Plants fight off pathogens through "food shortages", the discovery is expected to develop new pesticides

When pathogens such as bacteria invade plants, they will absorb the sugar produced and accumulated during plant photosynthesis
.
Researchers from Kyoto University and other institutions in Japan have discovered that there is a protein in Arabidopsis leaves that can transport sugar from outside the cell to the inside
.
When pathogens such as bacteria invade, Arabidopsis will initiate a defense response mechanism, and the role of this protein will become stronger, recycling the sugar from the outside of the cell to the inside
.
This is equivalent to the plant's defense purpose by "cutting food" to bacteria and other pathogens
.
In the experiment, the researchers artificially destroyed the function of this protein, and found that the number of bacteria has increased significantly, and the disease of Arabidopsis is more serious
.
Researchers believe that this mechanism should also exist in other plants, and this discovery will help develop new pesticides that help plants resist pathogens
