Metabolic pathways and transport systems found in the genome of Pseudomonas
fluorescence DR397. (a) Gene clusters and functional pathway associated with biosynthesis of indole-3-acetic acid (IAA) and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase to control plant ethylene levels. (b) Gene clusters for the biosynthesis and uptake of compatible solutes (amino acids): glycine betaine, choline, proline, glutamate in DR397. (c) Compatible solutes (sugar): glucose, maltose uptake, and Trehalose synthesis. (d) Transport and exchange of nutrients, including ions (sodium, potassium) and hydrogen cyanide biosynthesis hcnABC structural gene clusters in DR397.
