Abstract The responses of Populus euphratica Oliv. plants to soil water deficit were assessed by analyzing gene expression, protein profiles, and several plant performance criteria understand the acclimation deficit. Young, vegetatively propagated originating from an arid, saline field site submitted a gradually increasing for 4 weeks in greenhouse allowed recover 10 d after full reirrigation. Time-dependent changes intensity perturbations induced shoot root growth, xylem anatomy, gas...
Abstract To investigate early salt acclimation mechanisms in a salt-tolerant poplar species (Populus euphratica), the kinetics of molecular, metabolic, and physiological changes during 24-h exposure were measured. Three distinct phases stress identified by analyses osmotic pressure shoot water potential: dehydration, accumulation, restoration associated with ionic stress. The duration intensity these differed between leaves roots. Transcriptome analysis using P. euphratica-specific...
SUMMARY To explore the proteomic regulation that underlies physiological, anatomical, and chemical characteristics of wood in acclimation to changing light nitrogen (N), saplings Populus × canescens were treated with control or high irradiance combination low, N for 4 months. High led elevated levels starch, sucrose, glucose, fructose, decreased concentrations ammonium, nitrate, most amino acids total N, wider xylem, more xylem cell layers, narrower vessel lumina, longer fiber cells, greater...
Poplars are proposed for the phytoremediation of heavy metal (HM) polluted soil. Characterization genes involved in HM uptake and accumulation poplars is crucial improving efficiency. Here, Natural Resistance-Associated Macrophage Protein 1 (NRAMP1) encoding a transporter cadmium (Cd) transport was functionally characterized Populus × canescens. Eight putative PcNRAMPs were identified poplar genome most them primarily expressed roots. The expression PcNRAMP1 induced Cd-exposed roots it...
Abstract To investigate the pivotal physiological processes modulating lead (Pb) tolerance capacities of poplars, saplings two contrasting poplar species, Populus × canescens with high Pb sensitivity and nigra relatively low sensitivity, were treated either 0 or 8 mM for 6 weeks. Lead was absorbed by roots accumulated massively in leaves, leading to overproduction reactive oxygen reduced photosynthesis biomass both species. Particularly, index P. significantly lower than that nigra....
Quercus brantii is an important tree species in Zagros forests. Summer drought imposes severe limitations Q. forests, making reforestation with this general very difficult. This further complicated by the limited ecophysiological information for species. To improve our understanding of factors affecting tolerance at early critical life stages, we explored influence seed size and provenance on growth survival seedlings under drought. As expected, reduced increased root-to-shoot ratio, larger...
Abstract To investigate physiological and transcriptomic regulation mechanisms underlying the distinct net fluxes of NH4+ NO3− in different root segments Populus species under low nitrogen (N) conditions, we used saplings × canescens supplied with either 500 (normal N) or 50 (low μM NH4NO3. The NO3−, concentrations NH4+, amino acids organic enzymatic activities nitrite reductase (NiR) glutamine synthetase (GS) segment II (SII, 35–70 mm to apex) were lower than those I (SI, 0–35 apex)....
In the Mediterranean climate, plants, e.g., Quercus brantii Lindl, have evolved and adapted to bear up low soil-water soil-phosphorus conditions. Lindl. is a dominant tree species thorough Zagros forests. Phosphate-solubilizing bacteria (PSB) play crucial role in plant growth enhancement by solubilizing insoluble soil-phosphate. present study, effects of two indigenous PSB strains, Microbacterium sp. (M.) Streptomyces (S.) were individually combined evaluated on physiological traits brantii....
Aim of study: To identify and compare the early frost resistance mechanisms in three oak species (Quercus brantii, Quercus libani infectoria). Area Zagros forests Iran. Material methods: The physiological biochemical variables such as chlorophyll fluorescence, relative water content (RWC), electrolyte leakage, osmotic metabolite content, proline, glucose, potassium seedlings with varying altitudinal latitudinal ranges were measured under various treatments, including cold treatments (4°C:...
A considerable amount of cadmium (Cd) can accumulate in the bark poplar stems, but Cd transport pathway and its underlying molecular mechanisms remain unknown. Here, a radial stems previously unrecognized PcWRKY1-Yellow Stripe-Like 3 (PcYSL3) module that regulates are identified Populus × canescens (Aiton) Sm. Cadmiun-nicotianamine (Cd-NA) xylem vessels stem-wood is unloaded to adjacent ray parenchyma cells further radially transported bark-phloem. PcYSL3 putatively as involved stems. highly...
ABSTRACT Poplar plantations are often established on nitrogen‐poor land, and poplar growth wood formation constrained by low nitrogen (LN) availability. However, the molecular mechanisms which specific genes regulate in acclimation to LN availability remain unclear. Here, we report a previously unrecognized module, basic region/leucine zipper 55 (PtobZIP55)–PtoMYB170, regulates of Populus tomentosa PtobZIP55 was highly expressed induced LN. Altered anatomical properties increased...
Sodium and potassium ions have crucial roles in drought tolerant mechanisms of plants. In a pot experiment, seedlings Pistacia atlantica subsp. mutica were cultivated silty clay soil (Kex=21 mg/l, Naex=143 mg/l) exposed to different levels water content (90, 65 45% FC). P. maintained leaf transpiration rate, relative cation (Na+ K+) organs under moderate deficit (above permanent wilting point). At higher shortage, the amount rate tissues reduced, but Na+ K+ remained unaffected even severe...
Se evaluó la variación fenotípica en cuatro poblaciones naturales de Parrotia persica (Hamamelidaceae), una especie endémica considerada como un fósil viviente del bosque hircaniano, a través análisis morfométrico y multivariado las hojas. Asimismo, se estudiaron plasticidad asimetría foliar fluctuante (AFF). Nuestros hallazgos mostraron claramente divergencia significativa entre sitios. El tamaño más pequeño lámina foliar, grande los valores pequeños AFF fueron registrados sitios xéricos...
Abstract In recent years, the decline of Brant’s oak, main and most important tree Zagros, is widespread. Considering importance oak trees, this study aims to identify causal agent decline. Eight bacterial strains were isolated from infected tissues these eight isolates have been identified by phenotypic characteristics. Three induced typical hypersensitive reactions on tobacco leaves, suggesting that they pathogenic. Also, characterized as circular, gram-negative, facultatively anaerobic,...
