Figure 1. Biosynthetic gene clusters for 2,4-diacetylphloroglucinol (DAPG) (A), and pyoluteorin (C), the proposed biosynthetic pathways of DAPG (B) and pyoluteorin (D) of P. protegens Pf-5, and the GFP reporter constructs (E, F, G) used in this work.
Arrows represent gene location and orientation in the biosynthetic gene clusters, and are colored according to their functions. The open arrow in (E) indicates that pltR is not included in the pL-gfp construct.
