We compared the effects of salt-stresses (SS, 1: 1 molar ratio NaCl to Na2SO4) and alkali-stresses (AS, NaHCO3 Na2CO3) on growth, photosynthesis, solute accumulation, ion balance barley seedlings, elucidate mechanism AS (high-pH) damage plants physiological adaptive AS. The SS water content, root system activity, membrane permeability, content photosynthetic pigments were much less than those However, damaged function, pigments, system, led severe reductions in net rate, a sharp increase...
The seedlings of wheat were treated by salt-stress (SS, molar ratio NaCl: Na2SO4 = 1: 1) and alkali-stress (AS, NaHCO3: Na2CO3 1). Relative growth rate (RGR), leaf area, water content decreased with increasing salinity, the extents reduction under AS greater than those SS. contents photosynthetic pigments did not decrease SS, but increased at low salinity. On contrary, sharply Under changes net (P N), stomatal conductance (g s), transpiration (E) similar all varied in a single-peak curve...
It is well known that salt stress has different effects on old and young tissues. However, it remains largely unexplored whether tissues have regulatory mechanism during adaptation of plants to stress. The aim this study was investigate the ion balance nitrogen metabolism in leaves rice, compare functions both organs rice tolerance.Rice protected from harm via large accumulation Na+ Cl- leaves. up-regulation OsHKT1;1, OsHAK10 OsHAK16 might contribute under In addition, lower expression...
Significance Hexaploid bread wheat is generally more salt tolerant than its tetraploid progenitor. However, the physiological bases and relative contributions of immediate effects polyploidization subsequently acquired adaptive changes in tolerance hexaploid remained elusive. This study compared a large suite morphophysiological traits synthetic natural wheats, their diploid progenitors, under normal salt-stressed conditions, studied subgenome-specific expression critical salt-tolerance...
Seedlings of Chloris virgata were treated with varying (0-160 mM) salt-stress (SS; 1: 1 molar ratio NaCl to Na2SO4) or alkali-stress (AS; NaHCO3 Na2CO3). To compare these effects, relative growth rates (RGR), stored energy, photosynthetic pigment contents, net rates, stomatal conductance, and transpiration determined. Both stresses did not change significantly the parameters C. under moderate stress (below 120 mM). Photosynthetic ability decreased only at high (160 Thus virgata, a natural...
Rice seedlings were stressed with salt stress or alkali stress. The growth, organic acids (OAs) and inorganic ions in measured to investigate the physiological adaptive mechanism by which rice tolerates results showed that injury effect of on was stronger than Under stress, anions dominant maintaining intracellular ionic equilibrium; however, under contents decreased, caused a severe deficit negative charge. charge remedied greatly accumulated OAs, especially malate citrate, OAs components...
Subgenome integrity in bread wheat (Triticum aestivum; BBAADD) makes possible the extraction of its BBAA component to restitute a novel plant type. The availability such ploidy-reversed (extracted tetraploid [ETW]) provides unique opportunity address whether and what extent has been modified phenotype, karyotype, gene expression during evolutionary history at allohexaploid level. We report here that ETW was anomalous multiple phenotypic traits but maintained stable karyotype....
In this study, cotton seedlings were subjected to osmotic-, salt- and alkali stresses. The growth, photosynthesis, inorganic ions, organic acids in the stressed measured, compare mechanisms by which plants adapt these stresses attempt probe high pH stress. Our results indicated that, at stress intensity, both osmotic showed a stronger injurious effect on growth photosynthesis than salt Cotton accumulated large amount of Na+ under stresses, but not addition, reductions K+, NO3 -, H2PO4 - much...
Background Alkali stress is an important agricultural contaminant and has complex effects on plant metabolism. The aim of this study was to investigate whether the alkali different growth, ion balance, nitrogen metabolism in old young leaves rice plants, compare functions both organs tolerance. Methodology/Principal Findings results showed that only produced a small effect growth leaves, whereas strongly damaged leaves. Rice protected from harm via large accumulation Na+ Cl− up-regulation...
Soil salinization is an important agriculture-related environmental problem. Alkali stress and salt strongly influence the metabolic balance in plants. Salt alkali stresses exert varied effects on old young tissues, which display different adaptive strategies. In this study, we used cotton (Gossypium hirsutum L.) plants as experimental material to investigate whether induces ionic metabolism changes leaves of exposed stress. Results showed that exerted a considerably stronger growth...
Abstract Enhancing the frequency and intensity of extreme high temperature conditions due to global warming largely deteriorates salt‐induced harm crop plants living in saline lands, which leads losses agricultural production. In northern China, spring wheat is grown many slightly areas often subjected a combination salt heat stresses. this study, cultivar was selected as experimental material stress (S), (H) their (S + H). Physiological analysis showed that inhibitory effect S H on growth...
Seedlings of Chloris virgata , an alkali‐tolerant halophyte, were stressed with a range salt stress (molar ratio NaCl:Na 2 SO 4 = 1:1, 40–200 mM, pH 6.48–6.65) or alkali NaHCO 3 :Na CO 9.93–9.97). Contents organic acids (OAs) and inorganic ions measured, the OAs in secretions analyzed, to probe physiological roles alkali‐tolerance. Under stress, Na + sharply increased, NO − H PO decreased shoots, which caused severe deficit negative charge. This was greatly remedied by OA. We propose that OA...
Two species with different resistances to alkaline pH, the glycophylic Triticum aestivum (wheat) and halophilic Chloris virgata, were chosen as test organisms. The salt-alkaline (SA) mixed stress conditions buffer capacities (BC) but same salt molarities pH established by mixing neutral (NaCl, Na2SO4), salts (NaHCO3 Na2CO3) in various proportions. Growth, photosynthetic characteristics, solute accumulation of seedlings monitored validity BC a decisive index alkali-stress (AS) intensity SA...
In this study, tomato ( Lycopersicon esculentum Mill.) plant seedlings were subjected to Na‐ or K‐salt stress and K‐alkali stress. The growth, photosynthesis, concentrations of solutes inorganic ions in dry samples stressed measured identify the physiological adaptive mechanisms by which plants tolerate alkali stresses. results showed that stresses (Na‐ stresses) significantly inhibited growth inhibitory effects on photosynthesis greater for Na‐salt accumulation balance closely related types...
Core Ideas Different tissues displayed different N‐metabolic responses to drought condition. Drought stress enhanced N uptake and assimilation in maize roots. AMT1;1b, AMT1;3, NRT1;2 NRT2;5 play important roles tolerance. Nitrogen metabolism has plant tolerance, higher can enhance The aim of this study was investigate the role regulation We measured expression genes known be involved assimilation, together with various photosynthetic parameters, nutrient content, from plants exposed water...
