The involvement of exogenous abscisic acid (ABA) concentrations in common bean responses to saline stress was studied in two cultivars iffering in NaCl tolerance. To examine this, salt-sensitive (cv. Coco) and salt-tolerant (cv. Africa) plants in symbiosis with Rhizobium tropici IAT899 strain were grown under controlled conditions and treated with ABA previously to the saline treatment. Plants ...
laser is one of the sources that induce a biological effect in higher plants. the positive effect of laser on some crops has been proved. this research was carried out to study the effect of laser radiation on the accumulation of proline in spring wheat (triticum aestivum cv. kavir) under different nacl treatment levels. semi-coherent red beam, infrared beam and one-second harmonics of neodymiu...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
Drought is one of the most important environmental stresses that adversely affect plant growth and crop production will In order to study a factorial randomized complete block design with three replications in greenhouse Ardabil University mohaghegh was conducted in 2013. Treatments were water stress at three levels: 35%, 55% and 75% field capacity and seed inoculated with mycorrhiza growth pro...
Water shortage seriously threatens crop growth and development especially in semi-arid areas. Association of plants with beneficial soil microorganisms is a strategy for plant adaptation to environmental stresses. In this study, the effect of seed inoculation of rapeseed genotypes with mycorrhiza-like fungus (Piriformospora indica) and growth-promoting bacterium (Arthrobacter siccitolerans) was...
Rxt1/NTT4 (SLC6A17) belongs to a gene family of "orphan transporters" whose substrates and consequently functions remain unidentified. Although Rxt1/NTT4 was previously thought to function as a sodium-dependent plasma membrane transporter, recent studies localized the protein to synaptic vesicles of glutamatergic and GABAergic neurons. Here, we provide evidence indicating that Rxt1/NTT4 functio...
To investigate the effects of Cd and Cd-Sodium nitroproside (SNP) on growth and physiological parameters of Melia azedarach, this experiment was done in a completely randomized design in three replicates and arranged as factorial. Results showed the amounts of Cd and proline in the root of the plant significantly increased as Cd concentration in soil increased. Length and weight of roots decrea...
1. More than one mode of transport can be observed for concentrative uptake of a-aminoisobutyric acid (AIB) by rat kidney cortex slices when the initial concentration of AIB in the medium is varied between 0.2 and 16 mM. 2. The relative contribution from both systems to the total observed uptake at various concentrations of AIB was calculated. The K, values for the two systems were 3.87 rnM and...
In order to assess the effect of drought stress and various levels of potassium on solutes accumulation and chlorophyll of canola and Indian mustard, a field experiment was conducted in a factorial design based on randomized complete block design with three replications including three irrigation regimes (I1=irrigation after 50% depletion of soil water(control),I2 =irrigation after 70% water de...
