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。

锈病是结缕草属植物上的重要病害，使草坪景观遭到破坏，散出的夏孢子污染游人的衣物，甚至导致过敏，极大地影响了人们对草坪的利用，而目前只是通过定期的喷施农药来进行锈病的防治，既不利于人们的健康，又对环境带来负面影响。

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。

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%。

In addition, there are two strands of the head is also black, and are rust, rust can be seen because of lead wire resistance increases, resulting in the signal can not be smooth, telephone through the audio signal, the low band signal can also only phone, there is always the voice of flap, and the use of the ADSL band signal is relatively high, head through the rust on it is very difficult, leading to slow or stop signal transmission.

此外有两处绞合的线头处也发黑了，都是锈，可见正是因为导线生锈导致电阻增大，导致信号不能畅通，电话通过的音频信号，频带低，信号还能通过，只是电话里老是有啪啪的声音，而ADSL的信号使用的频带比较高，线头生锈了就很难通过，导致信号传输变慢或者断流。
