Abstract

A toxin complex consists of a high-molecular-weight group of toxins that exhibits insecticidal activity against insect pests. These toxins are a promising alternative to () toxins that have been extensively utilized in insect pest control. Herein, a codon-optimized insecticidal gene () (381 bp) identified in strain MHSD5 (a bacterial endophyte previously isolated from ) was ligated into the pET SUMO expression vector and expressed in BL21 (DE3). We report the success of cloning the gene into the pET SUMO vector and ultimately the transformation into BL21 (DE3) competent cells. However, despite conducting a time course of expression as well as isopropyl β-d-1-thiogalactopyranoside (IPTG) dosage optimization to determine optimal conditions for expression, TccZ protein expression could not be detected on Stain-Free and Coomassie-stained SDS-PAGE gels.
