Abstract 

Bacteria and plant derived volatile organic compounds have been reported as the chemical triggers that elicit induced resistance in plants. Previously, volatile organic compounds (VOCs), including acetoin and 2, 3-butanediol, were found to be emitted from plant growth-promoting rhizobacteria (PGPR) Bacillus subtilis GB03, which had been shown to elicit ISR and plant growth promotion. More recently, we reported data that stronger induced resistance could be elicited against Pseudomonas syringae pv maculicola ES4326 in plants exposed to C13 VOC from another PGPR Paenibacillus polymyxa E681 compared with that of strain GB03. Here, we assessed whether another long hydrocarbon C16 hexadecane (HD) conferred protection to Arabidopsis from infection of a biotrophic pathogen, P. syringae pv maculicola and a necrotrophic pathogen, Pectobacterium carotovorum subsp carotovorum. Collectively, long-chain VOCs can be linked to a plant resistance activator for protecting plants against both biotrophic and necrotrophic pathogens at the same time.
