Integrated outlook of proteins secreted between 1-5DAI. a During the first hours of infection, secretion system structural proteins, and proteins related with motility and quorum sensing are secreted. After recognition of PAMPs, a cascade of reactions culminates in the activation of PTI in order to avoid penetration of bacteria inside plant tissues increasing the ROS production during POB. Subsequently, Xac secretes effector proteins to overcome plant defenses and promote bacterial virulence. These processes may occur between 0 and 24 h after infection. b After 24 h of infection, Xac secretes higher amounts of proteins related with reactive species depletion and osmotic adaptation (ROSd/OSM), iron uptake and metabolism, biofilm formation, and LPS modulation in order to protect themselves against the stress caused by POB. c After activation of virulence related proteins during the first 24 h (pink), a protein repertoire involved in ROS depletion, EPS biosynthesis and LPS modulation, iron uptake and metabolism, and biofilm formation is active and working in an integrated manner between 1 and 5 DAI
