New findings could stop the spread of rice pestilence bacteria

plague is one of the main diseases of rice. A specific protein activity that inhibits rice pestilence bacteria can prevent transmission between rice cells, international researchers have found.
rice pestilence is caused by fungal infections that can cause rice strains to shrink or die. Up to 30 per cent of the world's rice production is lost to rice pestilence each year, equivalent to rations for 60 million people. The new findings will help to gain an in-depth understanding of the mechanisms of rice pestilence and develop practical means of disease resistance.
rice pestilence bacteria attack rice cells with mycelium, replicate more mycelium within the cells, and then pass through tiny connection channels between cells - intercellular filaments that secretly infect other cells and are not attacked by the rice immune system.
The University of Exeter in the United Kingdom issued a press release on the 26th, the University of Kansas and other institutions in the United States researchers found that chemical genetics to inhibit the activity of the rice pestilence bacteria PMK1 protein, can bind the bacteria inside the cell, preventing it from infecting other cells.the
study found that the PMK1 protein regulates the expression of a range of genes, some of which suppress the rice immune system and prevent it from identifying and attacking rice pestilence bacteria, and others that allow the bacteria to have a "shrinking function" that can shrink so small that they can travel through the pipes of intercellrystic wire.
a major discovery, but it is not yet possible to apply it to the real world, according to researchers. On this basis, they hope to find the target of the PMK1 protein and find out the molecular mechanism of rice plague.
