“…Endophytic bacteria spend their life within the plant tissues without leading to development of any disease, and they produce a wide range of volatile organic compounds with an antimicrobial activity 26 . In previous studies, endophytic bacteria were isolated from healthy domesticated and wild-growing grapevine in Iran, and some strains were detected with antagonistic effects on Agrobacterium tumefaciens , which is the causal agent of crown gall disease under both in vitro and in vivo conditions 21 .…”

The volatile organic compounds (VOCs) produced by endophytic bacteria have a significant role in the control of phytopathogens. In this research, the VOCs produced by endophytic bacteria including Serratia sp. Ba10, Pantoea sp. Sa14, Enterobacter sp. Ou80, Pseudomonas sp. Ou22, Pseudomonas sp. Sn48 and Pseudomonas sp. Ba35, which were previously isolated from healthy domesticated and wild-growing grapevine were evaluated in terms of their effects on the virulence traits of Agrobacterium tumefaciens Gh1, the causal agent of crown gall disease. Based on the gas chromatography–mass spectrometry analysis, 16, 15, 14, 7, 16, and 15 VOCs have been identified with high quality in strains of Ba10, Sa14, Ou80, Ou22, Sn48, and Ba35, respectively. All endophytic bacteria produced VOCs that significantly reduced crown gall symptoms and inhibited the populations of A. tumefaciens Gh1 at different levels. Moreover, scanning electron microscopy analysis revealed various morphological abnormalities in the A. tumefaciens cells exposed to the VOCs produced by Ba35, Ou80, and Sn48 strains. The VOCs significantly reduced swarming-, swimming-, twitching motility and biofilm formation by A. tumefaciens Gh1. Our results revealed that VOCs could reduce the attachment of A. tumefaciens Gh1 cells to root tissues of grapevine cultivars Rashe and Bidane sefid, as well as chemotaxis motility towards root extract of both cultivars. Based on our results, it was shown that the antibacterial VOCs produced by endophytic bacteria investigated in the current study can manage crown gall disease and increase our knowledge on the role of VOCs in microbial interactions.

“…It is known that PGPR can alter the plant's VOC signalling (Santoro et al ., 2015; Cappellari et al ., 2017). However, most studies focus on how the emission of microbial VOCs modulates plant development (Chowdhury et al ., 2019), and not on how the plant's VOC profile changes upon microbial inoculation.…”

The beneficial features of Bacillus thuringiensis (Bt) are not limited to its role as an insecticide; it is also able to promote plant growth interacting with plants and other plant growth-promoting rhizobacterium (PGPR). The PGPR Bt strain RZ2MS9 is a multi-trait maize growth promoter. We obtained a stable mutant of RZ2MS9 labelled with green fluorescent protein (RZ2MS9-GFP). We demonstrated that the Bt RZ2MS9-GFP successfully colonizes maize's roots and leaves endophytically. We evaluated whether RZ2MS9 has an additive effect on plant growth promotion when co-inoculated with Azospirillum brasilense Ab-V5. The two strains combined enhanced maize's roots and shoots dry weight around 50% and 80%, respectively, when compared to the noninoculated control. However, non-differences were observed comparing RZ2MS9 alone and when co-inoculated with Ab-V5, In addition, we used co-inoculation experiments in glass chambers to analyse the plant's volatile organic compounds (VOCs) production during the maize-RZ2MS9 and maize-RZ2MS9-Ab-V5 interaction. We found that the single and co-inoculation altered maize's VOCs emission profile, with an increase in the production of indoles in the co-inoculation. Collectively, these results increase our knowledge about the interaction between the Bt and maize, and provide a new possibility of combined application with the commercial inoculant A. brasilense Ab-V5.
