Proteomes of Mycoplasma gallisepticum strains with overexpression and knockdown of WhiA transcription factor. The overexpression was introduced on a transposon vector carrying M. gallisepticum whiA gene with strong constitutive promoter and strong SD sequence. The knockdown was made by CRISPRi. dCas9 protein and sgRNA against whiA gene were introduced on a transposon vector.
