“…In return, microbes may receive nutrients and better protected ecological niche. Recently, a number of studies suggested the role of microbial VCs in improving plant’s ability to manage different types of stress, including drought, salinity and pathogen infection (Ortíz-Castro et al 2009; Bailly and Weisskopf 2012; Bitas et al 2013; Farag et al 2013; Kanchiswamy et al 2015; Chung et al 2016; Li et al 2016; Piechulla et al 2017). Here, we showed that VCs produced by soilborne fungal pathogens F. oxysporum and V. dahliae also help A. thaliana growth better in the presence of salt.…”

Volatile compounds (VCs) produced by diverse microbes seem to affect plant growth, development and/or stress tolerance. We investigated how VCs released by soilborne fungi Fusarium oxysporum and Verticillium dahliae affect Arabidopsis thaliana responses to abiotic and biotic stresses. Under salt stress, VCs from both fungi helped its growth and increased chlorophyll content. However, in contrast to wild-type A. thaliana (Col-0), V. dahliae VCs failed to increase leaf surface area in auxin signalling mutants aux1-7, tir1-1 and axr1-3. Compared to wild-type Col-0, the degree of lateral root density enhanced by V. dahliae VCs in these mutants was also reduced. Consistent with the involvement of auxin signalling in fungal VC-mediated salt torelance, A. thaliana line carrying DR5::GUS displayed increased auxin accumulation in root apex upon exposure to V. dahliae VCs, and 1-naphthylphthalamic acid, an auxin transport inhibitor, adversely affected V. dahliae VC-mediated salt tolerance. F. oxysporum VCs induced the expression of PR1 but not PDF1.2 in A. thaliana lines containing PR1::GUS and PFD1.2::GUS. When challenged with Pseudomonas syringae after the exposure to F. oxysporum VCs, A. thaliana showed reduced disease symptoms. However, the number of bacterial cells in F. oxysporum VC-treated plants was not significantly different from that in control plants.

“…ketones). In the last decade, VOCs emitted by species belonging to Bacillus genus have been described for their ability to induce growth in Arabidopsis thaliana, which is usually used as model plant (Ryu et al, 2003;Kanchiswamy et al, 2015). The VOCs have the ability to elicit plant growth in absence of physical contact through the induction of physiological changes depending on doses and culture medium for bacterial growth (Zhang et al, 2007;Blom et al, 2011).…”

Volatile organic compounds (VOCs) emitted by Bacillus species have been reported as growth inducers in Arabidopsis thaliana, but their effects on horticultural species have been scarcely studied. In this study, Lactuca had a greater effect. It noteworthy that root development was higher when BCT9 was grown in MRVP-A than in the others culture medium. The identified VOCs released by BCT9 in MRVP-A were 3-hydroxy-2-butanone, 2,3-butanediol, 2-nonanone, 2-undecanone, 2-tridecanone and 2-pentadecanone. Furthermore, the toxicity bioassays indicated that most VOCs did not have high toxic effects and some VOCs stimulated the growth at seed germination stage. In conclusion, this study suggests that VOCs can strongly modulate the L. sativa growth during germination and seedlings stages, so new explorations should be carried out in other vegetables to determine their effects.

“…Bacterial and fungal VOCs, including terpenes, may represent an alternative to harmful pesticides, fungicides, and bactericides and thus might be the future to protect plants from pathogens and provide a setting for better crop welfare. Research in the last 10 years has led to an increasingly clear understanding of the role of VOCs as biocontrol agents to control various phytopathogens and as biofertilizers for plant growth promotion (Kanchiswamy et al, 2015). Yet, the application of microbial VOCs in agriculture is still in its infancy.…”
