Molecular diagnosis of sickle cell anaemia based on SNPs in β-globin gene

Abstract

This experimental study explores the possible role of three Hg-resistant bacterial strains in the enhanced growth of the mustard plant (Brassica juncea) under Hg-stress conditions. Under different concentrations of Hg, a pot scale experiment with Brassica juncea L. was performed to investigate the potential of bacterial strains for phytoremediation under Hg stress conditions. The results showed that all three strains, as well as their consortium, were capable of stimulating plant growth, biomass, and anti-oxidative enzyme activities. In comparison to the individual strains, the consortiums of all three strains were more prominent in the intensification of Brassica juncea L. physiological activity. Under Hg-stress conditions, all three strains increased the level of antioxidative content in Brassica juncea, indicating an increase in enzyme activity to cope with oxidative stress. Among all the three strains, Citrobacter Freundii (IITISM25) showed the highest accumulation potential in B. juncea followed by Morganella morganii (IITISM23) and Brevundimonas Dimunta (IITISM22). Hence, the results suggest that the IITISM22, IITISM23, IITISM25 strains and their consortium are very effective in phytoremediation and promote Brassica juncea growth under Hg-stress conditions.
