The auxin indole-3-acetic acid (IAA), which is essential for plant growth and development, is suggested to be synthesized via several redundant pathways. In maize (Zea mays), the nitrilase ZmNIT2 is expressed in auxin-synthesizing tissues and efficiently hydrolyses indole-3-acetonitrile to IAA. Zmnit2 transposon insertion mutants were compromised in root growth in young seedlings and sensitivit...

Rhodanese is a multifunctional, sulfur transferase that catalyzes the detoxification of cyanide by sulphuration in a double displacement (ping pong) mechanistic reaction. In the present study, small-insert metagenomic library from soil sample collected from Ladakh (3,000-3,600 m.a.s.l) in northwestern Himalayas, India was constructed. Function-driven screening of ~8,500 colonies led to the isol...

Phytoremediation counts as a major method for future which essentially needs resistance to contaminating agents. We pretreated the plants (Salix babylonica, as a model plant in phytoremediation of polluted waters) by sodium cyanide (0, 3 and 5 mg CN- L-1) to induce resistance with regard to acclimation and then examined their resistance to higher concentrations of cyanide. Accordingly, some of ...

background: besides acute lethal cyanide poisoning, its chronic intoxication may also produce some pathologic effects on different tissues that precedes alterations in biochemical parameters. the present study was aimed to evaluate the effects of sublethal cyanide exposure on some tissue enzyme activities in liver and kidney of rats. methods: twelve male rats were divided into two groups as fol...

Samples of the waste rock obtained from Marofengin South Africa ground 60, 70 and 80% passing 75µm were leached with cyanide in bottle roll tests. The results obtained showed that the percentage gold dissolution depends more on the ore size consists than on the cyanide concentration with the highest average dissolution rates of 88.75, 94.34 and 95.90% found at 600, 500 and 500 ppm, for 60, ...

“Il Principe” (the Prince) is the nickname given to a spectacular Mid Upper Palaeolithic (Gravettian) burial discovered at Arene Candide, Italy in 1942. Arene Candide is a large cave located about 90 m above sea level on the slope of the Caprazoppa promontory, along the Ligurian coast near Finale Ligure (Savona, Italy). The cave is named after a dune of white siliceous sand of aeolian origin, b...

Glutathione-S-Transferase (GST) in human cells has great importance the detoxification mechanism of carcinogenic chemicals. Therefore, may be a useful tumor marker. This study examines whether GST activity Gastric cancer (GC) and Colon Cancer (CC) is helpful marker diagnosing monitoring disease course. was investigated patients with CC GC healthy individuals. Erythrocyte isolation performed 3 m...
