“…We found that there was little to no effect of increased CO 2 concentrations on E. grandis seedling physiology. This is similar to some studies (Kanechi & Ochi, 1998;Choi et al, 2011;Danyagri & Dang, 2013), but in disagreement with others (Idso & Kimball, 1993;Kirdmanee et al, 1995;Ghannoum et al, 2010). Other than base genetic effects (i.e.…”

SummaryUsing the newly available genome for Eucalyptus grandis, we sought to determine the genome-wide traits that enable this host to form mutualistic interactions with ectomycorrhizal (ECM) Pisolithus sp. and to determine how future predicted concentrations of atmospheric carbon dioxide (CO 2 ) will affect this relationship.We analyzed the physiological and transcriptomic responses of E. grandis during colonization by different Pisolithus sp. isolates under conditions of ambient (400 ppm) and elevated (650 ppm) CO 2 to tease out the gene expression profiles associated with colonization status.We demonstrate that E. grandis varies in its susceptibility to colonization by different Pisolithus isolates in a manner that is not predictable by geographic origin or the internal transcribed spacer (ITS)-based phylogeny of the fungal partner. Elevated concentrations of CO 2 alter the receptivity of E. grandis to Pisolithus, a change that is correlated to a dramatic shift in the transcriptomic profile of the root.These data provide a starting point for understanding how future environmental change may alter the signaling between plants and their ECM partners and is a step towards determining the mechanism behind previously observed shifts in Eucalypt-associated fungal communities exposed to elevated concentrations of atmospheric CO 2 .

“…Inorganic phosphate (P i ) concentration in cytosol largely determines the exportation of triose phosphate to cytosol or storage in chloroplasts (Lambers et al ) and thus affects both J max and TPU. The up‐regulations of V cmax , J max and TPU observed in this study are consistent with the findings of Long et al (), Darbah et al () and Danyagri and Dang () but are in contrast to the down‐regulations that are commonly reported in the literature, e.g. Tissue and Lewis () and Watanabe et al ().…”

Climate change will cause northward shifts of climate envelopes for boreal plants, however, the different photoperiod and soil moisture regimes at higher latitudes will likely influence the success of species migrations (natural and assisted). The objective of this study was to assess the effects of photoperiod regime and its interactions with soil moisture and carbon dioxide concentration ([CO 2 ]) on the morpho-physiological processes in jack pine Pinus banksiana. One-year old seedlings were exposed to two [CO 2 ] (400 and 950 mmol mol -1 ), two soil moistures (60-70% and 30-40% of field water capacity) and three photoperiod regimes (photoperiods at seed origin, 5° and 10° north of the seed origin) in environment controlled greenhouses. The impacts of photoperiod, soil moisture and elevated [CO 2 ] on growth and physiological processes in the seedlings were examined. The results suggest that the response of jack pine to climate change will be complex under the interactive effects of northward migration associated longer photoperiod, soil moisture stress and elevated [CO 2 ]. The longer photoperiod associated with higher latitudes under elevated [CO 2 ] significantly advanced the budburst at both high and low soil moisture regimes, which may likely increase the risk of late spring frosts damage prior to and during budburst. The interactive effects of longer photoperiod and low soil moisture significantly increased the water use efficiency under elevated [CO 2 ]. However, the significant 2-and 3-way interactions suggest that drought and longer photoperiods with northward migration will limit the positive effects of elevated [CO 2 ] on growth and physiological processes in the species. These results might have important implications in assisted migration/seed transfer of the species following climate change.

“…3). These correlations confirm once again that the impact of these elements can be interrelated, and also indicates the importance of the relationship between the reserves of the major nutrients in the soil (Michalik 1985, Ritter 2007, Danyagri and Dang 2014. The sensitivity of SOD, CAT, and POD to changes in soil conditions are noted in literature (Tombesi et al 1969, Gurgul and Herman 1994, Bourioug et al 2014.…”

“…As another key nutrient element for photosynthesis, P is often the most limiting or second most limiting element to the aboveground primary productivity. It is suggested that uptake of N and P from organic matter by plant roots is enhanced by ectomycorrhizal fungi that were present in the forest stands (Ritter 2007, Danyagri andDang 2014). However, the availability of N and its ratio to P level in the soil influence the expression of figure in the wood in Karelian birch, as indicated by variations in the activity of enzymes -SS, ApInv and nitrate reductase (NR).…”

The influence of major nutrients’ reserves (available to plants) – nitrogen (N), phosphorus (P), potassium (K) – in the top 25-cm layer of soil on the Karelian birch (Betula pendula Roth var. carelica (Mercl.) Hämet-Ahti) with non-figured and figured wood via the antioxidant enzymes’ activity was investigated. The analysis of sites in area where Karelian birch trees with varying degree of figured wood intensity were growing was carried out. The cambial zone of the sample trees during active cambial growth period was studied for the activity of AOS enzyme complex (superoxide dismutase (SOD); catalase (CAT); peroxidase (POD); polyphenol oxidase (PPO)). Cellulose content and lignin content were studied. It was noticed that the availability of major nutrients in the investigated sites had influence on the degree of figured wood intensity in Karelian birch plants. Thus, non-figured and figured Karelian birch plants that grew on sites with various levels of major nutrients’ reserves differed in the AOS enzymes’ activity, which was a consequence of different xylogenesis scenarios in the studied birch forms. It was supposed, that the certain site conditions (N, P, K levels) formation could affect the degree of figured wood intensity, cellulose and lignin content. The N level and P/N ratio had the most effects under the adequate K level. So AOS enzymes’ complex activity could indicate differences in Karelian birch wood quality in sites that differ in soil fertility (N, P, K levels).
