Xinhua Full Media + 丨 my country's scientific research team found that wheat assisted rust bacteria infection "real murderer"

Xinhua News Agency, Xi'an, July 15th (Reporter Yao Youming) On the 14th, the top international journal "Cell" published an online issue of the Plant Immune Team of the Northwest Agricultural and Forestry University of Agricultural and Forestry Science and Technology after 18 years of research results. The team discovered the sensory genes that assisted rust in infection in wheat, and by knocking on the diseased genes, making wheat was not easily infected by rusty bacteria.

Professor Wang Xiaojie of Northwest Agricultural and Forestry University of Agriculture and Forestry is one of the author of the article. According to its introduction, the discovery and mechanism research of wheat sensing genetic breakthroughs and production application value are the leap breakthroughs that enhance the original independent innovation capabilities of my country's seed industry. "This result breaks the traditional thinking of the current major use of diseased genetic breeding, enriches the gene types available for disease resistance and breeding, and opens up a new way for wheat biochemical breeding, providing technological support for the green prevention and control of modern biological breeding and diseases in my country "Wang Xiaojie said.

Wheat is one of the most widely planted grain crops in the world, providing staple foods for more than 2.5 billion people worldwide. However, pests and pests often cause major losses of wheat output and seriously threaten food safety. Wheat rust is a fungal disease with ingenuity. It has the characteristics of vulnerable and popularity. It is a major biological disaster on the number one in wheat. It is called the "cancer" of wheat. After the founding of the People's Republic of China, there have been 8 times of wheat rust in my country.

Wheat rust disease spreads due to rust bacteria. The scientific research team focuses on the parasitic characteristics of wheat rust bacteria, and tapped the world's first wheat sensor gene TAPSIPK1, which was used by the toxic protein use of germs -coded cytoprocin -based protein kinase. Utilizing gene editing technology, the team precisely knocked out the sensory genes, destroyed the identification and interoperability of toxic protein and sensor genes, and formed the resistance of wheat to strip rust. In the field test, wheat, which was knocked down, was shown to high -anticarring rust.
