Wheat can be vulnerable to diseases that may increase with high temperatures. A team of scientists may have found on five continents a way to help wheat again, according to two souls published in the magazine sciences.
“Climate change causes diseases in the previously invisible places,” said Brandi Wolf, a researcher at King Abdullah University of Science and Technology (KAUST) in the Kingdom of Saudi Arabia and the author of the study. press release. “We need more study of plant immunity to develop technologies that will protect valuable food crops.”
An urgent need to increase plant immunity
Wheat provides food for billions of people as well as the animals they eat. But grains are vulnerable to infectious diseases, just like humans and animals. Stem rust – which is sometimes called “polio of wheat” – historically killed crops and played a role in many famines. Scientists have developed some of the disease -resistant wheat strains, but pathogens that affect plants can be transformed and evolved.
As in humans, plants use their immune devices to resist infections. To help plants do this more effectively, scientists first need to understand how the disease controls and destroys them.
The new search does so completely. It separates how the molecular mechanism in the vegetable cells responds to the rust of the stem, which features brown tiles on wheat stems and leaves. the The first paper It describes how the mechanism works. the The second study It looks at how to fight these molecular machines for multiple forms of fungi harmful to plants.

Discovering a wheat protection strategy
According to the press statement, the team of scientists at five continents led by WULFF, wheat engineering, is trying to be fortified against infection.
Kinaz is the key. These molecules, which are found in many living organisms, work as a cellular high. They transfer other auxiliary particles to the correct part of the cell. Often, as soon as they reach their destination, it leads to a complex sequence of molecular events. Basically, as soon as the appropriate molecule reaches its destination, it works after that as a finger that knocks the first domino in a complex design.
Understand how wheat reacts
The surprise in this study is that not one, but two hands -handled kinaz together participate in the immune response to wheat. This is the first time that this mechanism has been observed, according to the paper.
When there are no pathogens, the quinazan is linked together – and thus like the handcuffs. This makes them inactive.
But when the nurse is associated with one of the two, it acts effectively as a key, and it opens both toothpicks. Understanding how this mechanism may help cultivate engineers for engineers – and possibly other crops – to spread this mechanism, and perhaps against multiple diseases – not just wheat rust.
“The majority of countries see wheat as it is very important for their food policy and food security,” said Wolf. “The more we understand how wheat interacts with pathogens, the more we can secure food supply for the growing population in the world.”
