Phytochelatins are involved in differential arsenate tolerance in Holcus lanatus.
Arsenate tolerance is conferred by suppression of the high-affinity phosphate/arsenate uptake system, which greatly reduces arsenate influx in a number of higher plant species. Despite this suppressed uptake, arsenate-tolerant plants can still accumulate high levels of As over their lifetime, suggesting that constitutive detoxification mechanisms may be required. Phytochelatins are thiol-rich p...
متن کاملInteractive 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 کاملArsenate-induced Renal Agenesis in Rats192
The developmental origin of arsenate-induced renal agenesis was investigated. Pregnant Wistar rats were each injected once ip with 45 mgkg sodium arsenate a t day 10 (sperm day = day 0). Pregnancy was terminated a t various times following injection and the embryos recovered and serially sectioned. Renal agenesis resulted when the mesonephric duct failed to give rise to a ureteric bud with subs...

متن کاملSynthesis and thermodynamic properties of arsenate and sulfate-arsenate ettringite structure phases
Arsenic is a toxic and carcinogenic contaminant of potential concern. Ettringite [Ca6Al2(SO4)3(OH)12·26H2O] has the ability to incorporate oxyanions as a solid solution with SO42-, which could lower the soluble oxyanion concentrations. Therefore, ettringite containing SO42- and AsO43- has been synthesized. Results indicated that AsO43- could substitute for SO42- inside the channels of ettringit...
