Abstract
Xanthomonas citri subsp. citri (Xcc) is the causal agent of citrus canker, a disease that affects almost all types of citrus crops. Production of particular pathogenicity factors in Xcc is regulated by rpf gene cluster, which encodes elements of a cell-cell communication system called Quorum Sensing (QS). The QS in Xcc is mediated by a diffusible signal factor (DSF). Recently we have show…
