Fig. 1From: Characterization of two SGNH family cell death-inducing proteins from the horticulturally important fungal pathogen Botrytis cinerea based on the optimized prokaryotic expression systemOptimization of the prokaryotic expression system. A Expression of soluble recombinant cell death-inducing proteins (CDIPs) utilizing the optimized prokaryotic expression system. The reported CDIPs BcIEB1 (BCIN_15g00100), BcNEP1 (BCIN_06g06720), BcSPL1 (BCIN_03g00500), and BcXYG1 (BCIN_03g03630) were recombinantly expressed with trigger factor (TF) using the prokaryotic expression system, and the TF was expressed as a control. The supernatant of disrupted cells was used for protein purification. B The impact of TF on plants. TF at different concentrations were infiltrated into tobacco leaves, and 10Â mM phosphate-buffered saline (PBS) was used as the negative control. Photos were taken 5 d after infiltration.
