To address the question how the recognition helix of the LexA repressor is positioned within the major groove of operator DNA we have applied a site-specific photocrosslinking approach using a LexA mutant repressor (LexA-C52) that harbors a single cysteine side chain in position 52, close to the COOH terminus of helix 3. The LexA-C52 mutant repressor has been purified and modified site-specific...

To achieve an accurate and comprehensive characterization of the multiscale pore–fracture characteristics Permian coal in Jingbian Block, Ordos Basin, a combination scanning electron microscopy (SEM), X-ray computed tomography (CT), nuclear magnetic resonance (NMR) techniques was utilized. With these experiments, mineral composition, pore size distribution (PSD), porosity, connectivity pores sa...

'Dwarf stature' maize variety offers promises to withstand unfavorable growth environments of Kharif season. But, for developing such variety, dwarf stature inbred lines must be available. Here, twenty-four F3 populations of white maize were evaluated though assessment of their genetic variability, heritability, and character association for selection of dwarf stature promising lines based on y...
