Copper-induced stress mechanisms in Erwinia amylovora: a comparative phenotypic and transcriptomic study using copper-sensitive and -tolerant strains.

Abstract excerpt

Erwinia amylovora causes fire blight of apple and pear. Among the management strategies, copper-based treatments are widely used to control the disease. However, the impact of copper on the pathogen is not uniform, and different strains show different tolerance levels to the heavy metal. Upon identifying E. amylovora strains with unusually high (EaR2 and Ea17) and intermediate (Ea19) copper sensitivity, we...
