“…The negative correlation between P N and SQTs suggests that the increased SQT emission from B. nana was not from de novo synthesis but from stored compounds. Thus, the increased emissions of SQTs, typically stored compounds (Duhl et al, 2008), could be related to the higher density of glandular trichomes (Loreto and Schnitzler, 2010;Fineschi et al, 2013) in the snow addition plots. This was supported by the PCA showing a positive correlation between SQT emission and the density of glandular trichomes.…”

“…The study by Kivim€ aenp€ a€ a et al (2016) revealed that higher numbers of terpene-storing structures explained increased terpenoid emissions by warming, elevated O 3 and higher nitrogen availability in Scots pine (Pinus sylvestris), an evergreen conifer. Glandular trichomes, which can be specialized for storage of some BVOCs (Loreto and Schnitzler, 2010;Glas et al, 2012;Fineschi et al, 2013), are reported to decrease with warming (Higuchi et al, 1999) and increase as a function of drought severity (Guerfel et al, 2009), and thus can affect BVOC emissions under climate change. Anatomical changes can develop within weeks, and several studies on environmental change have observed modifications in leaf anatomy of deciduous species already during the first growing season for leaves developed under e.g.…”

Background and Aims Climate change in the Arctic is projected to increase temperature, precipitation and snowfall. This may alter leaf anatomy and gas exchange either directly or indirectly. Our aim was to assess whether increased snow depth and warming modify leaf anatomy and affect biogenic volatile organic compound (BVOC) emissions and CO 2 exchange of the widespread arctic shrubs Betula nana and Empetrum nigrum ssp. hermaphroditum.Methods Measurements were conducted in a full-factorial field experiment in Central West Greenland, with passive summer warming by open-top chambers and snow addition using snow fences. Leaf anatomy was assessed using light microscopy and scanning electron microscopy. BVOC emissions were measured using a dynamic enclosure system and collection of BVOCs into adsorbent cartridges analysed by gas chromatography-mass spectrometry. Carbon dioxide exchange was measured using an infrared gas analyser.Key Results Despite a later snowmelt and reduced photosynthesis for B. nana especially, no apparent delays in the BVOC emissions were observed in response to snow addition. Only a few effects of the treatments were seen for the BVOC emissions, with sesquiterpenes being the most responsive compound group. Snow addition affected leaf anatomy by increasing the glandular trichome density in B. nana and modifying the mesophyll of E. hermaphroditum. The open-top chambers thickened the epidermis of B. nana, while increasing the glandular trichome density and reducing the palisade:spongy mesophyll ratio in E. hermaphroditum.Conclusions Leaf anatomy was modified by both treatments already after the first winter and we suggest links between leaf anatomy, CO 2 exchange and BVOC emissions. While warming is likely to reduce soil moisture, melt water from a deeper snow pack alleviates water stress in the early growing season. The study emphasizes the ecological importance of changes in winter precipitation in the Arctic, which can interact with climate-warming effects.

“…During evolution, plants have evolved various defense strategies, including release of volatile organic compounds (VOCs) from their above-ground organs (Zhang et al, 1999; Zhang and Schlyter, 2004; Huang et al, 2012; Fineschi et al, 2013) into the ambient atmosphere, and even from roots into the soil air space and water (Hiltpold et al, 2011; Turlings et al, 2012). Numerous VOCs have been described, which nevertheless belong to a few broad compound classes, including volatile isoprenoids, volatile products of shikimic acid pathway (phenylpropanoids, benzenoids, indole), carbohydrate and fatty acid cleavage products ( Figure 1 for some examples of characteristic volatiles released from plants and Figure 2 for their biosynthetic pathways (Knudsen et al, 1993; Dudareva et al, 2006; Qualley and Dudareva, 2008; Dicke and Baldwin, 2010; Fineschi et al, 2013). In a few cases, specialized volatiles such as sulfur-containing glucosinolate cleavage products in Brassicales and Malpighiales and furanocoumarins and their derivatives in Apiales, Asterales, Fabales, Rosales, and Sapindales are produced (Berenbaum and Zangerl, 2008; Agrawal, 2011).…”

