccinia striiformis isolates,respectively.Among them,UR206 was resistant to all 15 isolates,UR204 was resistant to 14 isolates except E11,and MO205 showed different resistant types.The results indicated that most likely UR206 and UR204 carried new powdery mildew resistance genes that were different from 18 known Pm genes and MO205 carried new stripe rust gene that were different from 24 known Yr genes.

本研究对24份一粒小麦分别进行了白粉病和条锈病混合菌种苗期接种鉴定，进一步分别用一套白粉病菌菌株(15个)对2份乌拉尔图小麦和条锈病菌小种(21个)对1份栽培一粒小麦进行接种鉴定，其中乌拉尔图小麦UR206能抵抗所有供试白粉菌菌株，UR204除对白粉菌菌株E11感病外，对其余菌株表现抗性；栽培一粒小麦MO205对不同条锈菌小种表现出不同的抗性反应，研究表明乌拉尔图小麦UR206、UR204和栽培一粒小麦MO205分别含有与已知抗白粉病和抗条锈病基因不同的新基因。

The inheritance of haustorium of yellow rust in the durable resistance cultivars was recessive, the degree of dominance was -0.47~-1.83. There were 1~2 genes which controlled the number of haustorium.

小麦持久抗性品种中条锈菌吸器的遗传为部分隐性，显性度为-0.47~-1.83；控制条锈菌吸器数目的基因大约有1~2个。

The results showed that the number of haustorium of P. striiformis in AQ and LB was 44.2/mm2 and 23.74/mm2 respectively. But there was no difference with the number of hastorium of the pathogen between XN (89.83/mm2) and MX (102.02/mm2), which indicated that XN had no resistance to haustorium.

结果表明：AQ和LB中条锈菌的吸器数目分别为44.2/mm2和23.74/mm2，两个品种对吸器均表现较强的抗性；XN中条锈菌吸器数目(89.83/mm2)与MX(102.02/mm2)无差异，未表现出明显的抗性。

So far, rust has been confirmed in kudzu, but not on soybean plants.

到目前为止，野葛中的锈菌已得到证实，但大豆中的锈菌还没有得到证实。

Iowa State plans to capture genetic material at the earliest stages of the infection because the molecular interactions between the soybean plant and the rust fungus at that time are expected to be critical in determining the fate of disease progression.

衣阿华州计划在病原感染的最初阶段截获基因物质，因为在这一阶段，大豆植体与锈菌之间的分子互动对锈菌的发展具有至关重要的作用。

Meanwhile, Sen. Russ Feingold has asked USDA for details regarding its plans to prevent Asian soybean rust fungus from entering the United States and to respond to any appearance of the fungus in the United States.

同时，参议员罗斯·费恩古德已向美国农业部详细询问了有关阻止亚洲大豆锈菌进入美国的计划以及在美国出现锈菌时将采取的对策。

F.sp. tritici can offer consult and help for wheat rust study about variation and evolution.

本研究获得的有关小麦条锈菌群体毒性变异和小种的信息，可以为未来研究小麦条锈菌的毒性变异和群体进化及监测提供一些参考和帮助。

Rust had already been identified in five soybean-producing states, Mato Grosso, Parana, Rio Grande do Sul, Goias and Maranhao, but up until November 19 it was only found in experimental crops or in seeds that germinated from soybeans left from last year's crop.

目前已有五个产豆州发现了锈菌，它们是马托格罗索州、巴拉那州、南里奥格兰德州、果尔斯州和马兰合州，不过在11月19日之前，出现锈菌的还只是一些实验性作物或去年留下来的豆种。

The results indicated that a molecular identification system for the physiological races of Melampsora larici-populina in China could be established through cosmically searching special RAPD fragments of different races.

此结果表明，通过寻找落叶松杨栅锈菌生理小种的特异性RAPD片段，能够建立起中国落叶松杨栅锈菌生理小种的分子检测体系。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
