“…The reduction in A 390 may relate to the smaller crown span and stem diameter that were caused by EOZ. Elevated O 3 can alter nutrient composition, affect allocation to different organs, and have impacts in ecological stoichiometry of trees (Li et al 2017a;Shang et al 2018Shang et al , 2019. However, in this study, the only significant effect of O 3 on leaf nutrients content was for Na content in ECM-treated plants grown in EOZ, which was approximately half of that in ECM-treated plants grown in Fig.…”

“…Other O 3 molecules enter the leaf through stomata during gas exchange processes (Paoletti and Grulke 2005). Elevated O 3 uptake by stomata can inhibit leaf area growth, decrease carbon uptake and Rubisco and chlorophyll content, alter growth, and suppress productivity of forest plants (Paoletti and Grulke 2005;Wittig et al 2009;Jolivet et al 2016;Li et al 2017a, b;Cailleret et al 2018). Because of the negative O 3 effects on forest plants and associated ecological processes (Karnosky et al 2005;Ainsworth et al 2012;Blande et al 2014;Agathokleous et al 2016b;Chappelka and Grulke 2016;Braun et al 2017), we must understand the biology of O 3 -induced stress and devise innovative methods to mitigate the deleterious effects of O 3 .…”

other than ozone. Inoculation of roots with ectomycorrhizae had negligible influence on the effects of either soil nutrient availability or ozone. However, this lack of effect may be upon impeded formation of complete mycorrhizal root tips due to factors other than the manipulated variables. B and Na appeared to have an important role in stress responses, so further studies to examine their link with physiological mechanisms as a function of time. This study provides an important perspective for designing forestry practices to enhance seedling health.

Summary⍰ Modulation of stomatal development may be an acclimation response to low water availability. However, stomatal development plasticity has been assessed in very few species.⍰ We quantified leaf anatomy traits, including stomatal index (SI), density (SD), size (SS), and pore index (SPI), in response to water-deficit stress in river birch (Betula nigra L.), eastern redbud (Cercis canadensis L.), and silver maple (Acer saccharinum L.).⍰ Birch and redbud, but not maple, had reduced SPI in response to water deficit. The mechanism by which SPI reduction occurred (via SD or SS) varied among species and with severity of water stress. Despite reduced SPI in birch and redbud, anatomical changes were relatively small and had a minor to no effect on the theoretical maximum stomatal conductance. Furthermore, gas-exchange rates were equivalent to well-watered plants following media re-irrigation.⍰ In some tree species, stomatal development is downregulated in response to water deficit conditions. Stomatal development plasticity is facilitated by smaller or fewer stomata, depending upon the species and the intensity of the stress. Water-deficit-induced plasticity in stomatal development is species-specific, likely due to species adaptation to ecological niches.

The Acer truncatum Bunge is a particular forest tree species found in the north of China. Due to the recent discovery that its seeds contain a considerable amount of nervonic acid, this species has received more and more attention. However, there have been no reports of the genome in this species. In this study, we report on the Acer truncatum genome sequence produced by genome survey sequencing. In total, we obtained 61.90 Gbp of high-quality data, representing approximately 116x coverage of the Acer truncatum genome. The genomic characteristics of Acer truncatum include a genome size of 529.88 Mbp, a heterozygosis rate of 1.06% and a repeat rate of 48.8%. A total of 392,961 high-quality genomic SSR markers were developed and a graphical map of the annotated circular chloroplast genome was generated. Thus far, this is the first report of de novo whole genome sequencing and assembly of Acer truncatum. We believe that this genome sequence dataset may provide a new resource for future genomic analysis and molecular breeding studies of Acer truncatum.
