R. solanacearum HpaB interacts with nine type III effectors. (a) Yeast cells were co-transformed by BD-HpaB and 38 AD-T3Es. Double transformation and interactions were tested by plating yeasts on synthetic dropout medium lacking leucine and tryptophan (SD/–Leu/–Trp) and synthetic dropout medium lacking leucine, tryptophan and histidine (SD/–Leu/–Trp/–His), respectively. RipW and RipG7 have the same profile as 26 other T3Es tested. BD-p53 and AD-T-antigen were used as negative controls. Three biological replicates were performed and gave same results. (b) Glutathione S-transferase (GST) and GST-T3Es were immobilized on glutathione sepharose and incubated with an E. coli lysate containing 6His-HpaB. Total cell lysates and eluted proteins were analyzed using antibodies directed against GST and the 6His epitope. Bands corresponding to GST and GST fusion proteins are marked by asterisks; lower bands represent degradation products. For lack of space, samples have been loaded into two gels (black line separation). The experiments have been repeated twice with similar results.
