“…A variety of factors, such as pathogen attack, exposure to UV light, herbivory, wounding and exposure to elicitor molecules can induce hypersensitive cell death [Doke et al, 1994], and thus could lead to an enhanced volatilization of BCAR from storage pools. Some of these factors, e.g., herbivory [Kessler and Baldwin, 2001;Turlings et al, 1998;Rodriguez-Saona et al, 2001], ozone exposure [Heiden et al, 1999] and the treatment with the elicitor methyl jasmonate [Rodriguez-Saona et al, 2001] have been found to induce the emission of BCAR and/or other sesquiterpenes from leaves on a timescale of hours or days. Anyway, the increased emission could be attributed to both cell lesions and induced sesquiterpene synthesis.…”

“…Leaves of several deciduous forest trees (Betula pendula, B. pubescens, Populus tremula and Sambucus nigra [Zhang et al, 1999]; Carpinus betulus [König et al, 1995]) emit considerable amounts of this reactive volatile hydrocarbon. Moreover, BCAR has been reported to be one of the main components of constitutive or induced terpenoid emissions from foliage of a variety of agricultural plant species, e.g., Prunus avium, Vitis vinifera, Olea europea, Prunus persica [Arey et al, 1991], Citrus sinensis [Hansen and Seufert, 1999], potato plants [Agelopoulos et al, 2000], and leaves of tobacco [Heiden et al, 1999], sunflower [Schuh et al, 1997], maize [Turlings et al, 1998] and cotton [Rodriguez-Saona et al, 2001].…”

[1] Assessments of the overall release of reactive volatile organic compounds from vegetation require the knowledge of the effect of temperature and light intensity on emission rates. The aim of the study presented here was to investigate whether the rates of emission of the highly reactive sesquiterpene b-Caryophyllene (BCAR) from foliage of orange trees (Citrus sinensis (L.) OSBECK, var. Navel and Navel Late), detected using branch enclosures in an orange orchard in Spain, were not only temperature but also light dependent. We used two algorithms to calculate the diurnal variation of BCAR emission rates from environmental data. One algorithm accounted exclusively for the known exponential relationship between emission rate and temperature, and the other for both temperature and light effects. Assuming a light and temperature dependence of BCAR emission rates led to a more precise prediction of the short-term variation of BCAR emission rates than assuming that emissions are affected exclusively by temperature. The light dependence of BCAR emission rates could be due to a modulation of BCAR synthesis by light, or to an enhanced volatilization of BCAR from storage pools under high light exposure, or a combination of both. The data show that present assessments of the total release of reactive volatile organic compounds from vegetation, disregarding light effects on BCAR emission, are highly uncertain, if BCAR considerably contributes to total terpenoid emissions of the investigated plants.

“…Ozone-resistant and susceptible tobacco (Nicotiana tabacum) plants have different temporal patterns of VOC (sesquiterpene) production in response to exposure to ozone. Ozone-resistant tobacco produces sesquiterpenes immediately after exposure while ozone-susceptible tobacco does not (Heiden et al, 1999). Work with A. thaliana suggests a relationship between ozone resistance and the production of VOCs that quench ozone (Holopainen, 2004;Dudareva et al, 2006).…”

Learned and naïve natural enemy responses and the interpretation of volatile organic compounds as cues or signals

SummaryIn response to arthropod herbivory, plants release volatile organic compounds (VOCs), which are attractive to natural enemies. Consequently, VOCs have been interpreted as co-evolved plant-natural enemy signals. This review argues that, while these data are necessary, they are not sufficient to demonstrate a VOC plant-natural enemy signaling function. We propose that evidence that (1) plant fitness is increased as a consequence of natural enemy recruitment, and either (2A) natural enemies preferentially learn prey-induced VOCs or (2B) natural enemies respond innately to the VOCs of the prey-host plant complex, is also required. Whereas there are too few studies to rigorously test hypotheses 1 and 2A, numerous studies are available to test hypothesis 2B. Of 293 tests of natural enemy responses to VOCs, we identified only 74 that were unambiguous tests of naïve natural enemies; in the remainder of the tests either natural enemies were experienced with their host in the presence of VOCs, or experience could not be ruled out. Of those 74 tests with naïve natural enemies, attraction was observed in 41 and not in 33. This review demonstrates that empirical support for the hypothesized VOC plant-natural enemy signaling function is not universal and presents alternative hypotheses for VOC production.

“…Recent work provides evidence that VOC may be involved in protection against oxidizing agents like ozone (Zeidler et al, 1997;Loreto et al, 2001;Penuelas & Llusia, 2001). The influence of elevated atmospheric ozone on the emission capacity of plants, as an abiotic stress factor, is currently under debate (Kimmerer & Kozlowski, 1982;Heiden et al, 1999Heiden et al, , 2003Llusia et al, 2002;Wildt et al, 2003), and it seems that ozone Fig. 7 Seasonal differences of standard emission factors (normalized to 1000 mmol m À2 s À1 of PAR and 30 1C leaf temperature) of monoterpene emission from A. tibourbou and isoprene emission from H. courbaril (panel b), in conjunction with data of ambient temperature and photosynthetic active radiation (PAR) in the days proceeding the measurements (panel a).…”

Whereas for extra-tropical regions model estimates of the emission of volatile organic compounds (VOC) predict strong responses to the strong annual cycles of foliar biomass, light intensity and temperature, the tropical regions stand out as a dominant source year round, with only little variability mainly due to the annual cycle of foliar biomass of drought-deciduous trees. As part of the Large Scale Biosphere Atmosphere Experiment in Amazônia (LBA-EUSTACH), a remote secondary tropical forest site was visited in the dry-to-wet season transition campaign, and the trace gas exchange of a strong isoprene emitter and a monoterpene emitter are compared to the wet-to-dry season transition investigations reported earlier. Strong seasonal differences of the emission capacity were observed. The standard emission factor for isoprene emission of young mature leaves of Hymenaea courbaril was about twofold in the end of the dry season (111.5 lgC g À1 h À1 or 41.2 nmol m À2 s À1 ) compared to old mature leaves investigated in the end of the wet season (45.4 lgC g À1 h À1 or 24.9 nmol m À2 s À1 ). Standardized monoterpene emission rate of Apeiba tibourbou were 2.1 and 3.6 lgC g À1 h À1 (or 0.3 and 0.8 nmol m À2 s -1 ), respectively. This change in species-specific VOC emission capacity was mirrored by a concurrent change in the ambient mixing ratios. The growth conditions vary less in tropical areas than in temperate regions of the world, and the seasonal differences in emission strength could not be reconciled solely with meteorological data of instantaneous light intensity and temperature. Hence the inadequacy of using a single standard emission factor to represent an entire seasonal cycle is apparent. Among a host of other potential factors, including the leaf developmental stage, water and nutrient status, and abiotic stresses like the oxidative capacity of the ambient air, predominantly the long-term growth temperature may be applied to predict the seasonal variability of the isoprene emission capacity. The dry season isoprene emission rates of H. courbaril measured at the canopy top were also compared to isoprene emissions of the shade-adapted species Sorocea guilleminiana growing in the understory. Despite the difference in VOC emission composition and canopy position, one common algorithm was able to predict the diel emission pattern of all three tree species.
