Salt stress in soils impacts grain crop yield. Soil amendment with biochar and arbuscular mycorrhizal alone has been analyzed to improve the growth of several crops under salinity stress. However, combined application fungi for remediation improvement productivity wheat are rarely discussed have remained unclear. Therefore, this experiment was performed investigate effect (150 g per each treate...

background and objective: pigment production by microorganisms is important due to more rapid growth, higher efficiency, easier extraction, and antimicrobial effects compared to other methods. the aim of the present study is to isolate and identify antibiotic pigment-producing actinomycetes from the soil of the persian gulf and to evaluate the antibiotic activity of their pigments in the second...

to assess nickel-induced toxicity in plants, zea mays seeds were germinated and cultured on nutrient solution with nickel concentrations of 0, 50, 100 and 200 μm for a period of two weeks. its effects on the growth, hill reaction and photosynthetic pigments content were then investigated. the fresh and dry weight of leaves and roots increased in 50 μm nickel, but decreased in 100 and 200 μm. th...

The evaluation of induced chromosome doubling as a method of plant breeding requires more information on the specific effects of chromosome doubling than is available at the present time. It is important that this information be procured from comparisons of related diploid and tetraploid strains of known origin and similar genetic constitution, Such strains have not been generally available bec...

To better understand the evolution of red-green color vision in vertebrates, we inferred the amino acid sequences of the ancestral pigments of 11 selected visual pigments: the LWS pigments of cave fish (Astyanax fasciatus), frog (Xenopus laevis), chicken (Gallus gallus), chameleon (Anolis carolinensis), goat (Capra hircus), and human (Homo sapiens);and the MWS pigments of cave fish, gecko (Gekk...

BACKGROUND Traditional submerged fermentation mainly accumulates intracellular orange pigments with absorption maxima at 470 nm, whereas extractive fermentation of Monascus spp. with Triton X-100 can promote the export of intracellular pigments to extracellular broth, mainly obtaining extracellular yellow pigments with absorption maxima at approximately 410 nm. In this study, a strain of Monasc...

PURPOSE Salamander retinas are known to contain at least three cone pigments and two rod pigments. The purpose of this study was to clone and characterize the visual pigments from salamander cones. METHODS cDNA fragments of cone pigments were amplified from a salamander retina cDNA library by PCR using a pair of primers with consensus for visual pigments. These fragments were cloned and used ...

Abstract The effect of short-term and long-term root treatment with melatonin on growth parameters, photochemical activity PSII, content basic photosynthetic pigments, lipid peroxidation, accumulation inorganic ions in barley plants under the action cadmium chloride was studied. It shown for first time that protective phytomelatonin during is manifested a decrease toxic pigments shoots roots pl...

Accelerated cut-edge corrosion performance of commercialized full waterborne coating systems containing enviro-friendly inhibitors was studied on 55 wt% Al, 44 Zn and 1 Si galvanized steel in 5 NaCl solution at ambient temperature via the Scanning Vibrating Electrode Technique (SVET). At same volume content (7–11 wt%), benzotriazole pigments had a better overall than calcium ion exchanged silic...
