“…In particular, O 3 can induce a different biomass allocation between above and below organs (as confirmed by the significant reduction in the root/ shoot ratio under 2.0_AA conditions; Wittig et al, 2009), even though the duration of O 3 exposure was not long enough to cause significant effects on total biomass (e.g., unchanged values of total dry weight values; Engela et al, 2021). A reduction of root dry weight occurred under elevated O 3 , regardless of concentration: this was probably due to a limitation in carbohydrate availability as consequence of leaf injury (Hoshika et al, 2020), alteration of membrane integrity and dysfunction of photosynthetic systems (King et al, 2005;Li et al, 2015;Ghosh et al, 2020).…”

“…Consequently, more severe O 3 effects on the Atlantic forest located in this subtropical region (mainly São Paulo and Rio de Janeiro States) are expected (Domingos et al, 2003; Moura et al, 2014, 2018). Ozone effects on native tree species from the Atlantic Forest have recently been determined in the field or experimentally, pointing to distinct tolerance levels and highlighting the need to expand knowledge on this topic (Cassimiro et al, 2016; Engela et al, 2021; Fernandes et al, 2019; Moura et al, 2018). In the SH, the Amazon spans over 629 million hectares of rainforest, accounting for 54% of the total rainforests left on Earth (Peng et al, 2020).…”

Although it is an integral part of global change, most of the research addressing the effects of climate change on forests have overlooked the role of environmental pollution. Similarly, most studies investigating the effects of air pollutants on forests have generally neglected the impacts of climate change. We review the current knowledge on combined air pollution and climate change effects on global forest ecosystems and identify several key research priorities as a roadmap for the future. Specifically, we recommend (1) the establishment of much denser array of monitoring sites, particularly in the South Hemisphere; (2) further integration of ground and satellite monitoring; (3) generation of flux‐based standards and critical levels taking into account the sensitivity of dominant forest tree species; (4) long‐term monitoring of N, S, P cycles and base cations deposition together at global scale; (5) intensification of experimental studies, addressing the combined effects of different abiotic factors on forests by assuring a better representation of taxonomic and functional diversity across the ~73,000 tree species on Earth; (6) more experimental focus on phenomics and genomics; (7) improved knowledge on key processes regulating the dynamics of radionuclides in forest systems; and (8) development of models integrating air pollution and climate change data from long‐term monitoring programs.

“…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). Several studies have revealed that the net photosynthesis rates in trees, wheat ( Triticum aestivum ), castor ( Ricinus communis L.), and Arabidopsis ( Arabidopsis thaliana ) considerably decrease in response to high ambient O 3 concentrations, which has generally been attributed to decreased carboxylation efficiency, electron transfer between photosystems I and II, and effects on stomata (Cotrozzi, 2021; Engela et al, 2021; Feng et al, 2008; Paoletti, 2006; Rathore & Chaudhary, 2019). Stomatal conductance is a key metric of plant sensitivity to O 3 (Hasan et al, 2021).…”

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.
