Alleviation of heavy metals toxicity by the application of plant growth promoting rhizobacteria and effects on wheat grown in saline sodic field.

The aim of the study was to determine tolerance of plant growth promoting rhizobacteria (PGPR) in different concentrations of Cu, Cr, Co, Cd, Ni, Mn, and Pb and to evaluate the PGPR-modulated bioavailability of different heavy metals in the rhizosphere soil and wheat tissues, grown in saline sodic soil. Bacillus cereus and Pseudomonas moraviensis were isolated from Cenchrus ciliaris L. growing in the Khewra salt range.

Synthesis, chemical characterization, DNA binding, antioxidant, antibacterial, and antifungal activities of ferrocence incorporated selenoureas.

Ferrocene-incorporated selenoureas 1-(4-methoxybenzoyl)-3-(4-ferrocenylphenyl)selenourea (P4Me), 1-(3-methoxybenzoyl)-3-(4-ferrocenylphenyl)selenourea (P3Me), and 1-(2-methoxybenzoyl)-3-(4-ferrocenylphenyl)selenourea (P2Me) were synthesized and characterized by nuclear magnetic resonance, Fourier transform infrared spectroscopy, atomic absorption spectroscopy, CHNS, and single-crystal X-ray diffraction. DNA interaction of the compounds was investigated with cyclic voltammetry, UV-visible spectroscopy, and viscometry, which is a prerequisite for anticancer agents. Drug-DNA binding constant was found to vary in the sequence: K(P4Me) (4.
