“…Our study also showed that elevated CO 2 did not offset the negative effects of elevated O 3 on the plant growth. This finding is in contrast to other studies in which elevated CO 2 has been shown to ameliorate the negative effects of elevated O 3 47 , 48 . These contradictory results may be due to the interactions between CO 2 and O 3 depending on plant species 49 and plant developmental stages 17 .…”

Elevated CO2 and O3 can affect aphid performance via altering plant nutrients, however, little is known about the role of plant secondary metabolites in this process, especially for aphids feeding behaviors. We determined the effects of elevated CO2 and O3 on the growth and phenolics of alfalfa (Medicago sativa) and feeding behaviors of the pea aphids (Acyrthosiphon pisum) and cowpea aphids (Aphis craccivora). Elevated CO2 improved plant growth, but could not completely offset the negative effects of elevated O3. Elevated O3 increased foliar genistin content at the vegetative stage, increased ferulic acid at the reproductive stage, and elevated CO2 increased those at both stages. Simultaneously elevated CO2 and O3 increased foliar ferulic acid content at the reproductive stage and increased genistin content at both stages. For pea aphids, feeding efficiency was reduced under elevated CO2 at the reproductive stage and decreased under elevated O3 at the vegetative stage. For cowpea aphids, feeding efficiency was increased under elevated CO2 at the vegetative stage and decreased under elevated O3 at both stages. Simultaneously elevated CO2 and O3 decreased both aphids feeding efficiency. We concluded that CO2 and O3 independently or interactively had different effects on two aphids feeding behaviors through altering foliar ferulic acid and genistin contents.

“…The role of hormone pathways in regulating the growth and metabolic responses to elevated CO 2 is not well known, despite there being a few reports (e.g., Li et al, 2011 ; Ribeiro et al, 2012 ; Zavala et al, 2013 ). Elevated CO 2 can promote an accumulation in the salicylic acid (SA, Zavala et al, 2013 ) and brassinosteroids (BR; Jiang et al, 2012 ), while reducing Jasmonates (JA) and ethylene concentrations ( Zavala et al, 2013 ; Vaughan et al, 2014 ).…”

“…In one recent report, BRs were found to enhance the stimulation of plant growth and photosynthetic potential under elevated CO 2 ( Jiang et al, 2012 ). An increase in the indole-3-acetic acid (IAA), isopentenyl-adenosine (iPA), and dihydrozeatin riboside (DHZR) was found, while a decrease in the ABA and unchangeable zeatin riboside (ZR) occurred in Pinus tabulaeformis plants exposed to elevated CO 2 , which can encounter O 3 exposure effects to alleviate damage ( Li et al, 2011 ). The iPA, DHZR, and ZR are recognized as the most commonly active cytokinins (CTKs) in plants.…”

Response and adaptation of photosynthesis, respiration, and antioxidant systems to elevated CO2 with environmental stress in plants

2015

It is well known that plant photosynthesis and respiration are two fundamental and crucial physiological processes, while the critical role of the antioxidant system in response to abiotic factors is still a focus point for investigating physiological stress. Although one key metabolic process and its response to climatic change have already been reported and reviewed, an integrative review, including several biological processes at multiple scales, has not been well reported. The current review will present a synthesis focusing on the underlying mechanisms in the responses to elevated CO2 at multiple scales, including molecular, cellular, biochemical, physiological, and individual aspects, particularly, for these biological processes under elevated CO2 with other key abiotic stresses, such as heat, drought, and ozone pollution, as well as nitrogen limitation. The present comprehensive review may add timely and substantial information about the topic in recent studies, while it presents what has been well established in previous reviews. First, an outline of the critical biological processes, and an overview of their roles in environmental regulation, is presented. Second, the research advances with regard to the individual subtopics are reviewed, including the response and adaptation of the photosynthetic capacity, respiration, and antioxidant system to CO2 enrichment alone, and its combination with other climatic change factors. Finally, the potential applications for plant responses at various levels to climate change are discussed. The above issue is currently of crucial concern worldwide, and this review may help in a better understanding of how plants deal with elevated CO2 using other mainstream abiotic factors, including molecular, cellular, biochemical, physiological, and whole individual processes, and the better management of the ecological environment, climate change, and sustainable development.

“…Previous studies have shown that because of strong oxidative stress, pre-exposure to O 3 can prime tomato leaves for an enhanced defense against subsequent herbivorous insect infestation by upregulating the expression of salicylic acid (SA)-dependent defensive gene pathogenesis-related protein and increasing the emission of jasmonic acid (JA)-mediated monoterpene volatiles by tomato plants to decrease the population abundance and feeding fitness of B. tabaci (Cui et al, 2012;Cui et al, 2014). In addition to the SA and JA signaling pathways, O 3 pre-exposure activates the abscisic acid (ABA) signaling pathway, with a significant increase in ABA accumulation via the direct oxidation of the ABA precursor xanthoxin and the expression of ABA-related genes in some species, such as Arabidopsis, tomato, and Chinese pine (Li et al, 2011;McAdam et al, 2017). ABA is an important signal in regulating phloem-sucking insect infestation (Kerchev et al, 2013;Hillwig et al, 2016).…”

O3-Induced Priming Defense Associated With the Abscisic Acid Signaling Pathway Enhances Plant Resistance to Bemisia tabaci

Elevated ozone (O 3) modulates phytohormone signals, which subsequently alters the interaction between plants and herbivorous insects. It has been reported that elevated O 3 activates the plant abscisic acid (ABA) signaling pathway, but its cascading effect on the performance of herbivorous insects remains unclear. Here, we used the ABA-deficient tomato mutant notabilis (not) and its wild type, Ailsa Craig (AC), to determine the role of ABA signaling in mediating the effects of elevated O 3 on Bemisia tabaci in field open-top chambers (OTCs). Our results showed that the population abundance and the total phloem-feeding duration of B. tabaci were decreased by O 3 exposure in AC plants compared with not plants. Moreover, elevated O 3 and B. tabaci infestation activated the ABA signaling pathway and enhanced callose deposition in AC plants but had little effect on those in not plants. The exogenous application of a callose synthesis inhibitor (2-DDG) neutralized O 3-induced resistance to B. tabaci, and the application of ABA enhanced callose deposition and exacerbated the negative effects of elevated O 3 on B. tabaci. However, the application of 2-DDG counteracted the negative effects of O 3 exposure on B. tabaci in ABA-treated AC plants. Collectively, this study revealed that callose deposition, which relied on the ABA signaling pathway, was an effective O 3-induced priming defense of tomato plants against B. tabaci infestation.
