“…The volatile profile of tomato leaves of the cultivars Aromata, Santa Clara, and Carmen was dominated by monoterpenes, in particular β-phellandrene (major compound), limonene, and 2-carene, and the sesquiterpene (E)-β-caryophyllene (Table 1), which is in accordance with headspace analysis of other tomato cultivars (Buttery et al, 1987;Zhang et al, 2008). Nonetheless, overall headspace composition of Aromata differed significantly from Santa Clara and Carmen (Fig.…”

The tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae) is a devastating pest of cultivated tomato Solanum lycopersicum throughout South and Central America and Europe. We aimed to characterize the behavioral mechanisms and the chemical cues involved in host selection of T. absoluta females by chemical analysis of tomato leaf volatiles, wind tunnel attraction assays, and oviposition bioassays. Tomato leaf odor elicited in mated females upwind orientation flight followed by landing as well as egg-laying, demonstrating the essential role of plant volatiles in T. absoluta host-finding behavior. In wind tunnel and oviposition choice experiments, T. absoluta females significantly preferred tomato S. lycopersicum over wild tomato Solanum habrochaites, which is resistant to larval feeding. This indicates that leaf volatiles provide information on the suitability of plants as larval hosts. Mated females also discriminated three cultivars of S. lycopersicum according to their volatile profiles. Headspace collections from leaves of these three cultivars contained large amounts of β-phellandrene, followed by limonene, 2-carene, and (E)-β-caryophyllene, which together accounted for more than 70% of tomato foliage headspace. Most leaf volatiles were released by all three cultivars, but they showed significant differences with respect to the presence of a few minor compounds and blend proportion. This is an initial study of the volatile signatures that mediate attraction and oviposition of tomato leafminer T. absoluta in response to its main host, tomato.

“…The inhibitory effects of volatiles on pathogen growth were evaluated as described by Hamilton-Kemp et al (1992) and Zhang et al (2008). Single drops of B. cinerea or F. oxysporum spore suspensions were added to a 1.0-cm 3 block of 1.2% water agar, which was then placed in a 5-cmdiameter glass Petri dish.…”

“…The procedure for VOC collection was based on methods described by Zhang et al (2008). All leaf samples (5.0 g) were pulverized in liquid nitrogen with a chilled pestle, and the resulting slurry was quickly transferred to a 500-ml Purge-and-Trap apparatus.…”

“…Over time, however, such tomato leaves become more susceptible to disease. Zhang et al (2008) have reported that both the production of volatile compounds and their inhibitory activity increase as tomato plants mature. Chitosan oligosaccharide, which is produced by the degradation of the chemical chitin, can enhance the formation of those volatile compounds and decrease plant susceptibility to B. cinerea (He et al, 2005b).…”

We investigated variations in the level and composition of volatiles emitted by tomato leaves at different ages. Our focus also included their antifungal properties and responses to chitosan oligosaccharide. Based on leaf position, the release of volatiles decreased over time. Young leaves produced high levels of C6-aldehyde, which is mainly composed of hexenal, while the volatiles emitted by more mature leaves largely comprised terpenes, particularly β-phellandrene and caryophyllane. In young upper leaves, the main components (up to 86% of the total) were hexenal, β-phellandrene, and caryophyllane. Their levels decreased steadily over time, from 386.3 μg g −1 fresh weight (FW) in young leaves to 113.2 μg g −1 FW in old tissues. Volatiles emitted from young leaves exhibited the best antifungal activity against spore germination and hyphal growth by Botrytis cinerea and Fusarium oxysporum. Leaves became more susceptible to oligosaccharide treatment with increasing age. When young tissues were exposed to chitosan, we found declines in both the quantity of volatiles and their ability to inhibit fungal growth. Compared with the control, the amount of volatiles from young tissues was 88.4% lower after such treatment. In contrast, contents of volatiles from old and adult leaves were dramatically increased by chitosan oligosaccharide. Likewise, their inhibitory effect was significantly enhanced. Therefore, our results suggest that these volatiles are responsible for antifungal activity and may play a role in age-related resistance by tomato.

“…Tomato is a constitutive emitter of low amounts of mono- and sesquiterpenes under non-stressed conditions, but these emissions become greatly enhanced under stress (Jansen et al 2009; Maes and Debergh 2003). The volatile blends from Solanum lycopersicum leaves detected with SPME GC–MS were mainly terpenoids (i.e., α-Phellandrene), fatty acid derivatives (i.e., Nonanal) and aromatic compounds (Zhang et al 2008). …”

Anti-fungal activity, mechanism studies on α-Phellandrene and Nonanal against Penicillium cyclopium

BackgroundEssential oils from plants have been reported to have wide spread antimicrobial activity against various bacterial and fungal pathogens, and these include α-Phellandrene, Nonanal and other volatile substances. However, biological activities of α-Phellandrene and Nonanal have been reported only in a few publications. Further investigations are necessary to determine the antimicrobial activity of these compounds, especially for individual application, to establish the possible mechanism of action of the most active compound.ResultsThe results are shown that α-Phellandrene and Nonanal have a dose-dependent inhibition on the mycelial growth of Penicillium cyclopium. The minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) are 1.7 and 1.8 mL/L for α-Phellandrene, 0.3 and 0.4 mL/L for Nonanal, respectively. The volatile compounds altered the morphology of P. cyclopium hyphae by causing loss of cytoplasmic material and distortion of the mycelia. The membrane permeability of P. cyclopium increased with increasing concentrations of the two volatile compounds, as evidenced by cell constituent release, extracellular conductivity and induced efflux of K+. Moreover, the two volatile compounds induced a decrease in pH and in the total lipid content of P. cyclopium, which suggested that cell membrane integrity had been compromised.ConclusionsThe results demonstrated that α-Phellandrene and Nonanal could significantly inhibit the mycelia growth of P. cyclopium by severely disrupting the integrity of the fungal cell membrane, leading to the leakage of cell constituents and potassium ions, and triggering an increase of the total lipid content, extracellular pH and membrane permeability. Our present study suggests that α-Phellandrene and Nonanal might be a biological fungicide for the control of P. cyclopium in postharvest tomato fruits.
