This is the first report of the production of these assumed fermentation products by a pseudomonad and the role of the sensor kinase GacS in production of 2R, 3R-butanediol.
2R,3R-butanediol, a bacterial volatile produced by Pseudomonas chlororaphis O6, is involved in induction of systemic tolerance to drought in Arabidopsis thaliana.

It is concluded that the bacterial volatile 2R,3R-butanediol was a major determinant in inducing resistance to drought in Arabidopsis through an SA-dependent mechanism.
Cloning and Expression of Pyrroloquinoline Quinone (PQQ) Genes from a Phosphate-Solubilizing Bacterium Enterobacter intermedium
- Chul-Hong Kim, S. Han, Young Cheol Kim

It is speculated that production of PQQ in E. coli DH5α expressing the pqq cluster activates an endogenous glucose dehydrogenase to permit gluconic acid secretion that solubilizes the insoluble phosphate.

The findings suggest that PQQ plays an important function in beneficial traits including phosphate solubilization, antifungal activity, and induced systemic resistance of E. intermedium, possibly by acting as a cofactor for several enzymes including glucose dehydrogenase.
The RpoS Sigma Factor Negatively Regulates Production of IAA and Siderophore in a Biocontrol Rhizobacterium, Pseudomonas chlororaphis O6
- Sang-Ah Oh, Ji Soo Kim, Young Cheol Kim
- BiologyPlant Pathology Journal
- 1 September 2013
Taken together, RpoS exerted regulatory control over factors important for the habitat of P. chlororaphis O6 in soil and on root surfaces and altered isozyme patterns for peroxidase, catalase and superoxide dismutase ensured protection against oxidative stress and sensitivity to hydrogen peroxide exposure.
Draft Genome Sequence of the Biocontrol Bacterium Pseudomonas putida B001, an Oligotrophic Bacterium That Induces Systemic Resistance to Plant Diseases

- 9 November 2011
Comparison of this sequence to the sequenced genome of P. putida KT2440 points to a subset of gene functions that may be related to the defense-inducing functions of strain B001.
Multiple determinants influence root colonization and induction of induced systemic resistance by Pseudomonas chlororaphis O6.

It is shown that multiple determinants are involved in the induction of systemic resistance, with there being a requirement for strong root colonization.
Tobacco cultivars vary in induction of systemic resistance against Cucumber mosaic virus and growth promotion by Pseudomonas chlororaphis O6 and its gacS mutant
- C. Ryu, B. Kang, Young Cheol Kim
- BiologyEuropean journal of plant pathology
- 5 June 2007
The results indicate rhizobacteria-elicited induced viral resistance without a negative impact on growth but there was a differential response between cultivars.
