Molecular characterization and copper susceptibility of Xanthomonas citri subsp. citri strains obtained in Northeast Brazil
The first occurrence of Asiatic citrus canker in Brazil was recorded in the 1950s in the Southeast region. However, the disease has only spread to citrus-producing areas in the Northeast of the country in recent years. Thus, aiming to investigate the variability among 142 strains from this region, we carried out a poly...
