The CI assays carried out in bean allows us to classify Pph 1448a effectors into three groups: group I effectors, including those individually required for wild type-like growth throughout the course of the infection (AvrB2, HopAB1, HopI1, and HopR1); group II effectors, including those individually necessary for growth at later stages of the infection (HopAS1 and HopAU1); and group III including effectors and/or helper proteins not individually necessary for growth within bean leaves (AvrD1, HopAE1, HopAY1, HopAW1, HopD1, HopAJ1, HopAK1, HopG1 and HopQ1). The gene discussed is ENO1; the disease is infection.
