Figure 7From: Genetic dissection of the polyoxin building block-carbamoylpolyoxamic acid biosynthesis revealing the “pathway redundancy” in metabolic networksTime-course bioassay and transcriptional analysis of S. cacaoi CY21 strain ( argB mutant). (A) Time-course bioassay for CY21 and WT strains of S. cacaoi; (B) Time-course transcriptional analysis of S.cacaoi CY21 strain, and RT-PCR was used for time-course transcriptional analysis of CY21 strain. “W” indicates wild type of S. cacaoi, and “M” means CY21 mutant of S. cacaoi. The methods for the time-course bioassay and time-course transcriptional analysis of S. cacaoi CY21 strain were described in Additional file 1.Back to article page