“…Independent of the way of emission, airborne volatiles are thought to be involved in defense reactions elicited by herbivores, pathogens, and even against abiotic stress factors (Dicke and Baldwin, 2010; Fineschi et al, 2013; Possell and Loreto, 2013). These defense responses can be either direct or indirect.…”

Plants have to cope with a plethora of biotic stresses such as herbivory and pathogen attacks throughout their life cycle. The biotic stresses typically trigger rapid emissions of volatile products of lipoxygenase (LOX) pathway (LOX products: various C6 aldehydes, alcohols, and derivatives, also called green leaf volatiles) associated with oxidative burst. Further a variety of defense pathways is activated, leading to induction of synthesis and emission of a complex blend of volatiles, often including methyl salicylate, indole, mono-, homo-, and sesquiterpenes. The airborne volatiles are involved in systemic responses leading to elicitation of emissions from non-damaged plant parts. For several abiotic stresses, it has been demonstrated that volatile emissions are quantitatively related to the stress dose. The biotic impacts under natural conditions vary in severity from mild to severe, but it is unclear whether volatile emissions also scale with the severity of biotic stresses in a dose-dependent manner. Furthermore, biotic impacts are typically recurrent, but it is poorly understood how direct stress-triggered and systemic emission responses are silenced during periods intervening sequential stress events. Here we review the information on induced emissions elicited in response to biotic attacks, and argue that biotic stress severity vs. emission rate relationships should follow principally the same dose–response relationships as previously demonstrated for different abiotic stresses. Analysis of several case studies investigating the elicitation of emissions in response to chewing herbivores, aphids, rust fungi, powdery mildew, and Botrytis, suggests that induced emissions do respond to stress severity in dose-dependent manner. Bi-phasic emission kinetics of several induced volatiles have been demonstrated in these experiments, suggesting that next to immediate stress-triggered emissions, biotic stress elicited emissions typically have a secondary induction response, possibly reflecting a systemic response. The dose–response relationships can also vary in dependence on plant genotype, herbivore feeding behavior, and plant pre-stress physiological status. Overall, the evidence suggests that there are quantitative relationships between the biotic stress severity and induced volatile emissions. These relationships constitute an encouraging platform to develop quantitative plant stress response models.

“…Isoprene is estimated to comprise approximately 50 of the annual global emission of BVOC Fuentes et al, 2000 . Terpenoids are highly reactive with ozone and hydroxyl radicals as compared to most anthropogenic volatile organic compounds, therefore, terpenoids contribute to the formation of ozone and other photochemical oxidants in the lower regions of the atmosphere Peñuelas and Staudt, 2010;Kim et al, 2015 . Furthermore, BVOC also play important roles in ecological communities and plant development in natural ecosystems Fineschi et al, 2013 . The review of Kesselmeier and Staudt 1999 on BVOC emitted from plant leaves revealed that some species emit only isoprene or monoterpenes, while some other species emit both isoprene and monoterpenes.…”

Recently, Moso bamboo forests have been expanding in Japan because they were left unmanaged and because of the characteristically fast growth rate of bamboo. In this study, trees of 14 bamboo species in two bamboo forests and an exhibition garden in Japan were screened for biogenic volatile organic compound BVOC emissions by using a leaf cuvette. The screening showed that 12 out of 14 species 86 emitted isoprene at rates of 0.7 99.1 nmol m 2 s 1 .No monoterpene and sesquiterpene emitters were identified. Our result indicated that several bamboo species, such as Phyllostachys spp., Semiarundinaria spp., and Bambusa spp., should be categorized as strong isoprene emitters. We also measured the diurnal patterns of isoprene emissions for Phyllostachys heterocycla and Phyllostachys bambusoides in spring and summer, 2015. The isoprene emission rates of both species increased on summer days, reaching a maximum level 78.1 nmol m 2 s 1 and 57.6 nmol m 2 s 1 , respectively around noon, and were lower in spring <5 nmol m 2 s 1 .Our results indicate that the increasing areas of bamboo forest in future could contribute to increasing atmospheric concentrations of ozone and other photochemical oxidants.
