To characterize the dynamics of Cd²⁺ flux in rhizosphere and to study cadmium (Cd) plant-internal partitioning roots, wood, bark leaves relation energy metabolism, reactive oxygen species (ROS) formation antioxidants, Populus × canescens plantlets were exposed either 0 or 50 µM CdSO₄ for up 20 days nutrient solution. A strong net influx root apex was observed after Cd exposure 24 h, even if decreased gradually roots. large amount accumulated ions uploaded via xylem further transported phloem...
To investigate N metabolism of two contrasting Populus species in acclimation to low availability, saplings slow-growing (Populus popularis, Pp) and a fast-growing alba × glandulosa, Pg) were exposed 10, 100, or 1000 μM NH4NO3. Despite greater root biomass fine surface area Pp, lower net influxes NH4+ NO3– at the detected Pp compared those Pg, corresponding well content total concentration roots. Meanwhile, higher stable isotope composition (δ15N) roots stronger responsiveness...
Summary Overexpression of bacterial γ‐glutamylcysteine synthetase in the cytosol P opulus tremula × . alba produces higher glutathione ( GSH ) concentrations leaves, thereby indicating potential for cadmium C d) phytoremediation. However, net d 2+ influx association with H + / a , tolerance, and underlying molecular physiological mechanisms are uncharacterized these poplars. We assessed influx, tolerance transcriptional regulation several genes involved transport detoxification wild‐type...
Bark tissue of Populus × canescens can hyperaccumulate cadmium, but microstructural, transcriptomic, and physiological response mechanisms are poorly understood. Histochemical assays, transmission electron microscopic observations, energy-dispersive x-ray microanalysis, transcriptomic analyses have been performed to enhance our understanding cadmium accumulation detoxification in P. canescens. Cadmium was allocated the phloem bark, subcellular compartmentalization occurred mainly vacuoles...
Abstract Artificial photosynthesis can be used to store solar energy and reduce CO 2 into fuels potentially alleviate global warming the crisis. Compared generation of gaseous products, it remains a great challenge tune product distribution artificial liquid fuels, such as CH 3 OH, which are suitable for storage transport. Herein, we describe introduction metallic Cu nanoparticles (NPs) on O films change from products bare predominantly OH by reduction in aqueous solutions. The specifically...
Abstract Ectomycorrhizas (EMs) alleviate stress tolerance of host plants, but the underlying molecular mechanisms are unknown. To elucidate basis EM-induced physiological changes and their involvement in adaptation, we investigated metabolic transcriptional profiles EM non-EM roots gray poplar (Populus × canescens) presence absence osmotic imposed by excess salinity. Colonization with ectomycorrhizal fungus Paxillus involutus increased root cell volumes, a response associated carbohydrate...
Nitrogen (N) starvation and excess have distinct effects on N uptake metabolism in poplars, but the global transcriptomic changes underlying morphological physiological acclimation to altered availability are unknown. We found that stimulated fine root length surface area by 54 49%, respectively, decreased net photosynthetic rate 15% reduced concentrations of NH4+,NO3− total free amino acids roots leaves Populus simonii Carr. comparison with normal supply, whereas had opposite effect most...
To investigate how N-fertilization affects the growth, carbon and nitrogen (N) physiology, wood properties of poplars with contrasting growth characteristics, slow-growing (Populus popularis, Pp) fast-growing (P. alba×P. glandulosa, Pg) poplar saplings were exposed to different N levels. Above-ground biomass, leaf area, photosynthetic rates (A), instantaneous use efficiency (PNUEi), chlorophyll foliar sugar concentrations higher in Pg than Pp. Foliar nitrate reductase (NR) activities root...
Ectomycorrhizas ( EMs ), which are symbiotic organs formed between tree roots and certain fungi, can mediate cadmium Cd ) tolerance of host plants, but the underlying physiological molecular mechanisms not fully understood. P opulus × canescens was inoculated with or without axillus involutus (strain MAJ subsequently exposed to 0 50 μM CdSO 4 . Higher net 2+ influx in well corresponded higher transcript levels genes involved uptake, transport detoxification processes than those...
A greenhouse experiment was conducted to study whether exogenous abscisic acid (ABA) mediates the responses of poplars excess zinc (Zn). Populus × canescens seedlings were treated with either basal or Zn levels and 0 10 μm ABA. Excess led reduced photosynthetic rates, increased accumulation, induced foliar ABA salicylic (SA), decreased gibberellin (GA3 ) auxin (IAA), elevated root H2 O2 levels, ratios glutathione (GSH) GSSG ascorbate (ASC) dehydroascorbate (DHA) in poplars. While...
Phosphorus (P) and nitrogen (N) are the two essential macronutrients for tree growth development. To elucidate P N physiology of woody plants during acclimation to and/or starvation, we exposed saplings slow-growing Populus simonii Carr (Ps) fast-growing × euramericana Dode (Pe) complete nutrients or starvation P, both elements (NP). P. had lower concentrations greater amounts due higher biomass production, thereby resulting in phosphorus use efficiency/N efficiency (PUE/NUE) compared with...
Drought-induced tree mortality, which rapidly alters forest ecosystem composition, structure, and function, as well the feedbacks between biosphere climate, has occurred worldwide over past few decades, is expected to increase pervasively climate change progresses. The objectives of this review are (1) highlight likely ecological consequences drought-induced (2) synthesize hypotheses related (3) discuss implications current knowledge for modeling mortality processes under change, (4) future...
High temperature (HT) and drought are both critical factors that constrain tree growth survival under global climate change, but it is surprising the transcriptomic reprogramming physiological relays involved in response to HT and/or remain unknown woody plants. Thus, Populus simonii saplings were exposed either ambient or combined with sufficient watering drought. RNA-sequencing analysis showed a large number of genes differentially expressed poplar roots leaves desiccation, only small...
Glutathione (GSH) plays an important role in cadmium (Cd) tolerance woody plants, but the underlying mechanisms remain largely unknown. To elucidate physiological and transcriptional regulation of GSH-mediated Cd we exposed Populus × canescens (Ait.) Smith saplings to either 0 or 75 μM together with one three external GSH levels. treatments include buthionine sulfoximine (BSO, inhibitor biosynthesis), no exogenous GSH. External resulted higher Cd2+ uptake rate roots, greater amount poplars,...
Abstract The quickly rising atmospheric carbon dioxide (CO 2 )‐levels, justify the need to explore all (C) sequestration possibilities that might mitigate current CO increase. Here, we report likely impact of future increases in on woody biomass production three poplar species ( Populus alba L. clone 2AS‐11, nigra Jean Pourtet and × euramericana I‐214). Trees were growing a high‐density coppice plantation during second rotation (i.e., regrowth after coppice; 2002–2004; POPFACE/EUROFACE). Six...
Populus × euramericana (Pe) displays higher stable carbon isotope composition (δ(13)C) and intrinsic water use efficiency (WUEi) than cathayana (Pc) under unlimited conditions, rendering us to hypothesize that Pe is better acclimated deficiency Pc. To examine this hypothesis, saplings of Pc were exposed drought subsequently re-watered. exhibited distinct anatomical, physiological transcriptional responses in acclimation re-watering, mainly due stronger responsiveness regulation genes...
