Identification and definition of a Bro1 domain proteins associated with sophorolipids synthesis in Starmerella bombicola

The goals of this study are to compare different gene expressions for starmerella bombicola Bro1,gme3597 and gme3787 knockout strain, the reference strain wild-type was considered as a control. The deletion of Bro1 significantly downregulated genes involved in the sophorolipids synthesis-related pathwaw and resulted in the inability of the mutant to synthesize sophorolipids. The deletion of gme3696 also down-regulated the expression of sophorolipid synthesis-related genes. The knockout of gme3787 up-regulated the expression of UDP-glucose pyrophosphorylase.This study provides the information that Bro1 function are required in sophorolipids synthesis of starmerella bombicola. Overall design: A total of 12 samples were analzyed, which include biological triplicates. The reference strain wild-type was considered as a control.
