Expression of a mouse selenocysteine lyase in Brassica juncea chloroplasts affects selenium tolerance and accumulation
Selenium is an essential nutrient for many organisms, as part of certain selenoproteins. However, selenium is toxic at high levels, which is thought to be due to non-specific replacement of cysteine by selenocysteine leading to disruption of protein function. In an attempt to prevent non-specific incorporation of selenocysteine into proteins and to possibly enhance plant selenium tolerance and ...
متن کاملEffects of selenium accumulation on reproductive functions in Brassica juncea and Stanleya pinnata
Selenium (Se) is an essential micronutrient for many organisms, but is also a toxin and environmental pollutant at elevated levels. Due to its chemical similarity to sulphur, most plants readily take up and assimilate Se. Se accumulators such as Brassica juncea can accumulate Se between 0.01% and 0.1% of dry weight (DW), and Se hyperaccumulators such as Stanleya pinnata (Brassicaeae) contain be...
متن کاملSelenium accumulation protects Brassica juncea from invertebrate herbivory and fungal infection
• Certain plant species hyperaccumulate selenium (Se) up to 0.6% of their dry weight. It is not known whether Se hyperaccumulation offers the plants any advantage. In this study the hypothesis was tested that Se can protect plants from invertebrate herbivory or fungal infection. • Indian mustard ( Brassica juncea ) plants grown with or without Se were subjected to herbivory by caterpillars ( Pi...
متن کاملHeavy metal toxicity: Effect on plant growth, biochemical parameters and metal accumulation by Brassica juncea L.
Plant growth, pigment concentration, biochemical parameters and uptake of heavy metals were determined for Brassica juncea L. in response to cadmium and lead stress. The plant exhibited a decline in growth, chlorophyll content and carotenoids with Cd and Pb but Cd was found to be more detrimental than Pb treatment in B. juncea. The protein content was decreased by Cd (900 μM) to 95% and 44% by ...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
