“…However, some FVOCs emitted by pathogenic fungi are classified as phytotoxins negatively affecting plant growth, for instance: 1-octen-3-ol, trans -2-octenal, 1-hexanol, 3-octanone, 3-methyl-1-butanol and 2-phenylethanol ( Werner et al., 2016 ). The compounds 1-octen-3-ol and trans -2-octenal inhibit root and cotyledon leaf growth, and induce bleaching of the seedlings in A. thaliana by H 2 O 2 production ( Ferreira et al., 2023 ; Wang et al., 2023 ). Another example of FVOCs with negative effects on plants are those emitted by Fusarium culmorum and Cochliobolus sativus , which modify the emission of barley VOCs from roots during their interaction, affecting the possibility to prime neighborhood plants.…”

Microbial volatile organic compounds (MVOCs) are mixtures of gas-phase hydrophobic carbon-based molecules produced by microorganisms such as bacteria and fungi. They can act as airborne signals sensed by plants being crucial players in triggering signaling cascades influencing their secondary metabolism, development, and growth. The role of fungal volatile organic compounds (FVOCs) from beneficial or detrimental species to influence the physiology and priming effect of plants has been well studied. However, the plants mechanisms to discern between FVOCs from friend or foe remains significantly understudied. Under this outlook, we present an overview of the VOCs produced by plant-associate fungal species, with a particular focus on the challenges faced in VOCs research: i) understanding how plants could perceive FVOCs, ii) investigating the differential responses of plants to VOCs from beneficial or detrimental fungal strains, and finally, iii) exploring practical aspects related to the collection of VOCs and their eco-friendly application in agriculture.

Pelgipeptins, tridecaptins, and elgicins are among the antimicrobials produced by Paenibacillus elgii. Growth in complex media is commonly applied to obtain lipopeptides from culture's supernatant, but it requires further purification. This study aimed to improve the yield of pelgipeptins and tridecaptins using chemically defined media. The kinetics of antimicrobial lipopeptide yield in chemically defined media was evaluated in P. elgii AC13. Pelgipeptins were detected in the supernatant and the culture pellet, but tridecaptins were mainly associated with cell debris or endospores. We investigated whether removing Ca2+ would impair P. elgii sporogenesis, consequently improving the yield of tridecaptin. The kinetics of both lipopeptides in the presence and absence of Ca2+ were quantitatively and qualitatively evaluated and further correlated with the cell cycle. The impairment of P elgii AC13 sporogenesis had no effect on tridecaptin production, which remained undetected in the supernatant of the culture. On the other hand, the yield of pelgipeptin in a Ca2+-free medium increased. We showed for the first time that the removal of Ca2+ interrupted the sporogenesis in P. elgii and improved the yield of pelgipeptins. However, Ca+2 absence had no effect on tridecaptin yield, which is possibly degraded or associated with other cell debris component.
