Microbes present in the soil can be fundamental to activity, as opposed to plant diseases. This is what some researchers at the University of York have found out, that Ralstonia solanacearum, the pathogen that causes bacterial fading of plants, does not infect all plants or crops, and this is due to the action of the present microbiome.

This bacterium causes disease, especially in tomatoes and potato plants, and results in huge economic losses in virtually every region of the world, from Africa to China. The very “irregularity” of these infections in the fields has prompted researchers to study the relationship between these bacteria and microbiomediated plants or other bacteria present in the soil.

By examining individual plants in an indistinguishable manner, the researchers compared the microbiomes of the soil in which the plants lived before and after the symptoms of the disease. The researchers found that plants affected by the pathogen and survived, compared to the dead, can count on certain soil macrobiotics, which saw the presence of rare taxa pseudomonas and bacteria bacillus, which were going to suppress pathogens.

Of course, this discovery can be used to transplant soil to make plants more resistant to this type of disease.

In addition, this study shows that it is important to focus not only on pathogenic bacteria but also on beneficial ones, and this applies not only to humans and animals, but also to plants.
