The pollution of the environment with toxic heavy metals is spreading throughout the world along with industrial progress. The present study deals with isolation, identification and characterization of heavy metal tolerant bacteria. Heavy metal tolerating bacteria was isolated from Mula river, Chinchwad, Pune, Maharashtra, India. On the basis of morphological, biochemical, 16S rDNA gene sequenc...
Metals have strong influence on development and growth of crops. To simulate how cereal crops are affected and/or tolerated from heavy metal contamination by disposal of unregulated wastes as soil amendments, the nutrient culture experiment was conducted with barley (Hordeum vulgare L.), rice (Oryza sativa L.) and wheat (Triticum aestivum L.) at control (0), 1, 5, and 10 μM of copper (Cu), zinc...
The Sinorhizobium meliloti (S. meliloti) strain CCNWSX0020 displayed tolerance to high levels exposures of multiple metals and growth promotion of legume plants grown in metal-contaminated soil. However, the mechanism of metal-resistant strain remains unknown. We used five P1B-ATPases deletions by designating as ∆copA1b, ∆fixI1, ∆copA3, ∆zntA and ∆nia, respectively to investigate the role of P1...
Two full-length cDNAs (OmZnT1 and OmFET) encoding membrane transporters were identified by yeast functional screening in the heavy metal tolerant ericoid mycorrhizal isolate Oidiodendron maius Zn. OmZnT1 belongs to the Zn-Type subfamily of the cation diffusion facilitators, whereas OmFET belongs to the family of iron permeases. Their properties were investigated in yeast by functional complemen...
Little is known about the variability of response to heavy metal stress within tree species, although it could be a key for a better understanding of tolerance mechanisms and for breeding. The aim of the present study was to characterize the natural variation of response to cadmium (Cd) in Populus nigra L. in order to understand the mechanisms of Cd tolerance. For that, two P. nigra genotypes, ...
