In order to excavate excellent resistant materials to stripe rust, sixty wheat landraces were assessed for resistance to stripe rust Puccinia striiformis West.

为了解小麦抗病品种的基因背景和遗传特点，采用中国目前的条锈菌优势小种对60个小麦农家品种进行了苗期和成株期抗条锈病鉴定。

C591, a common wheat variety originated from India, showed excellent resistance to the dominant races of Puccinia striiformis f.

C591是原产于印度的普通小麦品种，苗期和成株期均对中国小麦生产上流行的条锈菌 Puccinia striiformis f.sp。

Development of markers for wheat stripe rust resistance gene Yr26 Stripe rust, caused by Puccinia striiformis f. sp. tritici, is one of the most devastating wheat diseases worldwide. Development of resistant cultivars is the most economic, effective and ecological approach to control the disease.

小麦抗条锈病基因Yr26的SSR和STS标记小麦条锈病是由小麦条锈菌(Puccinia striiformis f.sp.stritic)引起的一种广泛流行的世界性小麦病害，培育抗病品种是防治小麦条锈病最经济有效且利于环境安全的措施。

Genes for resistance to leaf rust in twenty-four important wheat cultivars from six wheat breeding institutes or companies were analyzed using fourteen isolates of Puccinia triticina.

选用14个具有不同毒性基因组合的叶锈菌系，推导分析了来自山西省6个育种单位和种子部门的24个重要小麦品种所携带的抗叶锈病基因状况。

Soybean variety, temperature, humidity and illumination were factors influencing teleutosorus formation, among which temperature and variety being the major factors.

大豆锈菌可在大豆植株上形成冬孢子和冬孢子堆，田间在10～11月初形成，但数量较少。

Real time RT-PCR analysis showed that in compatible interaction between Pst and wheat, PsCdc2 was up-regulated at early stage of infection. The maximum induction occurred at 12 hpi, at which transcripts were 1.62 fold over that in urediniospore. From 24 to 268 hpi, the accumulation of transcripts decreased steadily.

实时荧光定量RT-PCR结果表明，在亲和组合中，该基因在条锈菌接种小麦的前期上调表达，其中接种后12 h时表达量最高，约为夏孢子中表达量的1.62倍，接种后24-268 h，基因表达基本呈下调趋势，其中96 h基因表达量最低，仅为夏孢子时期的0.07倍。

To CY29, Gaby had one dominant resistant gene whatever it was male or female parent.

结果表明，Gaby有3对基因抗中国小麦条锈菌小种。

The research made it clear that climatic regions of oversummering and overwintering of P.

也有利于指导条锈菌越夏、越冬情况的进一步调查研究。

Jones said: In total, there have been over 130 exemptions granted related to soybean rust control.

琼斯说：在大豆锈菌的控制方面，目前总共已给予了130多种豁免。

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。
