Abstract
Bacteria use specialized secretion systems to translocate substrates to the environment or to other cells. Secretion systems are supramolecular complexes located at the bacterial cell wall. The Type IV Secretion System (T4SS) is involved in translocation of virulence factors, bacterial conjugation and uptake or release of DNA. Xanthomonas citri pv. citri (Xac) is a gram-negative bacterium…
