Summary:
Bacterial speck disease, which reduces both fruit yield and quality, has been a growing problem in tomatoes over the last five years. Because the culpable bacterium, Pseudomonas syringae, prefers a cool and wet climate, crops in places such as New York State have been particularly susceptible. Researchers have uncovered the first known gene to impart resistance to a particular strain of the bacterium that causes speck disease.Bacterial speck disease, which reduces both fruit yield and quality, has been a growing problem in tomatoes over the last five years. Because the culpable bacterium, Pseudomonas syringae, prefers a cool and wet climate, crops in places such as New York State have been particularly susceptible.

Recent research at the Boyce Thompson Institute headed by postgraduates Carolina Mazo-Molina and Samantha Mainiero and overseen by faculty member Greg Martin may change this. Published in the August issue of The Plant Journal, their work has uncovered the first known gene to impart resistance to a particular strain, called "race 1," of the bacterium causing speck disease.

Another resistance gene, Pto, which provides resistance to race 0 strains of Pseudomonas syringae, has been used for over 25 years. However, crops remain vulnerable to the increasingly common race 1 strain, resulting in significant losses for growers.
