Interactive of arsenate and phosphate on arsenic-induced oxidative stress in root of Isatis cappadocica Desv.
In present study, growth, arsenic accumulation, and antioxidant responses in root of Isatis cappadocica were investigated in response to application of arsenate and phosphate. Reduction in root dry weights was significant with 1200 µM arsenate and 5 µM phosphate treatments. Phosphate had a steady effect on root dry weight improvement, especially in high arsenate treatments ≥ 200 μM. As concentr...
متن کاملMetabolic adaptations to arsenic-induced oxidative stress in Isatis cappadocica
Arsenic is considered as one of the most important environmental contaminant elements. Some plant species can grow in arsenic contaminated soils and they are able to reduce arsenic toxicity. In this study, a hydroponic experiment was conducted on Isatis cappadocica, a newly-discovered As hyperaccumulator. Accordingly, we conducted this experiment to compare the interaction of effect of arsenic ...
متن کاملThe effect of arsenic and sodium nitroprusside on the physiological responses and antioxidant enzymes activity of Isatis cappadocica
Arsenic (As) stress, through the creation of oxidative stress, can cause phytotoxicity (e.g. The decrease of growth and chlorophyll content) in plants. Nitric oxide (NO), by promotion of the antioxidant system, plays an important role in reducing heavy metal-induced oxidative stress. In this study, the role of exogenously applied sodium nitroprusside (SNP; a NO donor) on physiological responses...

متن کاملArsenic speciation, and arsenic and phosphate distribution in arsenic hyperaccumulator Pteris vittata L. and non-hyperaccumulator Pteris ensiformis L.
This study examined the roles of arsenic translocation and reduction, and P distribution in arsenic detoxification of Pteris vittata L. (Chinese Brake fern), an arsenic hyperaccumulator and Pteris ensiformis L. (Slender Brake fern), a non-arsenic hyperaccumulator. After growing in 20% Hoagland solution containing 0, 133 or 267 microM of sodium arsenate for 1, 5 or 10 d, the plants were separate...
