“…Aboveground, VOCs emitted by damaged plant parts can prime or induce direct/indirect defence mechanisms in yet undamaged parts of the same plant (Das et al 2013). Both VOCs emitted at the site of attack and chemical signals (e.g., plant hormones) travelling inside the vascular tissues of the attacked plant mediate interactions between damaged and undamaged plant parts (Erb et al 2008;Das et al 2013).…”

“…Both VOCs emitted at the site of attack and chemical signals (e.g., plant hormones) travelling inside the vascular tissues of the attacked plant mediate interactions between damaged and undamaged plant parts (Erb et al 2008;Das et al 2013). Given that the roots of plants attacked by insect herbivores also synthesise and release VOCs in the soil (Table 1), their roles in mediating interactions between the roots and shoots of the same plant are worth investigating (Fig.…”

Root-emitted volatile organic compounds: can they mediate belowground plant-plant interactions?

Background Aboveground, plants release volatile organic compounds (VOCs) that act as chemical signals between neighbouring plants. It is now well documented that VOCs emitted by the roots in the plant rhizosphere also play important ecological roles in the soil ecosystem, notably in plant defence because they are involved in interactions between plants, phytophagous pests and organisms of the third trophic level. The roles played by root-emitted VOCs in between-and withinplant signalling, however, are still poorly documented in the scientific literature. Scope Given that (1) plants release volatile cues mediating plant-plant interactions aboveground, (2) roots can detect the chemical signals originating from their neighbours, and (3) roots release VOCs involved in biotic interactions belowground, the aim of this paper is to discuss the roles of VOCs in between-and withinplant signalling belowground. We also highlight the technical challenges associated with the analysis of root-emitted VOCs and the design of experiments targeting volatile-mediated root-root interactions. Conclusions We conclude that root-root interactions mediated by volatile cues deserve more research attention and that both the analytical tools and methods developed to study the ecological roles played by VOCs in interplant signalling aboveground can be adapted to focus on the roles played by root-emitted VOCs in between-and within-plant signalling.

“…Herbivore-induced plant volatiles serve as external signals for within-plant communication, and elicit a defence response in systemic parts of the affected plant (Karban et al, 2006;Frost et al, 2007;Heil and Silva Bueno, 2007;Park et al, 2007;Das et al, 2013). Damaged leaves immediately release VOCs and communicate more quickly with leaves located nearby that are not directly connected by vasculature (Heil and Ton, 2008).…”

Background Plants, though sessile, employ various strategies to defend themselves against herbivorous insects and convey signals of an impending herbivore attack to other plant(s). Strategies include the production of volatiles that include terpenoids and the formation of symbiotic associations with fungi, such as arbuscular mycorrhiza (AM). This constitutes a two-pronged above-ground/below-ground attack-defence strategy against insect herbivores.Scope Terpenoids represent an important constituent of herbivore-induced plant volatiles that deter herbivores and/or attract their predators. Terpenoids serve as airborne signals that can induce defence responses in systemic undamaged parts of the plant and also prime defence responses in neighbouring plants. Colonization of roots by AM fungi is known to influence secondary metabolism in plants; this includes alteration of the concentration and composition of terpenoids, which can boost both direct and indirect plant defence against herbivorous insects. Enhanced nutrient uptake facilitated by AM, changes in plant morphology and physiology and increased transcription levels of certain genes involved in the terpenoid biosynthesis pathway result in alterations in plant terpenoid profiles. The common mycorrhizal networks of external hyphae have added a dimension to the two-pronged plant defence strategy. These act as conduits to transfer defence signals and terpenoids.Conclusion Improved understanding of the roles of terpenoids in plant and AM defences against herbivory and of interplant signalling in natural communities has significant implications for sustainable management of pests in agricultural ecosystems.

“…This finding revealed that one or some VOCs directly or indirectly influenced the photosynthesis of tobacco by affecting the conduction and transport of CO 2 , reduction reaction and electron transfer, leading to the impaired growth and development of tobacco. Many studies have shown that plants may carry out ''exchange of information'' through some volatiles (Das et al 2013), and these volatiles may act as allelochemicals to affect the plant growth and resistance (Karban et al 2006). However, most of results about this study came from laboratory bioassay.…”

Volatile organic compounds (VOCs) play an important role in plant communication. Rose floral scent consists of many VOCs, such as aroma alcohols, esters and terpenes. It remains unclear if floral scent from rose can affect the growth of tobacco. In order to explore the tobacco response induced by rose floral scent, we performed the proteomic analysis on tobacco leaves influenced by floral scent from rose using two-dimensional electrophoresis. Protein profiles revealed that 470 ± 37 and 319 ± 18 protein spots were detected in sole tobacco and tobacco/rose intercropping samples, respectively. Compared with those of sole tobacco samples, 26 protein spots exhibited at least twofold change at the protein level, including six up-regulated and 20 down-regulated proteins. In addition, 20 proteins were identified by MALDI-TOF/ OF MS analysis and database searches, and results showed that they were involved in the defense response, photosynthesis, protein catabolic process, regulation of stomata movement and electron transport.
