Similar to rice and barley, and has allowed scientists to confirm which genes can suffer from two main types of barley to avoid the disease, such as the large wheat mildew and stem rust.

稻米和大麦的相似性，已使科学家确认，哪些基因可以使大麦避免罹患两种主要的病害，比如大麦粉霉病和茎锈病。

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%。
