In a study published in the Journal of Bacteriology, scientists have identfieid a gene in the bacterium Erwinia carotovora, that influences its ability to infect and damage crops.
E. carotovora causes blackleg and soft rot in potatoes, but may also infect other crops such as carrots, tomatoes and onions.

E. carotovora causes blackleg and soft rot in potatoes, but may also infect other crops such as carrots, tomatoes and onions.
"We have shown that the production of cell wall degrading enzymes is genetically linked to not only signalling abilities but also to the bacterium's nutritional status. This has important implications for researchers looking for new ways to control the disease. By improving our understanding of how Erwinia carotovora rots the plant, we can reveal additional, possibly novel targets for the eventual development of anti-rot agents. We have also opened up the potential to develop pesticides."
