“…This result is different from heat-stressed B. nigra , where emissions of glucosinolate breakdown products and LOX compounds occurred similarly [ 47 ]. Over the longer term, O 3 treatment and water-deficit can lead to modifications in glucosinolate content [ 34 , 54 , 96 ], and this could further contribute to alterations in the release of glucosinolate breakdown products under O 3 or other stresses.…”

Combined Acute Ozone and Water Stress Alters the Quantitative Relationships between O3 Uptake, Photosynthetic Characteristics and Volatile Emissions in Brassica nigra

Ozone (O3) entry into plant leaves depends on atmospheric O3 concentration, exposure time and openness of stomata. O3 negatively impacts photosynthesis rate (A) and might induce the release of reactive volatile organic compounds (VOCs) that can quench O3, and thereby partly ameliorate O3 stress. Water stress reduces stomatal conductance (gs) and O3 uptake and can affect VOC release and O3 quenching by VOC, but the interactive effects of O3 exposure and water stress, as possibly mediated by VOC, are poorly understood. Well-watered (WW) and water-stressed (WS) Brassica nigra plants were exposed to 250 and 550 ppb O3 for 1 h, and O3 uptake rates, photosynthetic characteristics and VOC emissions were measured through 22 h recovery. The highest O3 uptake was observed in WW plants exposed to 550 ppb O3 with the greatest reduction and poorest recovery of gs and A, and elicitation of lipoxygenase (LOX) pathway volatiles 10 min–1.5 h after exposure indicating cellular damage. Ozone uptake was similar in 250 ppb WW and 550 ppb WS plants and, in both treatments, O3-dependent reduction in photosynthetic characteristics was moderate and fully reversible, and VOC emissions were little affected. Water stress alone did not affect the total amount and composition of VOC emissions. The results indicate that drought ameliorated O3 stress by reducing O3 uptake through stomatal closure and the two stresses operated in an antagonistic manner in B. nigra.

“…In O 3 -stressed B. campestris L. ssp. chinensis [ 54 ] and B. napus [ 55 ], the content of different glucosinolates was differently affected. In another study, O 3 levels of 70, 80 and 120 ppb had no significant effect on VOCs emitted by leaves and flowers of B. nigra [ 56 , 57 ].…”

“…Accumulation of aromatic and indole GSL under O 3 stress can enhance the mechanism of antioxidant damage and physical damage resistance in plants, and then induce the accumulation of JA and SA, which promote the biosynthesis of indole GSL and aromatic GSL ( Han et al, 2021 ). Therefore, O 3 regulates the biosynthesis of GSL by inducing the production of ROS and activating the JA and SA signal transduction pathways ( Zhang et al, 2017 ).…”

Cruciferous vegetable crops are grown widely around the world, which supply a multitude of health-related micronutrients, phytochemicals, and antioxidant compounds. Glucosinolates (GSLs) are specialized metabolites found widely in cruciferous vegetables, which are not only related to flavor formation but also have anti-cancer, disease-resistance, and insect-resistance properties. The content and components of GSLs in the Cruciferae are not only related to genotypes and environmental factors but also are influenced by hormones, plant growth regulators, and mineral elements. This review discusses the effects of different exogenous substances on the GSL content and composition, and analyzes the molecular mechanism by which these substances regulate the biosynthesis of GSLs. Based on the current research status, future research directions are also proposed.

“…O 3 can affect the physiological and biochemical characteristics of plants, causing visible foliar injury, decreased photosynthesis, stomatal closure, chlorophyll degradation, high levels of reactive oxygen species (ROS) production, metabolic disorder, accelerated senescence, and suppressed productivity (Ainsworth, 2017; Feng et al, 2008; Han et al, 2021; Rathore & Chaudhary, 2019). Visible leaf injury induced by chronic O 3 exposure varies depending on the species and exposure conditions (Feng et al, 2014; Li et al, 2015; Shang et al, 2020).…”

The increasing ground-level ozone (O 3 ) pollution resulting from rapid global urbanization and industrialization has negative effects on many plants. Nonetheless, many gaps remain in our knowledge of how ornamental plants respond to O 3 . Rose (Rosa hybrida L.) is a commercially important ornamental plant worldwide. In this study, we exposed four rose cultivars ("Schloss Mannheim," "Iceberg," "Lüye," and "Spectra") to either unfiltered ambient air (NF), unfiltered ambient air plus 40 ppb O 3 (NF40), or unfiltered ambient air plus 80 ppb O 3 (NF80). Only the cultivar "Schloss Mannheim" showed significant O 3 -related effects, including foliar injury, reduced chlorophyll content, reduced net photosynthetic rate, reduced stomatal conductance, and reduced stomatal apertures. In "Schloss Mannheim," several transcription factor genes-HSF, WRKY, and MYB genes-were upregulated by O 3 exposure, and their expression was correlated with that of NCED1, PP2Cs, PYR/PYL, and UGTs, which are related to ABA biosynthesis and signaling. These results suggest that HSF, WRKY, and MYB transcription factors and ABA are important components of the plant response to O 3 stress, suggesting a possible strategy for cultivating O 3 -tolerant rose varieties.
