“…A burst of methanol emission is often observed upon oxidative stress (Beauchamp et al, ; Jiang et al, ; Li et al, ). Interestingly, peaking of methanol release in stressed angiosperms occurs typically before the burst of LOX release (Beauchamp et al, ; Jiang et al., ; Li et al, ), but in filmy ferns, the emission peak of methanol emission occurred 5–10 min after the peak in LOX volatile emission (Figure c). This evidence further supports the idea that ROS was first generated in the symplast, in particular, in photosynthetic membranes, and led to elicitation of a symplastic LOX burst first, followed by diffusion of ROS into cell walls and generation of the methanol emission burst.…”

“…Methanol release from plants results from the activity of pectin methylesterases that demethylate methyl ester groups is polygalactouronan chains in pectins (Micheli, 2001;Pelloux et al, 2007). Methanol release is particularly pronounced in growing plant tissues (Harley, Greenberg, Niinemets, & Guenther, 2007), but it is also activated upon different stresses (Beauchamp et al, 2005;Jiang et al, 2017;Li et al, 2017). Demethylation of pectins plays a major role in altering cell-wall rigidity, but the way demethylation of galactouronans alters cell-wall rigidity is not well understood.…”

“…High‐resolution direct monitoring of leaf oxidative status and overall stress level through desiccation–rewatering cycles is not feasible. However, a plethora of volatiles is released from stressed plants (Loreto & Schnitzler, ; Matsui, Sugimoto, Kakumyan, Khorobrykh, & Mano, ; Niinemets et al, ), and the release of several of stress volatiles is typically quantitatively associated with the severity of stress (Beauchamp et al, ; Jiang, Ye, Li, & Niinemets, ; Loreto & Schnitzler, ; Niinemets, Kännaste, & Copolovici, ). Among these volatiles, the release of lipoxygenase (LOX) pathway volatiles, a mixture of various C6 aldehydes and alcohols and their derivatives, is a ubiquitous response to different abiotic and biotic stresses; LOX volatiles are typically elicited upon severe stress that leads to membrane‐level damage (Beckett et al, ; Copolovici et al, ; Copolovici, Kännaste, Pazouki, & Niinemets, ; Copolovici, Väärtnõu, Portillo Estrada, & Niinemets, ; Kanagendran, Pazouki, & Niinemets, ; Li, Harley, & Niinemets, ).…”

Exposure to recurrent desiccation cycles carries a risk of accumulation of reactive oxygen species that can impair leaf physiological activity upon rehydration, but changes in filmy fern stress status through desiccation and rewatering cycles have been poorly studied. We studied foliage photosynthetic rate and volatile marker compounds characterizing cell wall modifications (methanol) and stress development (lipoxygenase [LOX] pathway volatiles and methanol) through desiccation-rewatering cycles in lower-canopy species Hymenoglossum cruentum and Hymenophyllum caudiculatum, lower- to upper-canopy species Hymenophyllum plicatum and upper-canopy species Hymenophyllum dentatum sampled from a common environment and hypothesized that lower canopy species respond more strongly to desiccation and rewatering. In all species, rates of photosynthesis and LOX volatile emission decreased with progression of desiccation, but LOX emission decreased with a slower rate than photosynthesis. Rewatering first led to an emission burst of LOX volatiles followed by methanol, indicating that the oxidative burst was elicited in the symplast and further propagated to cell walls. Changes in LOX emissions were more pronounced in the upper-canopy species that had a greater photosynthetic activity and likely a greater rate of production of photooxidants. We conclude that rewatering induces the most severe stress in filmy ferns, especially in the upper canopy species.

“…From these studies, five use ozone as the inducing abiotic stress (Beauchamp et al, 2005;Behnke et al, 2009;Pazouki et al, 2016;Li et al, 2017;Acton et al, 2018), six others apply biotic stressors and one both (Kanagendran et al, 2018b). From the abiotic stress experiments, two have exposed experimental plants to real insects (Mengistu et al, 2014;Yli-Pirilä et al, 2016), while four studies use mechanical wounding (Brilli et al, 2011;Erb et al, 2015;Portillo-Estrada et al, 2015;Kanagendran et al, 2018b) and two studies applied methyl-jasmonate (Faiola et al, 2015;Jiang et al, 2017) to mimic herbivory. Data are extracted from the literature either directly using the Engauge digitizer 10.11 software or from presented graphs by determining the turning points of emission developments.…”

The emission of biogenic volatile organic compounds (BVOCs) is usually thought to depend on species-specific emission capacities that vary with seasonal and phenological conditions. Actual-so called constitutive-emissions are then calculated from prevailing temperature and radiation. However, various abiotic and biotic stressors such as ozone, extreme radiation and temperature conditions, as well as wounding e.g., from insect feeding, can lead to de-novo emissions of stress-induced BVOCs (sBVOCs) that may excel constitutive emissions by more than an order of magnitude. These emissions often have a considerable different compound composition and are short-lived but can prolong under continuous stress for quite some time. Thus, they may easily have a large impact on overall regional BVOC emissions. However, sBVOCs are generally not considered in models since up to date no consistent mechanism has been proposed. This manuscript suggests a new mechanism based on the finding that sBVOCs originate from a handful of biosynthetic pathways which synthesize compounds in the groups of monoterpenes, sesquiterpenes, and green leave volatiles, as well as methyl salicylate, ethanol/acetaldehyde, methanol/formaldehyde, and acetone. Isoprene is also considered but since it is often constitutively emitted, the specific role of stress induction is difficult to determine for this compound. A function is proposed that describes the production of all de-novo sBVOCs sufficiently well and scales with stress intensity. It is hypothesized that the response delay and the form of the function is specific for the production pathway and valid for ozone as well as wounding (herbivory) induced stress. Model parameters are then derived from pooled literature data based on a metaanalysis of suitable induction-response measurements of different plant species. The overall emission amount derives from the intensity and frequency of the stress impulse. We present a number of literature studies that are used to parameterize the new model as well as a selection of evaluations for single-and multiple-stress inductions. Furthermore, coupling and interaction with constitutive emission models as well as limitations and possible further developments are discussed.

Cannabinoids are predominantly produced in the glandular trichomes on cannabis female flowers. There is little known on how cannabinoid biosynthesis is regulated during female flower development. We aim to understand the rate-limiting step(s) in the cannabinoid biosynthetic pathway. We investigated the transcript levels of cannabinoid biosynthetic genes together with cannabinoid contents during 7 weeks of female flower development. We demonstrated that the enzymatic steps for producing cannabigerol (CBG), which involve genes GPPS, PT, TKS, and OAC, could rate limit cannabinoid biosynthesis. Our findings further suggest that upregulation of cannabinoid synthases, CBDAS and THCAS in a commercial hemp and medical marijuana variety, respectively, is not critical for cannabinoid biosynthesis. The cannabinoid biosynthetic genes are generally upregulated during flower maturation; increased expression occurs coincident with glandular trichome development and cannabinoid production in the maturing flower. The results also suggest that different cannabis varieties may experience discrete transcriptional regulation of cannabinoid biosynthetic genes. In addition, we showed that methyl jasmonate (MeJA) can potentially increase cannabinoid production. We propose that biweekly applications of 100 μM MeJA starting from flower initiation would be efficacious for promoting cannabinoid biosynthesis. Our findings provide important genetic information for cannabis breeding to generate new varieties with favorable traits.
