“…The authors also demonstrated that the antagonists suppressed crown gall formation, resulting in a three-to eight-fold decrease in tumor mass, indicating that this molecule might be involved in the suppression of oncogenicity in tomato seedlings (Dandurishvili et al, 2011) Agrobacterium sp. (Chernin et al, 2013;Popova et al, 2014;Plyuta et al, 2016). The observed effects on the pathogens include reduced biofilm formation, a decrease in the number of living cells composing the biofilm by almost 4-fold and a decreased mycelial growth.…”

“…We previously showed that sometimes, the results obtained with the synthetic volatiles on validation tests are not the same as those with the antagonist strain. For instance, the growth inhibition of Agrobacterium tumefaciens by VOCs from Serratia sp., mainly due to the compound DMDS, was observed by Dandurishvili et al (2011), Chernin et al (2013, Popova et al (2014) and Plyuta et al (2016), but not by Ossowicki et al (2017). Thus, we need to expand our knowledge about which bioactive molecules act individually or in combination and what respective concentrations are necessary to cause inhibition.…”

“…Accordingly, other studies reported the potential inhibitory activity of VOCs produced by different strains of Pseudomonas , as well as Serratia , against Agrobacterium sp. ( Chernin et al, 2013 ; Popova et al, 2014 ; Plyuta et al, 2016 ). The observed effects on the pathogens include reduced biofilm formation, a decrease in the number of living cells composing the biofilm by almost 4-fold and a decreased mycelial growth.…”

Plant diseases caused by phytopathogens result in huge economic losses in agriculture. In addition, the use of chemical products to control such diseases causes many problems to the environment and to human health. However, some bacteria and fungi have a mutualistic relationship with plants in nature, mainly exchanging nutrients and protection. Thus, exploring those beneficial microorganisms has been an interesting and promising alternative for mitigating the use of agrochemicals and, consequently, achieving a more sustainable agriculture. Microorganisms are able to produce and excrete several metabolites, but volatile organic compounds (VOCs) have huge biotechnology potential. Microbial VOCs are small molecules from different chemical classes, such as alkenes, alcohols, ketones, organic acids, terpenes, benzenoids and pyrazines. Interestingly, volatilomes are species-specific and also change according to microbial growth conditions. The interaction of VOCs with other organisms, such as plants, insects, and other bacteria and fungi, can cause a wide range of effects. In this review, we show that a large variety of plant pathogens are inhibited by microbial VOCs with a focus on the in vitro and in vivo inhibition of phytopathogens of greater scientific and economic importance in agriculture, such as Ralstonia solanacearum, Botrytis cinerea, Xanthomonas and Fusarium species. In this scenario, some genera of VOC-producing microorganisms stand out as antagonists, including Bacillus, Pseudomonas, Serratia and Streptomyces. We also highlight the known molecular and physiological mechanisms by which VOCs inhibit the growth of phytopathogens. Microbial VOCs can provoke many changes in these microorganisms, such as vacuolization, fungal hyphal rupture, loss of intracellular components, regulation of metabolism and pathogenicity genes, plus the expression of proteins important in the host response. Furthermore, we demonstrate that there are aspects to investigate by discussing questions that are still not very clear in this research area, especially those that are essential for the future use of such beneficial microorganisms as biocontrol products in field crops. Therefore, we bring to light the great biotechnological potential of VOCs to help make agriculture more sustainable.
