SRP310986 PRJNA715040 IMMUNO BASED DETECTION OF RALSTONIA SOLANACEARUM Proline Rich Homeodomain (PrhA) an outer membrane bound protein that sense and transfer signal to activate T3SS expression through a linear pathway including the PrhR, PrhI, PrhJ, HrpG and HrpB proteins. So it is among one of the potent bacterial wilt virulence factor and hence can be used as a target for immune based detection
