“…76 Salt-induced VOC emissions include terpenes such as isoprene, mono-and sesquiterpenes, lipoxygenase (LOX) products, and methanol from Arabidopsis plants, which are relevant in priming stress tolerance and triggering induction of high salt resistance in neighboring plants. 77 Relative growth rate, stomatal conductance, and photosynthetic rate were significantly higher in exposed plants, making them better prepared for upcoming salt stress. 78…”

One of the most important challenges for individual plants is coexistence with their neighbors. To compensate for their sessile lifestyle, plants developed complex and sophisticated chemical systems of communication among each other. Site-specific biotic and abiotic factors constantly alter the physiological activity of plants, which causes them to release various secondary metabolites in their environments. Volatile organic compounds (VOCs) are the most common cues that reflect a plant's current physiological status. In this sense, the identity of its immediate neighbors may have the greatest impact for a plant, as they share the same available resources. Plants constantly monitor and respond to these cues with great sensitivity and discrimination, resulting in specific changes in their growth pattern and adjusting their physiology, morphology, and phenotype accordingly. Those typical competition responses in receivers may increase their fitness as they can be elicited even before the competition takes place. Plant-plant interactions are dynamic and complex as they can include many different and important surrounding cues. A major challenge for all individual plants is detecting and actively responding only to "true" cues that point to real upcoming threat. Such selective responses to highly specific cues embedded in volatile bouquets are of great ecological importance in understanding plant-plant interactions. We have reviewed recent research on the role of VOCs in complex plant-plant interactions in plant-cross kingdom and highlighted their influence on organisms at higher trophic levels.

“…“Priming” in plants can be defined as the intensification of defense responses occurring against previously encountered hostile factors, usually mediated by a complex network of priming targets and mechanisms ( Pastor et al, 2013a ; Balmer et al, 2015 ). Well-known examples of priming are the systemic acquired resistance (SAR; Fu and Dong, 2013 ) as well as the emission of volatile organic compounds (VOCs) upon plant attack by herbivores or by exposure to abiotic stress, which can trigger systemic defense responses even in neighboring plants ( Aranega-Bou et al, 2014 ; Lee and Seo, 2014 ). Early responses induced by priming mechanisms include changes in redox homeostasis and production of specific reactive oxygen species (ROS) signals, interacting with various other signaling molecules, such as hormones and reactive nitrogen species (RNS; Molassiotis et al, 2010 ; Mukherjee et al, 2010 ; Mittler et al, 2011 ; Pastor et al, 2013a , b ).…”

Analysis of the transgenerational iron deficiency stress memory in Arabidopsis thaliana plants

et al. 2015

We investigated the existence of the transgenerational memory of iron (Fe) deficiency stress, in Arabidopsis thaliana. Plants were grown under Fe deficiency/sufficiency, and so were their offspring. The frequency of somatic homologous recombination (SHR) events, of DNA strand breaks as well as the expression of the transcription elongation factor TFIIS-like gene increase when plants are grown under Fe deficiency. However, SHR frequency, DNA strand break events, and TFIIS-like gene expression do not increase further when plants are grown for more than one generation under the same stress, and furthermore, they decrease back to control values within two succeeding generations grown under control conditions, regardless of the Fe deficiency stress history of the mother plants. Seedlings produced from plants grown under Fe deficiency evolve more oxygen than control seedlings, when grown under Fe sufficiency: however, this trait is not associated with any change in the protein profile of the photosynthetic apparatus and is not transmitted to more than one generation. Lastly, plants grown for multiple generations under Fe deficiency produce seeds with greater longevity: however, this trait is not inherited in offspring generations unexposed to stress. These findings suggest the existence of multiple-step control of mechanisms to prevent a genuine and stable transgenerational transmission of Fe deficiency stress memory, with the tightest control on DNA integrity.

“…By analyzing 59 plant species representing 32 families in 23 orders, we found a high degree of variation with regard to damage-induced GLV release, both quantitatively and qualitatively. We focused this analysis on the capacity to produce GLV rather than analyzing the responses to herbivory or pathogen infection, as well as abiotic stresses, as described previously [1][2][3][4][5][6][7][8][9][10]. This is mainly because those stresses may individually alter the production of GLV.…”

“…In recent years, green leaf volatiles (GLV) were extensively characterized for their important role in the plant defense response against biotic and abiotic stresses, including insect herbivory and pathogen infection, as well as cold, heat, and salt stress [1][2][3][4][5][6][7][8][9]. Damaged plants almost instantly release GLV in large quantities, making them ideal chemical messengers for neighboring plants to prompt their defense responses [1][2][3].…”

Green leaf volatiles (GLVs) are commonly released by plants upon damage, thereby providing volatile signals for other plants to prepare against the major causes of damage, herbivory, pathogen infection, and cold stress. However, while the biosynthesis of these compounds is generally well understood, little is known about the qualities and quantities that are released by different plant species, nor is it known if release patterns can be associated with different clades of plants. Here, we provide a first study describing the damage-induced release of major GLVs by more than 50 plant species. We found major differences in the quantity and quality of those compounds between different plant species ranging from undetectable levels to almost 100 µg per gram fresh weight. We also found major shifts in the composition that correlate directly to the quantity of emitted GLV. However, we did not find any major patterns that would associate specific GLV release with distinct clades of plants.
