“…Thus, 2-nonanone and 2-decanone particularly showed a specific strong inhibition activity against Fusarium oxysporum (Yuan et al 2012;Raza et al 2015). Conversely, 2-tetradecanone and 2-pentadecanone, even though they were abundant at least based on the large peaks areas that can be observed in the GC chromatographs, are known to be poor inhibitors of fungal growth (Yuan et al 2012;Li et al 2014). Therefore, according to these results 2-nonanone, 2-undecanone and 2-tridecanone that were synthetized by B. subtilis Er/S were responsible for reducing mycelial growth of pathogens and also inhibit spore germination (Yuan et al 2012).…”

The endophytic microbiome uses mechanisms such as the secretion of diffusible antibiotic molecules, synthesis and release of volatile organic compounds, and/or toxins to protect plants. The aim of this research was to study the volatile organic compounds (VOCs) profile as well as the diffusible secondary metabolites produced and released by endophytic bacteria isolated from tomato plants that in in-vitro assays prevented growth of pathogenic fungi. Bacteria belonging to seven genera (Acinetobacter, Arthrobacter, Bacillus, Microbacterium, Pantoea, Pseudomonas, and Stenotrophomonas) were isolated from different tissues of tomato plants with and without symptoms of Gray leaf spot, a disease provoked by Stemphylium lycopersici. In vitro, antagonistic assays were performed and the effect of volatile and soluble compounds released by endophytic bacteria on the growth of pathogenic fungi was determined. The VOCs synthesized by the endophytes were extracted, identified and quantified. These isolates representatives of seven bacterial genera inhibited the growth of three fungal pathogens of tomato S. lycopersici, Alternaria alternata and Corynespora cassiicola, which was related to the synthesis of soluble compounds as well as VOCs. Endophytes synthesize and release different VOCs, probably due to the different type of interaction that each bacterium establishes with the fungus, presenting a range of fungal growth inhibition.

“…Red crosses indicate deleted genes; red arrow indicates engineered genes; Blue genes and arrows remarked exogenous components for metabolite engineering. The pathway was modified from previous publications (Li et al 2013;Li et al 2014;Xu et al 2014) slaC budB and budA Engineering plant-associated bacteria to boost production of 2,3-butanediol Certain Gram-negative and -positive bacteria and PGPR species produce 2,3-butenadiol but do not reach the functional levels required for beneficial action in the plants. The goal of the studies is to improve 2,3-butanediol production in species with low levels by introducing exogenous genes for overexpression studies.…”

Sweet scents from good bacteria: Case studies on bacterial volatile compounds for plant growth and immunity

Beneficial bacteria produce diverse chemical compounds that affect the behavior of other organisms including plants. Bacterial volatile compounds (BVCs) contribute to triggering plant immunity and promoting plant growth. Previous studies investigated changes in plant physiology caused by in vitro application of the identified volatile compounds or the BVC-emitting bacteria. This review collates new information on BVC-mediated plant-bacteria airborne interactions, addresses unresolved questions about the biological relevance of BVCs, and summarizes data on recently identified BVCs that improve plant growth or protection. Recent explorations of bacterial metabolic engineering to alter BVC production using heterologous or endogenous genes are introduced. Molecular genetic approaches can expand the BVC repertoire of beneficial bacteria to target additional beneficial effects, or simply boost the production level of naturally occurring BVCs. The effects of direct BVC application in soil are reviewed and evaluated for potential large-scale field and agricultural applications. Our review of recent BVC data indicates that BVCs have great potential to serve as effective biostimulants and bioprotectants even under open-field conditions.
